The Sub-39 models were created to celebrate the sixty-year history of the Squale brand. Introduced in 2019, the anniversary model was presented in a limited edition of just 150 pieces. To date, the Sub-39 collection features a wide range of watches, all inspired by the past.

The structure of the case was designed for the use of a particular glass, neither flat nor rounded but box shaped. The structure of this glass is flat at the base, where it is recessed, and then continues with a slight curvature until it stops and returns to being flat for the entire surface where it covers the dial. This structure, typically used in the past on plexiglass glass, is reproduced here faithful to the original. The only difference compared to the past is the material with which it is made, that is sapphire, highly more resistant than plexiglass.

The case of the “Sub-39” collection is inspired by the prototype of an old Squale, found in the archives of Charles Von Büren, made in the 1960s but never gone into production. This watch, still in perfect working order, has the typical dimensions of the time, in fact the diameter is 34 millimeters. Even today, the case of the Sub-39 collection has maintained the same characteristics as the original watch, but with different dimensions.

This Sub-39 with the GMT function comes on the steel (non-sel) bracelet, other combinations possible.
