Inset is the more simple spring fitted to protect the balance staff pivot on the dial side of the movement.

In the event of a shock the arm flexes to absorb the force, cushioning the pivots on the balance staff. Protection is provided by a thin steel arm mounted on top of the balance cock which houses the cap jewel for the balance staff. Rather than use one of the proprietary systems such as Incabloc or KIF, Cyma chose to develop their own and called it the “Cymaflex”. One thing to note is the shock system fitted to protect the balance staff in the event of a fall.

30L I wrote about recently, the Cyma still has chatons for the train wheels and an overall quality feel. Though not quite as finely finished as the Longines cal. 416 Ka., a straight forward time only calibre with a leisurely beat rate of 18,000 bph (in modern watches that has now increased to 28,800 bph or 6 bps for increased accuracy). The watch in this post was made during the 1950’s and is fitted with a Cyma cal. Though wristwatches were a large part of their business they were also known for producing alarm clocks, the most famous being the “Sonomatic” fitted with a 16 jewel movement which had an 8 day power reserve.Ĭyma are still in business today and you can see their current collection here (which includes some chronometer rated automatics… always a good sign!).

Popularity fuelled growth, and by 1929 they owned the largest watchmaking workshop in Europe, employing 2000 people, and producing 4000 timepieces per day. After the turn of the century, the company began to diversify into ultra-thin pocket watch calibres and inevitably into the production of wristwatches. One such watch was this Cyma Watersport.Ĭyma started producing timepieces in Le Locle, Switzerland in 1862, and during their first 40 years specialised in quality pocket watches, including both chronographs and minute repeater models. Every so often a watch comes across the bench that isn’t complicated or particularly popular with collectors, but has something about it.
