Strap for B55 Exospace Titanium / Black / TwinPro Grey / Folding

The lug width of the Breitling Exospace B55 Connected is 24 mm. This dimension is measured from the inner left edge to the inner right edge of the case at the point where the strap springs attach. Always verify this measurement with a digital calliper before purchasing an aftermarket strap, as variations of ±0.5 mm cause lateral play or mounting failure.

The optimal choice depends on use case. For instrumental flight and tactical situations, an FKM rubber strap is superior: waterproof, thermostable up to +80 °C, with zero moisture absorption. For formal or civilian wear, African alligator with vegetable tanning offers recognised aesthetics and decade-long durability. Vegetable-tanned calf provides evolving patina over time. A titanium deployante clasp maintains case coherence and reduces overall wrist weight.

The Breitling Exospace uses quick-release springs. Position the watch on a soft surface, locate the tiny lateral levers beneath the case (obverse and reverse), press toward the centre with a blunt tool (never pointed), and the spring retracts allowing strap removal. Proceed identically with the new strap, ensuring the lug shoulders seat fully in the case recesses before releasing the lever.

Yes, any strap with 24 mm lugs and quick-release springs is compatible. However, Breitling recommends certified straps to guarantee water resistance and aesthetic coherence. Artisan straps from specialised suppliers (with titanium or steel deployante) maintain aeronautical functionality. Always verify spring diameter (typically 1.5 mm) and spring length (approximately 11 mm for the B55).

An alligator strap with vegetable tanning resists approximately 5–7 years under daily use with ordinary maintenance (monthly cleaning, conditioning every 12 months). Vegetable-tanned calf has similar lifespan if not exposed to prolonged moisture. FKM rubber lasts 8–10 years. Longevity drops sharply if the strap remains exposed to direct UV, constant humidity, or extreme temperatures.
