FAQ

What is the lug width of the Breitling Cockpit B1335812A598?

The lug width of the Breitling Cockpit B1335812A598 is 20mm. This measurement is taken between the two case lugs using a digital calliper or a millimetre strip positioned transversally, and corresponds to the strap width at the point where it meets the case.

What is the best strap for the Breitling Cockpit B1335812A598?

Given the bi-metal yellow gold and stainless steel case of the Cockpit B1335812A598, the most suitable materials are alligator in cognac or tobacco tones, which complement the warmth of the yellow gold, or vegetable-tanned calf leather for everyday wear that develops a natural patina over time. Vulcanised rubber is recommended for sporting use or prolonged exposure to moisture.

How do you change the strap on a Breitling Cockpit B1335812A598?

The strap on the Breitling Cockpit B1335812A598 is replaced using a fine-tipped springbar tool. By pressing the ends of the spring bars between the lugs, they retract and release the strap. The operation requires no specialist tools and can be carried out independently, provided care is taken not to scratch the gold-plated lugs.

Are there aftermarket straps compatible with the Breitling Cockpit B1335812A598?

Yes, any strap with a 20mm lug width is compatible with the Breitling Cockpit B1335812A598, provided the ends are straight or slightly curved. Milanostraps.it offers a selection of handcrafted leather, rubber and NATO straps specifically sized for this measurement, with bespoke options available through the Casati Milano atelier.

How long does a leather strap last on a Breitling Cockpit B1335812A598?

The lifespan of a leather strap depends on the material, frequency of use, and exposure to perspiration and moisture. A quality handcrafted alligator or calf leather strap, with proper care and rotation, can last between three and seven years. Shell cordovan straps tend to age particularly well due to the density of the fibres. Casati Milano provides an 18-month guarantee against manufacturing defects.
