Strap for Chronomat 41

The Breitling Chronomat B01 41 AB014012F554428X has a lug width of 20 mm. This measurement is taken with a digital calliper across the inner distance between the two lugs at the strap attachment point, not across the outer case width.

For the stainless steel Chronomat B01 41, a vegetable-tanned alligator strap is recommended for formal wear, whilst a high-density vulcanised rubber strap suits aquatic or intensive sport use. A ballistic nylon NATO strap emphasises the model's aviation heritage. The correct width in all cases is 20 mm.

The Chronomat B01 41 uses standard 20 mm spring bars. Using a spring bar tool, compress each bar inward to release the strap from the lugs. The process takes approximately two minutes and does not require a watchmaker, provided care is taken not to scratch the lug surfaces.

Yes. The Chronomat B01 41 AB014012F554428X uses standard 20 mm spring bars, making it fully compatible with quality aftermarket straps. Milanostraps.it offers a curated range of handcrafted leather, rubber, and NATO straps specifically matched to this 20 mm lug width.

Longevity depends on leather quality and daily conditions. A vegetable-tanned alligator strap, conditioned periodically with neutral wax and kept away from prolonged water exposure, will maintain its structural and aesthetic integrity for 3 to 5 years. Casati Milano straps carry an 18-month warranty against manufacturing defects.
