With a high beat movement, blue dial and being highly original, this Cyma Synchron automatic is bound to have wide appeal. Model reference 73-007-56.
HOW DO WE DATE THIS WATCH?
Cyma have been making watches since 1862, but in 1968 Cyma joined Ernest Borel and Doxa to make the Synchron group. Cyma was then sold on to a private investor in 1978, so this watch had to be made within this ten year period. Furthermore, the movement used in this watch was not launched until 1971, which further narrows the window. We have chosen the mid point between these parameters.
CONDITION
Mechancial wrist watches do not have sweep seconds hands – instead the second hand stutters around the dial, but on a standard 18,000 bph movement it stutters five times a second so looks like it sweeps. However if you double the beat rate to 36,000, the second hand stutters 10 times a second and therefore it looks twice as smooth, and few watches ever made run at higher than 36,000 bph. This watch also has Chronometre on the dial, meaning it met the higher criteria of timekeeping. We do not have any certificate to prove this but significantly the movement does have a serial number – a pre-requisite of getting a chronometer certificate – and micro screw adjustment. It is running very well. The movement itself is labeled a Synchron 73, but is actually an ETA 2826. That means this 21 jewel automatic with hacking and quick set date should be easy to have serviced in the future. The stainless steel case has a few marks but the graining is all visible. The dial is original and there is some deterioration around some of the hour markers. The leather strap is new, and could be swapped for a different colour if preferred.
This watch will be supplied with an original Cyma presentation box and our Certificate of Authenticity.
