Refined Versatility

Textured Calfskin — Natural Depth

A strap that adapts — without ever losing its character.
Crafted from softly textured calfskin, this deep walnut tone adds tactility and a slightly more grounded feel to the 3940. It sits between refinement and ease — equally at home with tailoring or something more relaxed.
There’s a quiet richness here, reminiscent of worn leather, travel, and time well spent. Slim, supple, and comfortable at 1.9 mm, it becomes part of the watch — and part of you.

Designed for the 3940 - Perfect 18/14 Taper

This strap is specifically designed for watches like the Patek Philippe 3940, featuring a refined 18 mm to 14 mm taper.
This elegant reduction is essential for the proportions of classic perpetual calendars, enhancing the slim profile and allowing the watch to sit perfectly balanced on the wrist.
The 14 mm buckle width ensures full compatibility with original Patek Philippe buckles as well as folding clasps.
Please note: when using a folding clasp, the strap may wear slightly longer on very small wrists due to the fixed clasp position.

Quick Release Spring Bars

Quick Release - Change Without Risk

This strap can be fitted with quick release spring bars, allowing you to change straps easily without the need for tools.
By sliding the small integrated lever, the spring bar retracts smoothly, making installation and removal quick and controlled.
This reduces the risk of scratches on delicate gold cases - a practical and thoughtful solution, also used by Patek Philippe on many of their modern straps.
Effortless, safe, and perfectly aligned with high-end watchmaking.
