Strap for Aquis Date 36.5 Stainless Steel / Seafoam Green / Rubber

The lug width of the Oris Aquis 01 733 7770 4157-07 4 18 67FC is 18mm. This measurement represents the horizontal distance between the two lugs of the case, where the strap is fitted. An 18mm lug width is ideal for European wrists of average size and perfectly balances the proportions of the 36.50mm case.

The most suitable strap depends on intended use. For professional contexts, we recommend alligator or shell cordovan in cognac or tobacco tones, paired with a stainless steel deployante clasp. For sports or nautical environments, a NATO canvas strap in charcoal grey or navy blue enhances functionality. For diving or water activities, vulcanised rubber offers maximum practicality and durability without aesthetic compromise.

Strap replacement on an Aquis is performed by extracting the spring bars from the lugs. Using a professional spring bar remover tool, insert the instrument into the gap between the strap and case, then apply gentle pressure to compress the internal spring and release the bar. Once both bars are extracted, the strap separates from the case. The operation requires care to avoid scratching the case; we recommend consulting a professional if in doubt.

Yes, all straps designed for an 18mm lug width are compatible with the Aquis 01 733 7770 4157-07 4 18 67FC. At milanostraps.it, there is a curated selection of straps in alligator, calf, shell cordovan, NATO and rubber, all certified for 18mm compatibility and ready for dispatch. It is advisable to verify the clasp type (pad or deployante) according to personal preference.

A high-quality leather strap (alligator, calf or shell cordovan) has an average lifespan of 3–5 years under daily use, depending on environmental factors, frequency of use and maintenance. Vegetable-tanned alligator tends to age more rapidly than shell cordovan, developing a characteristic grey patina. Vulcanised rubber has a longer lifespan (7–10 years) but requires regular cleaning to maintain elasticity. Annual oiling with specialist products significantly extends the life of the leather strap.
