Strap for Chronomat 40 GMT Six Nations Italy

The Breitling Chronomat 40 GMT A323981C1C1A1 has a lug width of 20mm. This measurement is taken between the two lugs at the point where the spring bar is inserted. All straps with a 20mm attachment are compatible with this reference.

For the steel Chronomat 40 GMT, the most coherent choices are: hornback alligator in navy or anthracite for a sport-elegant look, shell cordovan in burgundy for a bespoke touch, and vegetable-tanned calfskin for everyday wear. A ballistic nylon NATO strap suits those who prioritise lightness and practicality.

Strap replacement requires a spring bar tool to remove the spring bars from the lugs. The Chronomat 40 lugs are accessible and allow the operation without particular difficulty. Work on a soft surface to protect the case and use 1.5mm diameter spring bars, 20mm in length.

Yes. The Breitling Chronomat 40 GMT A323981C1C1A1 uses standard 20mm lugs, making it compatible with the full range of quality aftermarket straps. milanostraps.it offers a selection of handcrafted straps in 20mm, compatible with this reference, available in leather, nylon and technical materials.

Longevity depends on leather quality and usage. A high-grade alligator or shell cordovan strap, properly maintained with nourishing cream and kept away from heat sources, can last 3 to 5 years with regular use. Vegetable-tanned calfskin has a similar lifespan but requires more care regarding moisture exposure. Casati Milano straps carry an 18-month warranty against manufacturing defects.
