The Ernest Borel Chronograph from the 1950s is a remarkable piece of horological history—an oversized waterproof chronograph featuring the legendary Valjoux 23 movement, celebrated for its precision and durability. This timepiece not only embodies technical excellence but also stands as a tribute to the pioneering spirit of Ernest Borel, one of the most influential names in Swiss case manufacturing.
Its steel case, measuring a generous 36mm, presents the classic aesthetic of the era with rounded chronograph pushers and a screw-down caseback—a hallmark of Borel’s innovation in waterproofing. The watch carries the weight and confidence of mid-century design while remaining wearable and elegant by modern standards.

It’s a piece that wears its age beautifully—a watch with character, as only the finest vintage chronographs can be.

Completing the package is a handmade Belgian leather strap in rich brown, crafted from premium-grade leather for both comfort and a refined finish. The strap adds a contemporary touch while respecting the watch’s vintage elegance.
