Strap for Chronomat 44 Stainless Steel / Silver / Bracelet

The lug width of the Breitling Chronomat B01 44 AB011011/G684/375A is 22mm. This measurement should be taken internally between the two lugs using a millimetre calliper, at the base of the case. This is the correct dimension to use when purchasing any compatible aftermarket strap.

The most suitable materials for the Chronomat B01 44 are hornback alligator in tobacco or dark brown, which enhances the depth of the dial, grained calf leather for a sport-elegant register, and vulcanised rubber for intensive use. Shell cordovan is the premium choice for those seeking an evolving patina over time. All options require a 22mm lug width.

To replace the strap on the Chronomat B01 44, you will need a fine-tipped spring bar tool or a watchmaker's screwdriver. Insert the tool into the spring bar slot, compress the bar and slide it out of the lug hole. Take care not to scratch the stainless steel case. The new 22mm strap is fitted by reversing the procedure.

Yes, the aftermarket offers a wide range of straps compatible with the Chronomat B01 44 AB011011/G684/375A, thanks to the standard 22mm lug width. Milano Straps offers a handcrafted selection in leather, NATO and rubber with a 22/20mm taper, fully compatible with the original lugs without any case modification.

The lifespan of a leather strap depends on the material, care and usage. A high-quality alligator or calf leather strap with vegetable tanning, kept away from water and excessive perspiration, can last between 2 and 5 years. Shell cordovan straps tend to last longer due to the density of the fibres. Milano Straps offers an 18-month guarantee against manufacturing defects.
