Series 21

Compact, discreet, understatement

The series 21.50.12 and 21.50.14 are meant for watch connoisseurs and lovers with narrower wrist, who value classic shapes without compromising on practicality. The housing engages in the design elements of the 50's, rectangular chronograph pushers and compact diameter.

Series 21

Our Serie 21 features the 1950s design elements, a rectangular chronograph pusher and a compact case diameter. However, this watch is completely suitable for everyday wear as it is water resistant up to 10 bars and features a scratch-proof sapphire crystal on the front side.

This compact classic is powered by an automatic Swiss chronograph movement that is finely decorated and clearly visible through the watch’s glass back.
