FAQ
What is the lug width of the Breitling Chronomat 40 GMT A32398C11C1A1?
The lug width of the Breitling Chronomat 40 GMT (ref. A32398C11C1A1) is 20 mm. This measurement should be taken with a digital calliper between the inner walls of the lugs on the underside of the case to ensure accurate compatibility with aftermarket straps.
What is the best strap for the Breitling Chronomat 40 GMT?
For the Chronomat 40 GMT, a square-scale alligator strap in black or navy complements the instrument-grade character of the watch. For everyday wear, a vegetable-tanned calf leather strap develops a distinguished patina over time. NATO nylon and FKM rubber straps are ideal for travel and active use.
How do you change the strap on the Breitling Chronomat 40 GMT?
The strap is secured by springbars which can be released using a dedicated springbar tool. Insert the tool between the lug and the strap end, compress the spring, and slide the strap out. It is advisable to work on a soft surface to avoid scratching the stainless steel case.
Are there aftermarket straps compatible with the Breitling Chronomat 40 GMT A32398C11C1A1?
Yes. Any 20 mm strap with a straight or slightly tapered end is compatible with the Chronomat 40 GMT. Milanostraps offers a curated selection of handcrafted leather, rubber and nylon straps in 20 mm, available with deployant clasps or pin buckles in stainless steel.
How long does a leather strap last on a Breitling Chronomat 40 GMT?
Longevity depends on the material and frequency of use. A quality calf leather strap, when properly maintained with leather conditioner and rotated regularly, typically lasts two to three years. A high-grade alligator strap can exceed five years. Casati Milano straps carry an 18-month production defect guarantee.
