Strap for Aquis Date 43 Stainless Steel / Grey / Bracelet

The lug width of the Oris Aquis 01 733 7653 4157-07 8 26 01PEB is 26mm. This measurement, determining strap compatibility, is taken from the internal distance between the lug terminals. A 26mm strap ensures perfect balance with the 43mm case without gaps or structural tension.

For the Aquis, leather straps in alligator or calf with vegetable tanning are recommended for formal contexts, offering natural patina and aesthetic ageing. For intensive underwater use, FKM rubber straps provide waterproofing and salt resistance. Heavy cotton NATO straps represent the sports alternative, ideal for recreational diving. Choice depends on the desired balance between dress aesthetics and water-sports functionality.

Strap replacement requires extraction of the spring bar (perno) from the side lugs. Use a dedicated tool to gently press the spring bar from the opposite end of the lug, releasing the internal spring. Remove the previous strap lug and install the new one, repositioning the spring bar. Verify that the spring bar is fully seated and that both lugs are stable. Avoid direct hammering, which damages the spring bar and lug structure.

Yes, any strap with 26mm terminal lugs is compatible with the Aquis. Artisanal high-quality straps from specialised ateliers such as Milano Straps offer superior structural compatibility and construction quality compared to industrial straps. Always verify that the lugs are 26mm and that the spring bar is in good condition.

The lifespan of a vegetable-tanned leather strap depends on use and environment. Under normal conditions (dress wear, no diving), a quality artisanal strap lasts 3–5 years before replacement is needed. Frequent exposure to salt water and humidity accelerates wear. FKM rubber, conversely, resists 10–15 years under intensive underwater conditions. Leather ages aesthetically, developing natural patina appreciated by enthusiasts, whilst rubber maintains stable functional characteristics.
