The Original Size of Serious Diving

The Squale SUB-37 Legend embodies the philosophy that a true tool watch is not designed to be noticed, but rather designed to endure. As a historic specialist in professional dive equipment, Squale has long been trusted by generations of divers who value reliability, legibility, and authentic design over fleeting fashion trends. The SUB-37 channels this heritage with compact, purposeful proportions, featuring a 37mm case that honors the original size of serious diving. With a water resistance rating of 300 meters, it stands as a serious, no-nonsense instrument engineered for real underwater timing, proving that a smaller form factor does not compromise on capability or robustness.

Constructed from durable 316L stainless steel with a polished finish, the watch measures 11mm in thickness and has a lug-to-lug length of 45mm, ensuring it wears comfortably on a wide range of wrists. The case is fortified with a screw-in caseback and a screw-in crown to maintain its integrity against the pressure of deep dives. At the heart of the SUB-37 beats the Swiss Made Sellita SW200-1 automatic movement. This reliable caliber operates at a frequency of 28,800 vibrations per hour, contains 26 jewels, and offers a 38-hour power reserve, delivering the precise performance expected of a professional-grade timepiece.

Visual clarity is paramount in this design, achieved through a classic box-shaped sapphire crystal with an antireflective coating that protects the dial while adding a vintage aesthetic. The black dial features printed indexes and hands treated with Super-LumiNova Old Radium, a material that provides a warm, retro glow for exceptional readability in low-light underwater environments. Surrounding the dial is a monodirectional bezel with a K1 mineral crystal insert, a critical safety feature that allows divers to track elapsed time accurately. Each watch is individually numbered, adding a layer of exclusivity and distinct authenticity to the piece.

Completing the package is a premium Italian Bonetto rubber strap. Straps like these are favored in the diving community for their resistance to salt water, temperature extremes, and general wear. The strap features a 20 mm lug width that tapers to a 16 mm buckle, ensuring a secure and comfortable fit during long dives.

The Squale SUB-37 Legend is more than just a watch; it is a functional tribute to diving history that prioritizes purpose and endurance, offering a timeless blend of vintage charm and modern technical reliability for those who demand a tool that works when it matters most.
