Description
Introduced in the early 1980s, the Squale 1521 quickly became the brand’s flagship diver and a benchmark in professional watchmaking. Squale, founded in 1959, had already established itself as a supplier of high‑performance cases to brands like Blancpain and Doxa, and the 1521 was the culmination of decades of expertise. Its distinctive design — curved case, recessed crown, and minimalist dial — was purpose‑built for saturation diving and adopted by military and commercial divers worldwide. Over the years, the 1521 has remained virtually unchanged, a testament to its enduring functionality and cult status among enthusiasts. Today, it stands as both a heritage piece and a modern tool watch, bridging Squale’s pioneering past with its continued dedication to authentic, professional‑grade dive instruments.
