Strap for Chronospace Automatic

The lug width of the Breitling Chronospace A2336035G718167A is 24mm. This measurement is fixed and corresponds to the width of the case between the inner edges of the lugs. Any aftermarket strap must comply with this dimension within a tolerance of ±0.5mm to ensure correct fit without structural play or excessive tension on the spring bars.

The ideal strap depends on intended use. For actual flight operations: 1000D nylon NATO in grey-green, waterproof and quick-change. For formal elegance: anthracite or black alligator with matched thread, which responds to the geometric rigour of the dial. For natural patina development: vegetable-tanned leather, burnished brown calf, which gains character over time. In all cases, the 24mm lug width must remain constant.

Strap change requires minimal tools: a fine spring bar tool or watchmaker's screwdriver, maximum length 1.5mm. Position the case at 3 and 9 o'clock, insert the tip beneath the internal elastic pin of the lug, push downward to release the upper keeper, extract the strap. Repeat at the opposite lug. Reinstalling the new strap follows the reverse path. Do not force: lugs are stainless steel, elastic pins are tempered spring steel.

Yes, any strap with a 24mm lug width is structurally compatible. Online, personalised straps are available in leather, shell cordovan, alligator, and technical textiles. We advise against straps exceeding 80-90 grammes in mass, which would alter the balance on an already substantial 46mm case. Always verify that the lugs are free of knurling that could scratch the case.

Durability depends on tanning method and usage. Vegetable-tanned leather: 3-5 years in daily wear before visible signs of wear at the fold. Treated alligator: 5-7 years with maintenance (conditioning every 12-18 months). Shell cordovan: 2-3 years before requiring polish, but develops crystalline patina. Nylon NATO: 4-6 years without colour degradation under normal conditions. Perspiration, humidity fluctuations and UV exposure accelerate ageing of any leather. Store the strap away from direct light when unworn.
