A rare 1940s Tissot “Aqua Sport” featuring an unusual clip-on waterproof rectangular case and an attractive two-tone gilt dial.
This rare example features a clip-on rectangular waterproof case, a construction renowned for its excellent sealing properties and also found on Omega and Jaeger-LeCoultre models from the same era. The caseback is engraved with indications of its water-resistant, anti-magnetic, and shock-resistant properties, while the watch is powered by the Cal. 17.5, equipped with a shock-absorbing mechanism, making it a true vintage sports model.
The beautifully designed two-tone dial, produced using the gilt technique, is particularly impressive in its execution. Both the Tissot logo and “AQUASPORT” inscription are finished in gilt, reflecting the meticulous craftsmanship of the period.
Measuring 23mm across the case with a generous 19mm lug width, this model is relatively substantial for a rectangular watch while retaining a compact and beautifully balanced dial design. Its distinctive proportions and sophisticated styling give it a wonderful vintage character.
A particularly unusual and collectible Aqua Sport, distinguished by its rare rectangular waterproof configuration, in contrast to the predominantly round-cased examples more commonly encountered.
