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.
