FAQ
What is the lug width of the Breitling Chronomat 32 U77310101A1U1?
The lug width of the Breitling Chronomat 32 U77310101A1U1 is 16mm. This measurement should be verified with a digital calliper between the two lower lugs of the case before purchasing any aftermarket strap.
What is the best strap for the Breitling Chronomat 32 U77310101A1U1?
For the Chronomat 32 in steel and red gold, alligator leather in cognac or burgundy tones complements the bimetallic case beautifully. Vegetable-tanned calf leather is the most versatile option for daily wear, while shell cordovan offers superior longevity and a distinctive texture. For sport or water use, vulcanised rubber in black or anthracite grey is the most practical solution.
How do you change the strap on a Breitling Chronomat 32 U77310101A1U1?
The strap on the Chronomat 32 is replaced using a spring bar tool. Insert the tip of the tool into the lateral notch of the lug, compress the spring bar, and slide out the strap. The spring bar diameter is the standard 1.5mm. It is advisable to carry out this operation on a soft surface to avoid scratching the bimetallic case.

It is essential to confirm that the lug width is exactly 16mm and that the buckle width is 14mm to maintain correct proportions.

How long does a leather strap last on a Breitling Chronomat 32?
The longevity of a leather strap depends on the material and frequency of use. A vegetable-tanned calf strap typically lasts 2–3 years with daily wear.
