Cyma Watersport Ref. 25310 5550 steel vintage wristwatch, circa 1940
A stainless steel rectangular wristwatch with two-tone dial
A super looking vintage wristwatch, this Cyma has a water-resistant type rectangular case. The case is made to the specifications of Swiss patent 189190 which was issued to Schmitz Frères & Co. S.A. in 1936. The patented design was licensed to a variety of different manufacturers, including Gallet, the latter marketing the design under the name ‘Clamshell’. Essentially, the design related to a two-part case with 4 screws fitted to the underside which clamped the upper and lower case components together; in conjunction with a synthetic crystal, which had a broad lip underneath the bezel and the use of a water-resistant capped winding crown, an impermeable seal was formed.
The silvered dial has bold black Arabic numerals which are separated from the black outer minute track by a mirror finished, silver foil frame. Cased in steel, the rectangular upper body has chamfers to the edges and the separate case back has a gentle curve to fit the contour of the wrist. In lovely overall condition, there is one case screw missing from the back but the case is firmly secured by the three remaining screws.
