FAQ

What is the lug width of the Breitling Chronomat 28 A72310101C1A1?

The Breitling Chronomat 28 A72310101C1A1 features a 14mm lug width. This is a less common size in the contemporary watch market. Before purchasing an aftermarket strap, it is advisable to confirm the measurement using a vernier calliper positioned between the lugs at their narrowest point, to ensure a precise fit without stressing the lug openings.

What is the best strap for the Breitling Chronomat 28 A72310101C1A1?

For the 28mm stainless steel case of the Chronomat 28, the most suitable materials are vegetable-tanned calfskin for everyday elegant wear, alligator leather for formal occasions, and rubber or NATO straps for a more sporting aesthetic. The ideal choice depends on use and dial colour: blue dials pair well with a mid-blue calfskin or a two-tone NATO, while white or ivory dials suit cognac or burgundy leather for a classic, timeless look.

How do you change the strap on a Breitling Chronomat 28?

The strap on the Chronomat 28 is secured to the lugs by spring bars. To remove it, insert a thin-tipped springbar tool into the lug hole to compress the spring bar and release the strap. Given the compact 14mm size, care should be taken to avoid scratching the case surfaces. If in doubt, a watchmaker or the Casati Milano atelier can carry out the strap change during a fitting appointment.

Are there aftermarket straps compatible with the Breitling Chronomat 28 A72310101C1A1?

Yes. Any strap with a standard 14mm spring bar attachment is compatible with the Breitling Chronomat 28 A72310101C1A1. Milano Straps offers a curated selection of handcrafted straps in this size, available in various materials and finishes. For a fully bespoke solution, the Casati Milano atelier produces made-to-measure straps with direct selection of leather and stitching thread colour.

How long does a leather strap for the Breitling Chronomat 28 last?

The lifespan of a leather strap depends on material quality, frequency of wear and maintenance. A good quality calfskin strap, with regular but non-intensive use, typically lasts 18 to 24 months. Shell cordovan and alligator, due to their denser fibre structure, can last 3 to 5 years while developing an attractive patina. All Casati Milano straps are covered by an 18-month warranty against manufacturing defects.
