Squale SUB-37 Legend

Squale SUB-37 Legend – A Return to the Essence of the Dive Watch

With the SUB-37 Legend, Squale presents a timepiece that consciously focuses on the essentials: proportions, functionality, and character. Introduced in March 2026 in Geneva at the Time to Watches fair, this model symbolizes a return to the origins of professional dive watches.

Inspired by the instruments of diving’s golden era, the SUB-37 embodies a clear design philosophy: every line is deliberate, every detail functional. Instead of following trends, it consistently adheres to the tradition of true tool watches.

Compact Size, Authentic Proportions

With a case diameter of 37 mm, the SUB-37 is inspired by historic dive watches that were primarily designed for use – not for visual exaggeration. The result is a watch that wears comfortably while impressing with its authentic presence.

The case made of 316L stainless steel with a polished finish is complemented by a screw-down crown and a screw-down case back, further emphasizing its robustness. With a water resistance of 300 meters, the watch meets all the requirements of a professional diver.

Vintage Character with Modern Technology

The box-shaped sapphire crystal echoes the look of classic plexiglass crystals while combining modern durability and scratch resistance. This design not only provides an authentic vintage feel but also optimal legibility.

The matte black dial with printed indices and vintage logo is complemented by Super-LumiNova Old Radium, ensuring excellent readability even in challenging lighting conditions – both above and below water.

Functional Bezel for Real Missions

The unidirectional rotating bezel with 120 clicks is clearly structured and designed for maximum functionality. The curved insert made of K1 glass in glossy black adds depth and a high-quality look.

The luminous markers enable precise time measurement while diving and emphasize the instrumental character of the watch.

Proven Swiss Mechanics

Inside works a modified Sellita SW200-1 automatic movement without date function in the Elaboré quality grade. This reliable caliber stands for precision and durability, meeting the standards of a professional timepiece.

With a power reserve of approx. 38 to 41 hours and a frequency of 28,800 vibrations per hour (4 Hz), the movement offers stable and precise performance—both in everyday use and under demanding conditions.

Comfortable rubber strap

The SUB-37 is equipped with a high-quality Bonetto Cinturini rubber strap, made from Italian vulcanized rubber. The distinctive ladder design provides high comfort, flexibility, and durability.

The polished pin buckle completes the overall look and ensures a secure fit on the wrist.

A watch with history

Squale is one of the most traditional names in professional dive watches. Founded in 1959 in Neuchâtel, the brand quickly became an important supplier for numerous renowned manufacturers.

Between the 1960s and 1980s, Squale supplied cases and components for over 30 brands and equipped professional divers as well as military units. Names like Enzo Maiorca and Jacques Mayol exemplify the brand’s close connection to diving.

The SUB-37 continues this legacy as a modern interpretation of a classic tool watch.
