In 1934 Omega introduced their famous Calibre T17 movement. This tonneau-shaped movement was remarkable at these time for performance and reliability. This watch measures 39.6 mm (lug to lug) x 22,4 mm. At that time it was worn by both genders. Amazingly after 86 years it is still a working timepiece and may perfectly fit on a modern wrist. The Omega logo is hardly visible but still there.
