Squale SUB-37 Legend Review: A Classic Dive Watch with Modern Appeal (2026)

Squale's SUB-37 Legend: A Masterclass in Dive Watch Minimalism

In the often-crowded world of dive watches, where brands constantly vie for attention with ever-larger cases and more complex features, Squale has taken a decidedly different, and in my opinion, far more compelling path with their new SUB-37 Legend. It’s a watch that whispers rather than shouts, a deliberate return to the core principles that made dive watches essential tools in the first place. What makes this particularly fascinating is that Squale, a brand with a rich heritage dating back to 1959, is renowned for its robust, professional-grade dive instruments. To see them embrace such a compact and elegantly simple design feels like a thoughtful, almost philosophical statement about what a true tool watch should be.

The Allure of Compactness

The 37mm stainless steel case of the SUB-37 Legend is, quite frankly, a breath of fresh air. In an era where 42mm and larger is the norm, this smaller dimension immediately signals a different intention. Personally, I think this size is a game-changer for so many wrist sizes that have been historically underserved by the dive watch market. It harks back to a time when watches were designed for function and comfort, not just to make a visual statement. The 11.2mm thickness further enhances this sense of understated wearability, ensuring it slips easily under a cuff, which is something many larger dive watches struggle with. The box-shaped sapphire crystal, mimicking vintage plexiglass, adds a wonderful tactile and visual dimension that feels both authentic and incredibly charming.

Legibility: The Unsung Hero

One thing that immediately stands out is the dial's exemplary legibility. Squale has opted for a matte black dial adorned with indices that are crisp and clear, outlined in white and filled with Super-LumiNova Old Radium. This vintage-toned lume is a detail I find especially appealing; it’s not just about brightness, but about evoking a sense of history and craftsmanship. The no-date configuration is a brilliant choice here, preserving the dial's perfect symmetry and reinforcing its purpose as a pure time-telling instrument. In my opinion, the addition of a date window can sometimes clutter a dial and detract from its primary function. The sword-shaped hands and the distinctive lollipop seconds hand also benefit from the lume treatment, ensuring that readability remains paramount, even in the most challenging low-light conditions. This focus on fundamental legibility is what truly elevates the SUB-37 Legend from a mere accessory to a reliable tool.

Pragmatism at its Core

Beneath the elegant exterior lies the workhorse Sellita SW200-1 automatic movement. While some might crave a more exotic in-house calibre, I believe this is precisely the right choice for a watch with a tool-watch vocation. It's a reliable, proven movement that is easily serviceable, aligning perfectly with the SUB-37's ethos of practical functionality. The 38-hour power reserve is standard, and while not groundbreaking, it’s perfectly adequate for a watch that will likely be worn regularly. What this pragmatic choice also achieves, and it's a significant point, is keeping the price accessible. At EUR 1,650, it offers tremendous value for a Swiss-made dive watch with this level of heritage and thoughtful design.

The Enduring Appeal of Purpose-Built Design

The SUB-37 Legend, with its 300m water resistance and robust construction, is clearly built for purpose. The unidirectional bezel, with its clean design and luminous markings, is precisely what you need for timing dives, without any unnecessary frippery. It's a testament to Squale's understanding of what a diver truly requires. Wearing this watch, from my perspective, is about appreciating the quiet confidence of a tool that does its job exceptionally well. It reminds us that true innovation often lies not in adding more, but in perfecting the essentials. This watch doesn't just tell time; it tells a story of diving heritage and intelligent design, making it a compelling proposition for anyone who values substance over spectacle. What this really suggests is a growing appreciation for watches that prioritize wearability and functionality, a trend I hope continues to flourish.
