Squale 1521 Blue Ray Automatic Dive Watch
A classic Swiss professional dive watch with unmistakable vintage inspired proportions, the Squale 1521 Blue Ray combines the brand's long established dive watch heritage with a striking smoky blue sunray dial and polished stainless steel case.
This example is part of Squale's well known 1521 family and features a 42 mm 316L stainless steel case, black unidirectional dive bezel, sapphire crystal, and 500 meter factory water resistance. The polished case construction gives the watch a more refined appearance than the blasted versions of the 1521 while retaining the same substantial professional dive watch architecture. Squale
The smoky blue dial is the defining visual feature of the Blue Ray configuration. Depending on lighting, it shifts from deep navy to brighter metallic blue tones while maintaining excellent contrast with the luminous markers and hands. The simple three hand layout keeps the dial highly legible and preserves the purposeful character of the 1521 design.
Powering the watch is the Sellita SW200 1 Elaboré automatic movement, operating at 28,800 vibrations per hour with 26 jewels and approximately 38 hours of power reserve. The movement offers automatic winding, manual winding, and hacking seconds. Squale
The watch is currently fitted to an aftermarket rubber strap. No original Squale strap or bracelet is included. This example is offered in near mint pre owned condition, showing only light superficial scuffing consistent with careful previous wear. Packaging remains in mint overall condition.
