NOTES: Dial has a rare misprint of Depthomatic spelled Dephtomatic instead and only seen on a few examples thus far. Bernard Delmotte, chief diver on Cousteau's Calypso crew, used to wear this model and can been seen in photos this Nivada Depthomatic. Nivada Grenchen, located at the town of Grenchen, was a niche watchmaker that created several interesting watches. Perhaps the most well known Chronomaster chronograph. The Depthomatic was unique in that it could function as a depth measurement tool by using the Bourdon depth gauge tube. This is an instrument for measuring the pressure of gases or liquids, consisting of a semicircular or coiled, flexible metal tube attached to a gauge that records the degree to which the tube is straightened by the pressure of the gas or liquid inside. An interesting mechanism for that time period. This model is hardly seen for sale today and especially in this extremely well preserved condition. Furthermore, this rare misprint "dephtomatic" dial has only been observed a handful of times.
