Weems Watch

In 1927 Philip Van Horn Weems, a U.S. Navy officer, devised a watch with a settable second hand that could be easily corrected to the second using radio time signals. That made it more useful for air navigation than even precision maritime chronometers and was the beginning of the aviator's "hack" watch. Longines produced a number of 'Weems Watch' variantions in 1920s-1940s (plus later limited editions, incl. present-day Heritage series).

No Logo

A very striking advert for Philips of Eindhoven, issued for the Swiss market in the 1930s. Unusually neither the sets nor the advert use the famous Philips 'wavy line' logo. The design, using photo montage elements, is very of its period.

1931 Reverso Watch

The idea of Reverso originated from a challenge by an unnamed Polo player in 1930, when the player allegedly shown Cesar De Trey his watch with a broken glass (no sapphire crystal then) after a Polo game in India.
De Trey entrusted the work to a French engineer Alfred Chauvot, who started work almost immediately and on 4th March 1931, supposedly under the instruction of Cesar De Trey, Chauvot applied for the patent of "a watch capable of sliding into its base and of turning completely on its axis".
By November 31st, Cesar De Trey has together with business partner Jacques David LeCoultre (both were close business associates even prior to this) established the company, "Specialites Horlogeres" which merged with Jaeger (managed by Gustav Delage) six years later to become Jaeger-LeCoultre.
