Henry Moser

Esculape

A very fine and rare vintage wristwatch with jumping centre seconds for medical professionals

With most mechanical watches the second hand moves smoothly between the seconds.The hand usually moves with every vibration of the balance, which, for a watch with 18,000 half beats per hour this is five times per second. A dead seconds function requires an extra mechanism to reduce this frequency to once per second to be displayed on the dial. The calibre was created by Chézard, a subsidiary of Ebauches SA.
This timepiece is in very good condition, with only very slight signs of age on the case. The two-colour dial with a darker outer area has a concentric guilloche pattern which brings out the gold arrowhead indexes to great effect.
