The Squale 1521 PVD version 1521PVD.VO is a professional automatic diver that pairs classic Squale design with a dark, modern finish. Its 42mm black PVD-coated 316L stainless steel case offers a solid wrist presence while preserving the 1521’s ergonomic proportions and tool-watch heritage rooted in over four decades of dive watch evolution.

Black Diver Dial and Function
This variation features a striking black dial with printed Super-LumiNova baton and dot indices that support strong legibility under varied lighting conditions. The bold Super-LumiNova-filled hands include an orange minute hand for quick orientation a practical element for diving and everyday reading. A date window is placed at the 3 o’clock position, adding everyday utility without detracting from the utilitarian layout. 

Swiss Automatic Movement
At its core is the Swiss Sellita SW200-1 automatic movement, providing self-winding mechanical operation with a power reserve of approximately 38 hours. The movement includes hacking seconds for precise setting and is recognised for reliable performance and wide serviceability among Swiss automatic calibres.

Professional Build and Water Resistance
A unidirectional rotating bezel with a black aluminium insert surrounds the dial, enabling elapsed dive-time tracking. A screw-down crown and screw-in PVD-finished case back contribute to a robust 500 metres (50 ATM) water resistance rating, making the watch suitable for serious underwater use, including recreational and technical diving. Sapphire crystal with anti-scratch properties protects the dial and preserves clarity in demanding environments.

Black Rubber Strap and Wearability
The watch is supplied on a black rubber strap with a 20mm lug width and a pin-buckle closure, chosen for flexibility, comfort and water readiness. The strap pairs with the PVD case to create a cohesive monochrome aesthetic while offering comfortable all-day wear on land or underwater.
