The Chronospace EB601010.C945.158S, seen from the bench

The Breitling Chronospace Evo B60 Mariner Blue (ref. EB601010.C945.158S) is a professional chronograph instrument designed for military and civilian pilots. The 43 mm grade 2 titanium case houses the Caliber B60 SuperQuartz movement, COSC-certified, featuring high-frequency foudroyante, rattrapante and flyback functions—a combination rarely found outside advanced military watchmaking. The 22 mm lug width accommodates standard watch straps and pairs with various materials available in our atelier, from vegetable-tanned Tuscan calf leather to polished box calf.

Frequently asked questions

What is the lug width of the Breitling Chronospace EB601010.C945.158S?

The lug width of the Breitling Chronospace EB601010.C945.158S is 22mm. This measurement is taken between the two lugs using a digital calliper and indicates the correct strap width at the point of contact with the case.

What is the best strap for the Breitling Chronospace EB601010.C945.158S?

For the titanium-cased Chronospace, a Tuscan vegetable-tanned calf leather strap with a fine grain is the most balanced choice: it complements the professional character of the watch and develops a natural patina over time. Porosus alligator suits more formal occasions, while vulcanised rubber is preferable in sporting or humid environments.

How do I change the strap on the Breitling Chronospace EB601010.C945.158S?

The strap is removed using a spring bar tool, either flat-blade or forked, by pressing the spring bar between the lug and the strap. It is advisable to work on a protective surface to avoid scratching the titanium case. Original 22mm spring bars can be reused if they remain in good condition.

Are there aftermarket straps compatible with the Breitling Chronospace EB601010.C945.158S?

Yes. Any strap with a 22mm lug width is compatible with the Chronospace EB601010.C945.158S. Milano Straps offers a selection of handcrafted leather, alligator, NATO and rubber straps made to order, with stitching and finishing options tailored to the dial and case finish.

How long does a leather strap last on a Breitling Chronospace?

A quality leather strap typically lasts between two and four years with daily wear, depending on exposure to perspiration, humidity and mechanical stress. Vegetable-tanned leather straps of adequate thickness (3.5–4mm) with a calf leather lining offer better longevity. A deployant clasp reduces daily stress and significantly extends the life of the strap.
