The 1930s and early 1940s were an exploratory time for watch manufacturers as is evidenced by the great diversity of case designs during this important period of the development of the wristwatch. Presented here is a wonderful example from Cyma, a Swiss watch manufacturer founded in 1862, housed in an oversized, water-resistant steel case that is wonderfully preserved.

The massive lugs are well defined and crisp, and on the underside, have four screws embedded to attach to the case. This two-piece so-called “clamshell” case was granted the Patent number 189190, based on its design. The side of the case has a lovely satin brushed finish, free of flaws with no signs of imperfections.

Furthermore, the eye catching gold and white colored printing of the tachometer and the outer telemeter scales contrast perfectly with the deep black dial surface, enhancing the character of an already interesting collectors’ timepiece.
