Strap for Chronospace Evo B60 Mariner Blue / Military

The lug width of the Breitling Chronospace EB601010.C945.109W is 22 mm. This can be confirmed by measuring the internal distance between the two lugs with a calliper, or by consulting the official Breitling technical specification sheet for this reference.

For a 43 mm titanium case with an aeronautical character, the most suitable straps are: vegetable-tanned calf leather in dark brown or navy for refined daily wear, Hornback alligator in anthracite for formal occasions, and a ballistic nylon NATO in grey or military green for outdoor use. In all cases, the 22 mm lug width must be respected for a correct fit at the lugs.

To replace the strap on a Breitling Chronospace, use a spring bar tool to remove the spring bars from the lugs. Rest the case on a soft surface to avoid scratching the titanium. Insert the tip of the tool into the lateral notch of the spring bar, compress it, and slide it out of the lug. Repeat on both sides, then fit the new 22 mm strap in reverse order.

Yes. Any strap with a 22 mm lug width is compatible with the Breitling Chronospace EB601010.C945.109W, provided the spring bars have a standard diameter (1.8 mm) and appropriate length for the lug gap. Milanostraps.it offers a curated selection of handcrafted straps in leather, alligator, NATO and rubber, all available in 22 mm for this model.

The lifespan of a leather strap depends on the material, tanning method and conditions of use. A quality vegetable-tanned calf strap, cared for properly and kept away from prolonged moisture, typically lasts 2–4 years. Vegetable-tanned alligator can last 4–6 years or more. All Casati Milano straps from Milanostraps.it carry an 18-month guarantee against manufacturing defects.
