Frequently asked questions

What is the lug width of the Breitling Chronomat B01 44 HB0110AE.A698.375H?

The lug width of the Breitling Chronomat B01 44 reference HB0110AE.A698.375H is 22mm. This measurement corresponds to the internal distance between the two case lugs and is the standard to use when selecting any compatible replacement strap.

What is the best strap for the Breitling Chronomat B01 44 in rose gold?

For a rose gold case measuring 44mm, an alligator strap in cognac or havana brown offers the best balance between elegance and tonal continuity. Alternatively, vegetable-tanned calf leather develops an authentic patina over time, whilst vulcanised rubber is the ideal choice for everyday sporting use. The lug width to use is 22mm.

How do you change the strap on a Breitling Chronomat B01 44?

The strap on the Chronomat B01 44 is removed using a fine-tipped spring bar tool, levering out the spring bar that connects the strap to the case lugs. The operation takes approximately two minutes per side and can be carried out without sending the watch to an authorised service centre. It is advisable to work on a soft surface to avoid scratching the rose gold case.

Are there aftermarket straps compatible with the Breitling Chronomat B01 44 HB0110AE.A698.375H?

Yes, any strap with a 22mm lug width is compatible with the Breitling Chronomat B01 44. Milano Straps offers a selection of handcrafted leather, rubber and NATO straps specifically sized for this model, with Italian craftsmanship and personalisation options available at the Casati Milano atelier.

How long does a leather strap last on a Breitling Chronomat B01 44?

The lifespan of a leather strap depends on the quality of the hide, frequency of use, and exposure to perspiration and moisture. A quality artisan alligator or vegetable-tanned calf leather strap, with regular alternated use, has an average lifespan of 2–4 years. Rotating between two straps and using a suitable leather conditioner will significantly extend its longevity.
