Strap for Altitude Officier Small Seconds

The Altitude Officer 101OBJX features a lug width of 20mm. This measurement represents the distance between the two straight lugs on the case where the strap is inserted. It is a precise constructive specification that ensures compatibility with all 20mm artisanal straps available in our catalogue.

The optimal strap depends on intended use and aesthetic preference. For formal elegance, we recommend genuine alligator in black or calf leather in vegetable tanning, in cognac brown tones. For daily versatility, a navy blue or anthracite grey NATO offers practicality without visual compromise. Grey rubber is ideal for sports or aquatic environments, creating contemporary contrast with the rose gold case.

Strap replacement is performed by removing the lug pins (spring bars). Using a dedicated tool or small screwdriver, apply gentle pressure to the pin to release the internal spring, allowing extraction of the old strap. Insert the new strap—ensuring its width is exactly 20mm—and reinsert the pins until you hear the locking click. The operation takes minutes and requires no specialist knowledge.

Yes, completely. Any strap with a 20mm lug width is compatible with the Altitude Officer. The critical factor is verifying the measurement before purchase. Undersized straps (18mm) may be too tight and cause friction; oversized straps (22mm) would be loose and compromise aesthetics. The 20mm standardisation permits frequent and creative substitutions without risk to the case.

Strap longevity depends on material, tanning method, and daily usage patterns. A high-quality vegetable-tanned calf strap, worn three to four times weekly, typically lasts 2-4 years before showing significant wear. Alligator, a more resilient material, can last 4-6 years. Longevity increases substantially by reducing exposure to water, perspiration, and direct sunlight. Many enthusiasts rotate multiple straps to extend individual lifespan and vary the watch's aesthetic character.
