1993 Rock FoxTV converted to 56k in 1996 to -allow-4 modem broadcast Vid 1 1993 Rock FoxTV
Founded by Eugène Meylan in 1914, Glycine produced watches at a factory in Bienne, Switzerland. Glycine began producing specialty ladies watches with precise, small movements in cases of gold and platinum dressed with diamonds and precious stones. In 1931 Glycine created an automatic movement based on the Hardwood 180 degree “Bumper” which had a repair feature providing the watch maker the ability to remove the automatic portion of the watch without disabling the movement.In 1952 Glycine introduced the VACUUM chronometers, which were touted for their resistance to water and shock. In 1953, Glycine introduced the most famous of all Glycine watch: the AIRMAN. The AIRMAN was a TRUE 24 hour watch favored by both military and commercial pilots and was the choice of watches by many U.S. Air Force pilots during the Vietnam War. Glycine still makes several variants of the Airman including the Incursore, Combat, and Lagunare series
The first self-winding wristwatch was invented in 1923 by Englishman John Harwood and used a 180 Degree [half] ratchet mechanism that wound the mainspring in one direction only and would “bump” and hit a stop bridge each time. The constant banging of the weight began caused premature failure, even when springs were added as a shock absorber, it still caused damage. The “Bumper Automatic” was utilized up into the 1950’s .
First 360 Automatic
In 1930, Rolex, using the Hardwood Core, patented, and exclusively produced only for Rolex brands the first 360 degree bi-directional automatic movement. The Pendulum rotated 360 degrees; winding both ways.
THE WORLDS FIRST INDEPENDENTLY DESIGNED TRUE 360 DEGREE TWO WAY WINDING AUTOMATIC MOVEMENT AVAILABLE TO THE MARKET WAS PATENTED BY FELSA IN 1942. This amazing, beautiful, compact, durable 360 degree BI-directional – Dual Winding automatic movement was named . THE BIDYNATOR. Nearly every automatic that followed was based on the Bidynator. Additionally, most high end brands used the BYDYNATOR, The actual inclusion into watches had to wait in most circumstances until after WWII. Thus we see an explosion of automatic watches in the late 1940s to early 1950s. Brands using the Bidynator included the all the great top line manufacturers. including THE FIRST GLYCINE AIRMAN LINE,.
THE FIRST TRUE PILOTS WATCH
In 1929,Captain Philip Van Horn Weems of the U.S. Navy (1889-1979), designed a system for navigation along with a Second Setting Watch watch that used a rotating exterior bezel or center dial with minutes/seconds chapter ring to synchronize the watch to the second using the radio time signal without adjusting the hands, This design incorporated a second “locking” crown that allowed the user to lock down the rotating bezel at the precise timing on the bezel. Captain Philip Van Horn Weems designed the “Weems System of Navigation” in 1927 – the year Lindbergh crossed the Atlantic. His “system” employed a modified sextant taking two “shots” of the sun, allied to an accurate time reading from his “Second Setting Watch”, followed by making reference to the tables in the Line of Positions book. (The Line of Position book provided extensive charts with PRE-calculated positions; allowing a pilot to look up the positions quickly and easily, instead of performing the complicated calculations himself.)
PRECISION FLYING DEPENDED ON LITERAL SECONDS, A few seconds off at air speeds and over great distances could prove dangerous, if not fatal. The Weems system, along with his invention of the Second Setting Watch, manufactured by Longines, enabled pilots and navigators to read truly accurate time directly from the watch face during an era when chronometrical precision was costly and rare. In 1929, in partnership with Longines, Weems registered a patent for this design. Longines produced the original “WEEMS” with locking crown at 2 position and added then larger model with locking crown at 4 position., [the Weems came in two sizes. one the same size of the decade later U.S. GOV MIL WWII A-11 PILOTS WATCH]
THE SECOND PILOT DESIGNED WATCH FOR THE PILOT
Charles A. Lindbergh, a pupil of Weems, used the WEEMS concept as an additional feature in his Hour Angle Watch. This first “Hour Angle” watch, which was patented by Lindbergh, had a hand wound pocket watch movement inside of a huge case and an extra long leather strap for wearing over a thick flight jacket sleeve. The crown was oversized to facilitate winding while wearing gloves. Featuring a demarcated rotating bezel that allowed for the equation of time (the difference between a standardized 24-hour day and the fluctuating time of the Earth’s travel around the sun), it was an accurate time piece which calculated longitude. A rotating central disc on the dial allowed for the synchronization of the seconds without stopping the sweeping hand. And unique dial markings allowed a pilot to instantly tell his location by corresponding the time with the earth’s 360-degree rotation (the “hour angle’).
Both the bezel locking mechanism of Weems, and the use of an external bezel for flight by LINDBERGH with the added 24hr modified movements by HELBROS AND A FEW OTHERS IN 1942, offered Gylcine the opportunity to the Glycine Airman. Only a patent free hacking method was left to tackle.
THE FIRST US GOV MIL ISSUE PILOTS WATCH
THE VINTAGE USAAC A-7 WAS PRODUCED UTILIZING A LONGINES SILVER POCKET WATCH/STOP WATCH WITH A STANDARD INDUSTRY BUTTON IN CENTER OF CROWN FOR THE TIMING DEVICE. IT WAS, IN FACT. THE FIRST SIGNED US GOVERNMENT ISSUED PILOTS WATCH I AM AWARE OF, AN A-7 DESIGNATION AND “USARMY AC” ON CASE BACK-. YEAR MID 1930.
THE FIRST PRODUCTION TRUE 24 HOUR WATCHES 1940/50S.
GLYCINE WOULD UTILIZE THE TECHNOLOGY HAT WAS UTILIZED IN THE NON AUTOMATIC TRUE 24HR WATCHES LIKE THESE ABOVE FROM 1941 THROUGH 44 THROUGH 50/S. ABSOLUTE TRUE 24 HOUR MOVEMENTS UPDATED OFF THE SHELF MOVEMENTS THAT WOULD GAIN AUTOMATION IN THE EARLY 1950’S. ONLY THE HACKING METHOD HAD TO BE CONFIGURED. YET, PATENTS ON THE STANDARD HACK WATCHES WERE IN FORCE. THEY WERE PATENTED FOR THE A-11 WATCHES.
PRODUCED BY VARIOUS MAKERS, The A-11 FOR WWII AND THE A-17 FOR THE KOREAN WAR – WHICH HAD A 24HR RADIUM DIAL, WERE SPECIFIC PILOT’/NAVIGATOR WATCHES– THOUGH THE WATCH WOULD BE UTILIZED BY OTHER BRANCHES INCLUDING GROUND TROOPS.
THE A-11 HAD A PATENTED HACKING LEVER SIMILAR TO JUST ABOUT ALL STOP WATCHES MADE FROM LATE 1800 TO PRESENT DAY. WHEN THE BUTTON/CROWN IS PUSHED IN TO STOP A TIMER, A “HACK “LEVER BEGINS AN ACTION THAT RELEASES A FRICTION STOP LEVER INTO THE BALANCE WHEEL CAUSING THE BALANCE TO CEASE ROTATION UNTIL RELEASED BY PUSHING THE BUTTON/CROWN AGAIN OR PUSHING A SECONDARY BUTTON.
ONLY TIMERS SUCH AS THE WWII A-8 NAVIGATION 10SEC TIMER, THAT OSCILLATE. AT SUCH INCREDIBLE SPEED THAT ANY ABRUPT STOPPAGE COULD DAMAGE THE STAFF/BALANCE ARE WITHOUT A HACKING MECHANISM.
AN A-11 CANNOT BE “STOPPED”. AFTER TIMING AN EVENT, THE CROWN IS CLICKED DOWN THAT STOPS THE HANDS –WHILE THE MOVEMENT CONTINUES TO RUN,– AND WHEN CLICKED AGAIN, THE HANDS “FLYBACK” TO TDC..– THE MOVEMENT CONTINUES TO RUN.
IN FACT, THE BALANCE WILL CONTINUE TO WIZ UNTIL THE MAIN SPRING IS UNWOUND COMPLETELY. : HENCE THE NICK NAME “THE JITTERBUG” …
ON THE A-11/A-17, AS WELL AS WATCHES MADE FOR VIETNAM WAR, THE ACTION BEGAN BY PULLING THE CROWN WHICH THEN ACTIVATES THE HACK LEVER STOPPING THE BALANCE.. THE HACK ABILITY OF A WRIST WATCH ALLOWED ONE TO SET EXACT TIME, TO TIME AN EVENT, AND, MOST IMPORTANTLY, ALLOWED A GROUP OF FLIERS AND NAVIGATORS, GROUND FORCES, ALONG WITH COMMANDERS ON THE GROUND OR IN FAR OFF COMMAND POSTS, TO ALL HAVE EXACT TIME. YES, TO ALL SET THEIR TIME PIECES EXACTLY.
AN IMPORTANT FACT IS THAT ALL THESE HACKING WATCHES DID NOT HAVE A FLY BACK MECHANISM. A FLY BACK IS THE DEVICE THAT CAUSES THE SECOND HAND TO RETURN TO TDC [TOP DEAD CENTER UNDER 12/24] WHEN THE WATCH IS STOPPED. LIKE THAT OF CHRONOGRAPHS AND POCKET STOP WATCHES. .
SO, HACKING THE A-11/17 DID NOT MOVE THE SECOND HAND TO TOP DEAD CENTER, RATHER, IT SIMPLY SHUT IT DOWN SO ONE COULD TIME THEIR WATCHES. SO, YOU WOULD WAIT UNTIL THE SECOND HAND WAS AT TDC-UNDER 12 TO PULL THE CROWN FREEZING TIME WITH SECOND HAND AT 12. THEN SET IT INDIVIDUALLY, OR IN A GROUP EVENT, A GROUP OF PILOTS/NAVIGATORS COULD ALL “ZULU” THEIR WATCHES WHEN READYING FOR THEIR MISSION,
A COMMANDER ISSUES A ZULU COMMAND TO PILOTS & NAVIGATORS
THE GLYCINE AIRMAN
Glycine Airman 1953
Glycine launched the first legendary “Airman Watch” in December of ’53 by applying for a 24 hour bezel patent. The patent would be issued in May of 1956 with number [Swiss Pat] 314 050. The first Airman had a White dial, red numbered white date wheel with no hacking method.
In 1953 the first Airman AM/PM [on dial] model was issued with pencil hands and patent pending marks on case back. It did not have a hack mechanism, it had the red date and no magnifier.
FIRST Glycine Airman AM/PM is scarce, no hack mechanism, no hand tail-end on minute or hour hand,red numbered date wheel,
In 1954-56 the second model with a tail end minute hand [the minute hand had an extension] and the date magnifier was released.
NOTE 3- the hand tailIS A STATIONARY GMT HAND. BY UTILIZING THE 24 HOUR BEZEL, YOU CAN SET THE TIME OF, SAY, CALIFORNIAS WHILE MAIN TIME IS NEW YORK. YOU SIMPLY SET THE TAIL END OF HOUR HAND TO BEZEL TIME. AM OR PM. ONE O CLOCK NEWYORK, THE VIEW THE HOUR TAIL END FOR SECOND ZONE
All early Airmen had the below Felsa 692 Bidynator movement, though modified to 24 hour, and signed.
WHEELS CHANGED FROM 1 COMPLETE TURN EQUALING 12 HOURS TO ONE COMPLETE TURN EQUALS 24 HOURS –THIS WAS A SIMPLE HACK
1953 – 1960 (1) Felsa 692, Bidynator 23 jewels
[1 AND 2] ALL Airman with the Felsa 692, Bidynator 23 jewel movement have a similar method of marking case-backs with the letter ‘A’ and then digits. The markings in the first Felsa 692, Bidynator 23 jewel powered models do not appear in the case-backs of the later AS/ETA powered models
 The Schild AS caliber began after 1960 and have the inner case-back logo registered by Glycine as ‘perfection‘
HELP WITH DATING
The final evolution into the models that made the Airman Famous continue with the mechanical hack mechanism, changes in the 12 and 24 illuminated markers and the moving of the tail on the minute hand to the hour hand
In 1967 Glycine begins using “CROWN” logo and launched the “Combat”, “GMT” , ” Airman SST Chronograph ‘ and “Airman SST” and “Glycine Automatic Sport SST” in paying tribute to the Super Sonic Transport project, Boeing 2 707. These are quite easy to id as far as dating.
Major model changes can be as simple as changing a word. The white dial, red date Airman with automatic spelled in French as ‘Automatique’ on dial center above the “12” –a French influence possibly due to the Indochina War- and it’s tail-ended Minute hand finaly evolved after 1960 with ‘Automatique’ altered to the English word ‘Automatic’ and its long tail minute changed to a long tail hour hand [ready for USA and Vietnam?]
CROWNS TO MAGNIFIERS
A ‘cross hatched’ crown -though this was not available in all models.– appeared
DIALS & STYLES
the hand tail IS A STATIONARY GMT HAND. BY UTILIZING THE 24 HOUR BEZEL, YOU CAN SET THE TIME OF, SAY, CALIFORNIAS WHILE MAIN TIME IS NEW YORK. YOU SIMPLY SET THE TAIL END OF HOUR HAND TO BEZEL TIME. AM OR PM. ONE O CLOCK NEWYORK, THE VIEW THE HOUR TAIL END FOR SEOND ZONE
The modification of the hands began with the Airman Arrow Tale, First The Minute Hand Then The Hour Hand. As discussed, the Airmen from 1954 & 55 had a arrow tail on the minute hand. From 1956 onwards, the hour hand has the tail-end.
THE EVOLUTION OF THE AIRMAN HAND
AIRMAN SPECIAL ID
The 1960-67 Airmen utilized the A.Schild 1700/01E 17j movement
Some Airman models have a triangle hour indicator at 12 and 24, often what seems like the same models have hour markers at the odd hours, or positioned in the second/minute scale. The A.Schild 1701/02 caliber,17 jewel Glycine Airman Special from 1960-67 has dot hour markers at 12 and 24 hours
HACKING YOUR AIRMAN
The use of a method for “hacking” the Airman involved no major alterations to the mechanics of the movement other than the stem needing to be doubled channeled and room made for the Hacking Arm to connect to the stem. As explained above, hacking begins with the crown being pulled and a hacking lever being moved into a position where a BALANCE WHEEL device uses direct friction to stop it. Thereby the sweeps second hand stops along with the entire movement.The A-11 and A-17, the Seiko Dive 6105, the Westclox, The Elgin, Bulova, Waltham as well as the Benrus Vietnam US Military issued watches all involved this method of hacking. In fact I am not aware of any other method. ,
YET ON THE GLYCINE AIRMAN, THE HACKING FEATURE IS PROPRIETARY AND COMPLETELY UNIQUE. THERE IS A CURVED HACKING TOGGLE LEVER “ARM” WITH A WIRE AT TOP. THIS ARM IS ATTACHED WITH A SWIVEL PIN THROUGH THE MOVEMENT RING.
THE WIRE ATTACHED AT THE TOP OF THE HACKING ARM IS THREADED THROUGH A HOLE IN THE A MINIATURE HOLDING DEVICE IN THE DIAL BETWEEN THE 24 HR NUMBER [ 2 “WIRE” 4] AT THE TOP OF DIAL.
UTILIZING THE SAME TECHNIQUE OF ALL HACKING MOVEMENTS, THERE IS AN EXTRA DENTE/CHANNEL ON THE STEM [SHOWN ABOVE AND FURTHER DOWN — WHERE, IN THIS CASE –PUN!– CONTACTS THE LOWER END OF THE HACKING. ARM.
PULLING THE CROWN MOVES THE BOTTOM OF ARM TO THE RIGHT -HACKED- AND PUSHING THE CROWN IN MOVES THE LOWER PORTION OF THE ARM TO THE LEFT -NORMAL
WHEN THE SECOND HAND REACHES THE 24 HOUR POSITION IT STOPS THE HAND AND THUS YOU ARE AT TDC.
PUSH THE CROWN IN, THE TOP OF ARM MOVES RIGHT PULLING THE WIRE DOWN AND FREEING THE SWEEP SECOND HAND AND THE WATCH STARTS BACK UP.
YET THE MECHANICS THAT WERE DESIGNED WERE POORLY CONFIGURED SO THAT THE HACKING FEATURE IS USUALLY NON EXISTENT,.BROKEN OR DAMAGED IN MANY AIRMAN THAT SURVIVED. MUCH OF THE DAMAGE WAS FROM REPAIRS BEING CONDUCTED W/O KNOWLEDGE OF THE MECHANISMS. WITH THE AIRMAN THERE ARE FIVE DISTINCT PARTS THAT ARE DIFFICULT TO MAKE–THOUGH AN INTERNET SEARCH MAY REVEAL A FEW INDIVIDUALS WHOM MAY MAKE THE PARTS.
The Airman does not use the known hacking technology. Instead, it utilizes a “wire” system along with a movement ring.A dente/channel/groove is cut in the stem, and, just like all stems, this channel interacts with a setting lever. When crown is pulled a setting lever is moved allowing one to set time. When pushed back in the lever moves into a winding position. So using this basic existing system, the Airman utilizes a stem with an additional groove/channel cut. Then a “toggle” hacking arm is attached to the movement ring. At the end is an attached wire that goes through the dial;. note These parts cannot be replaced.
On a hacking watch, the addition of a hack lever performs the action of stopping the movement. On the Airman the extra stem groove/channel/dente interacts with the hack lever arm with a wire. This wire is attached to the top of the hacking toggle arm movement pinned to the inner movement case ring.
When you pull the crown it pushes the wire up into and through the dial at tdc – top dead center – of the 24 number stopping the sweep center hand and the entire movement.
As to the difference between the Airman and the old school military Hacking watches, one has to wait until the second hand reaches tdc before you pull the crown and set your time. . but, in real war, you can hack the watch at any time and time an event or perform other functions immediacy, while the Airman only hacks at 24 hours.means the old school hack is much more efficient in a combat situation.
This other factor is that the wire method can break down. This method of hacking has never, to my knowledge, been utilized in any other brand, it simply does not operate as efficiently or is it as durable as the simple hacking lever movement..
This mechanism was only utilized in the Glycine late ’50’s and ’60s in Airman and Combat lines. This means that spare wires and/or parts are limited at best. Additionally. the Felsa. Schild, ETA models have different cases with different case rings.
