Movado M90 mirror indexes

Movado M90 chronograph from the late 1930s, featuring a 33 mm stainless steel case with olive-shaped pushers and a large winding crown, characteristic of Movado chronograph production of the period. The watch has a two-tone silver dial with blue outer scales and an inner snail scale, mirror-finished indexes, two sub-dials, and a serpent-shaped chronograph hand on the minutes register. It is powered by the manual-wind Movado caliber M90 movement and is fitted with a period-correct bracelet.
