Davosa Watch Ternos Medium 16619620. Davosa watches are reviving the spirit of the 1960s with the Sixties edition of its popular Ternos divers watch. In this edition, the Swiss manufacturer of high quality mechanical watches focuses not only on materials and design, but also on how the watch feels on the wrist, in a bid to revive the carefree decade during which freedom in lifestyle and fashion became so important. The case of the Ternos Sixties is made entirely from corrosion resistant 316L stainless steel. It is shaped like a lens, and fits snugly onto the wrist. The screw down back domes several millimetres, concealing a robust Swiss DAV 3021 automatic movement. The dial is protected by a domed glass, a typical characteristic of 1960s watch design. A uni rotational, aluminium bezel underscores the vintage look.
