Strap for Chronomat 44 Stainless Steel / Diamond / Blackeye Blue / Rubber

The lug width of the Breitling Chronomat B01 44 reference AB0110AA.C789.145S is 22mm. This measurement refers to the internal distance between the two lug terminals and determines compatibility with any aftermarket strap. It is advisable to verify the measurement with a calliper before purchasing.

The most suitable straps for the Chronomat B01 44 are full-grain perforated calf leather in a rally style to emphasise its sporting character, vegetable-tanned alligator for a formal register, and nylon NATO or rubber for intensive use. The choice depends on context and dial colour: cognac, tobacco and military green work particularly well on a black dial.

Changing the strap on the Chronomat B01 44 requires a fine-tipped springbar tool. Insert the tip into the dedicated slot on the springbar, compress the spring and slide the strap free from the lug. The operation can be performed without professional tools, but it is advisable to work on a soft surface to avoid scratching the case.

Yes, any 22mm strap with standard terminals is compatible with the Chronomat B01 44. Milanostraps.it offers a selection of Italian handcrafted straps designed for 22mm lugs, supplied with springbars. It is important to select straps with straight or slightly tapered ends suited to the lug geometry of this reference.

The lifespan of a leather strap depends on the quality of the tanning, the frequency of use and the level of care. A full-grain calf or vegetable-tanned alligator strap, kept away from prolonged water exposure and excessive perspiration, will typically last between two and four years. Milano Straps products carry an 18-month guarantee against manufacturing defects.
