Strap for Chronomat 47 GMT Stainless Steel / Blackeye Blue

The lug width is 24mm. This is the standard distance measured between the attachment pins on the case. All straps compatible with this width will fit your Chronomat B01 44 correctly. To verify, use a digital calliper and measure the space between the two lateral pins.

It depends on usage and aesthetic preferences. Alligator or shell cordovan offer elegance and longevity, ideal for formal occasions. Vegetable-tanned calf combines solidity and refinement for daily wear. FKM rubber straps maintain the instrument soul of the chronograph. NATO straps guarantee versatility and quick-change practicality.

The Chronomat B01 44 uses a deployant buckle (usually supplied with the original strap). Position the watch with the lugs facing upward, locate the two pins that hold the strap inserted in the lugs, gently push each pin downward with a thin tool (spring bar tool), remove the old strap and replace it with a new one of the same lug width (24mm).

Yes, absolutely. Any strap with 24mm lug width is physically compatible with the Chronomat B01 44. High-quality artisanal straps, such as those available on milanostraps.it, maintain the required technical specifications and often offer superior materials and finishes compared to original equipment.

An alligator or shell cordovan strap, with regular care (drying after water contact, avoiding prolonged sun exposure), typically lasts 5–8 years of daily wear. Vegetable-tanned calf resists for 3–5 years. Patina and wear marks are normal and add character. FKM rubber straps last 2–4 years before losing elasticity and will need replacing.
