Squale 1521 Green Ray Automatic Green Dial Rubber Strap Men's Watch 1521PROFGR.HT

The Squale 1521 Green Ray Rubber traces its origins to the historic case developed by Charles Von Büren in the 1960s, a design that has become synonymous with the brand’s diving heritage. Crafted from polished 316L stainless steel, the case measures 42mm in diameter, 48mm from lug to lug and 12.5mm thick, striking a balance between robust proportions and everyday wearability. The distinctive Green Ray dial sits beneath a flat sapphire crystal with an anti-reflective coating, revealing smoky green tones that shift with changing light. Printed hour markers and hands filled with Super-LumiNova C3 ensure clear legibility both above and below the surface, while the unidirectional rotating bezel features an aluminium insert with a sixty-minute diving scale.

Swiss Automatic Movement

At the heart of the watch is the Swiss-made Sellita SW200-1 automatic movement in Elaboré grade. Beating at 28,800 vibrations per hour and equipped with 26 jewels, the calibre provides approximately 38 hours of power reserve while supporting both hacking and hand-winding functions. A screw-down crown and solid screw-in caseback contribute to the watch’s impressive water resistance of 500 metres, reinforcing its credentials as a serious diving instrument. Combining reliable Swiss engineering with a design that has remained largely unchanged for decades, the movement reflects Squale’s longstanding focus on professional diving watches.

Rubber Strap

The 1521 Green Ray is fitted with a black rubber strap designed to withstand demanding conditions while providing comfort on the wrist. Measuring 20mm wide and secured by a stainless steel pin buckle, the strap complements the rich green dial and purpose-built character of the watch. The combination of the polished case and durable rubber strap allows the 1521 to transition easily from underwater use to everyday wear.

The Squale 1521 Signature

One of the defining features of the 1521 collection is its crown positioned at 4 o’clock, a practical solution originally developed to reduce pressure against the wrist and minimise the risk of accidental impacts while diving. Combined with the historic Von Büren case profile, this distinctive layout has become one of Squale’s most recognisable design signatures and has remained a core element of the collection for more than half a century.

The Green Ray model introduces a fumé dial finish that transitions from a vivid emerald centre to darker outer edges, creating a dynamic appearance that changes throughout the day. Alongside its exceptional 500-metre water resistance and enduring case design, the 1521 Green Ray Rubber retains the professional tool-watch character that has made the Squale 1521 one of the brand’s most celebrated collections.
