The Squale 1521 Militaire Blasted is a professional Swiss automatic dive watch that reflects the brand’s long-standing connection to underwater exploration. Its 42mm bead-blasted stainless-steel case frames a matte black dial with large luminous hour markers and bold hands designed for immediate underwater readability. A uni-directional rotating dive bezel allows safe elapsed-time measurement, while the screw-down crown positioned at 4 o’clock improves wrist comfort and protects against impacts. The dial is protected by a scratch-resistant sapphire crystal, and the watch is typically paired with a durable rubber strap suited for aquatic use.
Founded in 1959, Squale built its reputation manufacturing professional dive-watch cases for major Swiss brands and supplying watches for serious divers. The company’s identity centres on practical underwater reliability rather than decorative luxury, and the 1521 collection represents its most historically significant platform, a design created specifically for functional diving performance and proven durability.
Automatic Movement & Accuracy
Inside the 1521 Militaire Blasted is a Swiss automatic movement Sellita SW200-1, beating at 28,800 vibrations per hour and offering approximately a 38-hour power reserve. The self-winding mechanism powers hours, minutes and central seconds, delivering stable mechanical timekeeping suitable for daily wear and extended use without batteries.
Professional Dive Construction
The solid stainless-steel case is engineered for serious water activity and provides 500-metre (50 ATM) water resistance. A screw-down crown and sealed caseback protect the movement from moisture and pressure, while the sapphire crystal resists scratches and glare. The matte bead-blasted finishing reduces reflections underwater, improving practicality for divers and outdoor environments.
Clear Underwater Legibility
Large luminous indices and hands maximise visibility in dark or murky conditions, and the high-contrast dial layout ensures the time can be read instantly at a glance. The uni-directional bezel allows divers to track immersion time safely, preventing accidental extension of recorded dive duration.
A Purpose-Built Tool Watch
The Squale 1521 Militaire Blasted is not designed as a dress watch but as a true instrument. Its deep water resistance, dependable Swiss automatic movement and heritage dive-case design make it ideal for swimming, diving and daily wear. Combining authentic professional-diver credentials with straightforward mechanical reliability, it serves as a practical everyday sports watch as well as a respected piece among dive-watch enthusiasts.
