1957 Enicar Seapearl 600 (Ref. 100/61)

Many Enicar watches host the word ‘Ultrasonic’ beneath the iconic Saturn logo below the 12 o'clock. While the 'Ultrasonic' marker does not indicate a specific reference or style of Enicar, it is actually the name of a technological procedure which they began using in 1953 in their factory in Oensingen, a city located in northern Switzerland. The 'Ultrasonic' process was designed by the Federal Institute of Physics in Zurich. The method was used to clean watch movement parts before assembly, using ultrasonic waves. The institute then further enhanced the technology by formulating a special chemical coating, which was applied to each piece of the movement. The coating prevented lubrication from diffusing throughout, which kept the lubrication in its intended locations within the movement. This process added a significant lifespan to their watches, minimizing the owner's need to seek frequent watch service. This special lubrication process was one of Enicar's prized innovations.

In 1958, Bulova was producing a waterproof diver’s watch for the US Navy’s Experimental Diving Unit (EDU). While the Bulova was under development, the U.S. Navy performed official tests on the Rolex Submariner and the Blancpain Fifty Fathoms but interestingly the Enicar Seapearl 600 was also popular with U.S. Navy divers even though they were in (non-issued). So the U.S. Navy included the Seapearl 600 in the tests as well. there is a great article over at Worn & Wound that outlines this interesting history of the Enicar Seapearl 600, it's for sure worth a read!

The matte black dial is in excellent condition and has aged to show a very handsome vintage patina. The radium lume plots have taken on a charming sandy tan coloration and exhibit no degradation when inspected under U.V. light. The original radium hands match the dial nicely and show no degradation and the original and unique "Candlestick" sweep seconds hand also remains with the watch! 


None. The watch is keeping time perfectly, previous service history is unknown.
