Frequently asked questions

What is the lug width of the Breitling Cockpit B1335812C679?

The Breitling Cockpit B1335812C679 features a lug width of 20mm. This measurement refers to the internal distance between the lugs where the strap is fitted. To ensure a precise fit without lateral play, always use a strap confirmed at 20mm and verify compatibility with the original spring bars.

What is the best strap for the Breitling Cockpit B1335812C679?

Given the bi-metallic case in yellow gold and stainless steel, the most suitable straps are vegetable-tanned alligator — prized for its grain definition and developing patina — or shell cordovan for a dense, lustrous surface. For a more sporting aesthetic, a high-grade rubber strap underscores the Cockpit's aviator heritage. A deployant clasp in gold or steel cohesively mirrors the case's dual material character.

How do I change the strap on the Breitling Cockpit B1335812C679?

To replace the strap, the spring bars securing it to the lugs must be removed using a curved-tip springbar tool inserted into the lateral slots on the lugs. Work on a soft surface to avoid scratching the case, paying particular attention to the gold surfaces. If you are unfamiliar with the procedure, a watchmaker or specialist atelier is recommended to preserve the case finishing.

Are there aftermarket straps compatible with the Breitling Cockpit B1335812C679?

Yes: any 20mm strap with standard spring bars is dimensionally compatible with the Breitling Cockpit B1335812C679. Milanostraps.it offers a curated selection of handcrafted 20mm straps in fine leathers and technical materials, produced by Casati Milano atelier with customisable finishing. Specifying the reference allows the craftsmen to optimise heel curvature and aesthetic alignment.

How long does a leather strap last on the Breitling Cockpit B1335812C679?

A high-quality handcrafted leather strap, properly maintained and rotated with other straps, typically lasts between two and four years of daily wear. Vegetable-tanned alligator tends to offer superior longevity due to fibre density and the protective patina it develops over time. Prolonged exposure to water, acidic perspiration and direct contact with perfume should be avoided. Casati Milano provides an 18-month guarantee against manufacturing defects.
