FAQ
What is the lug width of the Breitling Chronomat 36 A10380101A2A1?
The lug width of the Breitling Chronomat 36 A10380101A2A1 is 20mm. This measurement is taken with a digital calliper positioned between the two lugs of the case, perpendicular to the longitudinal axis of the watch. It is the essential parameter for purchasing a compatible aftermarket strap.
What is the best strap for the Breitling Chronomat 36 A10380101A2A1?
For the Chronomat 36 A10380101A2A1, the choice depends on the context of use. Vegetable-tanned alligator leather is the most refined option for formal occasions; vegetable-tanned calf leather develops a natural patina over time for daily wear; a NATO nylon strap remains faithful to the model's aeronautical origins; vulcanised rubber is recommended for sports activities or water exposure. All these straps are available in 20mm lug width.
How do you change the strap on the Breitling Chronomat 36 A10380101A2A1?
To replace the strap on the Chronomat 36, a spring bar tool with a tapered tip is required. Insert the tip into the lug channel, compress the spring bar and slide the strap free from its seat. Care must be taken to avoid scratching the steel lugs: it is advisable to protect the case with masking tape during the replacement. The standard spring bar for this model is 20mm.
Are there aftermarket straps compatible with the Breitling Chronomat 36 A10380101A2A1?
Yes. Any strap with a 20mm lug width attachment is technically compatible with the Chronomat 36 A10380101A2A1. Milano Straps offers a selection of handcrafted straps in alligator, calf leather, shell cordovan and rubber, produced bespoke or available online, designed to integrate precisely with the case and lug geometry of the Chronomat.
How long does a leather strap last on the Breitling Chronomat 36 A10380101A2A1?
The longevity of a leather strap depends on the quality of the hide, the tanning process and daily use. A high-quality vegetable-tanned calf strap has an average lifespan of 2–4 years with regular wear; an alligator strap can exceed 5–7 years if properly maintained — kept away from prolonged water exposure, direct heat and alcohol-based fragrances. Casati Milano straps carry an 18-month guarantee against manufacturing defects.
