The Squale 1521 Black Blasted Rubber is a professional automatic diver built around the historic 1521 case design, a shape closely associated with Squale’s long involvement in underwater watchmaking. Its 42mm sand-blasted 316L stainless steel case presents a purposeful tool-watch character while remaining relatively slim and wearable for everyday use. The matte finish reduces reflections and reinforces the watch’s utilitarian identity, reflecting classic dive watches of the late twentieth century.
Clean Diver Dial and Functional Layout
The black dial emphasises clarity and underwater legibility. Printed indices and bold hands are filled with Super-LumiNova, ensuring visibility in low-light and submerged conditions. A unidirectional rotating bezel with minute markings allows safe tracking of dive time, while the simple layout keeps the display immediately readable at a glance. The restrained design prioritises function over decoration, maintaining a traditional professional diving aesthetic.
Swiss Automatic Movement
Inside the watch operates the Swiss Sellita SW200-1 automatic movement. The calibre beats at 28,800 vibrations per hour and offers approximately 38 hours of power reserve, with automatic winding and hacking seconds for accurate setting. This proven mechanical movement is widely respected for reliability and serviceability, supporting the watch’s practical professional role.
Professional-Grade Construction
A flat sapphire crystal with anti-reflective coating protects the dial from scratches and preserves clarity. The screw-down crown and screw-in case back contribute to a substantial 500 metres (50 ATM) of water resistance, suitable for serious diving environments. The aluminium bezel insert and solid steel case construction further enhance durability during underwater use.
Rubber Strap and Wearability
The watch is fitted with a black rubber strap, chosen for flexibility, water resistance and comfort during extended wear. The 20mm strap integrates securely with the case and is appropriate for both diving equipment and daily use.
A Classic Swiss Tool Diver
The Squale 1521 Black Blasted Rubber combines heritage case design, dependable Swiss automatic mechanics and true professional water resistance. Its emphasis on clarity, durability and practicality makes it a traditional mechanical dive watch suited to both underwater activity and everyday wear.
