Schatz Ship's Clock Tuning fork Mechanism c1960s
Significance A "Lectromarin" Schatz ship's clock with a tuning fork mechanism c1960s. Tuning fork clocks were made in a brief period in the 1960s after transistors were developed but superseded by more accurate and simpler quartz clocks. No bell, which is unusual for a ship's clock, presumably too complicated with this mechanism, as with the battery balance-wheel clocks. Rare, as few were made but not particularly valuable. The term "Lectromarin" was used for both tuning fork and battery balance wheel clocks by Schatz. Discussion The look of a traditional ship's clock but no bell for the ship's watch. Tuning forks were used in desk, wall and ship's clocks, as well as in wristwatches. Accurate, battery-operated but delicate and a little noisy with an audible hum. From eBay USA. The face of the clock with a tuning fork symbol. The tuning fork mechanism by Schartz. The green and red coils keep the tuning fork oscillating.
