Paul Wyler presented his first 16 and 19-line precision movements to the public in 1927. The particularity of these was the ICAFLEX balance wheel, which was legendary at the time.

The Wyler Incaflex balance wheel is protected along its diameter by two curved, elastic arms, which absorb any shocks to the balance wheel.

In addition to producing his own calibres, Wyler also modified movements of other large-scale producers and sold these on to other watch companies. In some cases, the basic calibre was changed so much that the movements should actually be considered as Wyler calibres.

In 1937 the WYLER INTRODUCED THE WATER-RESISTANT     watch that was not fitted with the conventional soft gaskets.

The crystal was pressed in between the edge of the case and a pressed or screwed bezel, the gap between the winding shaft and the watch case was sealed hydraulically by fitting the winding shaft and bushing together, in the same material, to 1/500mm.
