Micro-rotor movements are aesthetically pleasing and Buren
was the first company to introduce them.
BURIN succeeded in making a very thin, very accurate automatic
movement by employing revolutionary mechanisms that functioned reasonably well in a
variety of different levels of execution and elaboration, IT BEING THE MICRO

THIS Buren powered Thin-O-Matic mades for an interesting, RARE
horological significant addition to any watch collection. The first ever micro-rotor
automatic watch movement was patented by Uhrenfabrik Büren A.G in the mid 50s.
Their planetary rotor automatic movement
was released in 1957 in the Super Slender line, it was one of the flattest
automatics of its time. It and its derivatives competed with the Universal Geneva
micro-rotor for thinnest automatic in the world for many years.
THEN CAME UNIVERSAL GENEVA POLEROUTER
A shortcut by some thousand kilometers from Europe
to California (USA) was implemented by the airline SAS (Scandinavian Airline System).
These new routes were over the North Pole. UNIVERSAL GENEVE Provided the crews with
automatic precision wrist-watches that were resistent against the strong magnetic field of
the polar region. tHEY WERE TITLED THE "POLEROUTER/POLAROUTER" FOR THE

watch. In the late 1950's a steel Polerouter costs as much as a Rolex Explorer. A
Polerouter Date in 18 k gold with a gold bracelet had nearly the same price as a
In 1957 SAS inaugurated the transpolar service Copenhagen-
Anchorage -Tokyo with the new Boeing DC-7 C. The flying time was reduced from 52 to 32
hours. By tying together the southern route and the polar route, SAS had earned the right
to put "First over the pole and around the world" over the door on its DC-7 C's.
But a new era was coming closer - the jet age. Very quickly the
new jets like the SE-210 Caravelle and the Douglas DC-8-33 replaced the older propeller
