Strap for Aquis Date Calibre 400 41.5 Stainless Steel / Green / Rubber

The Oris Aquis 01 400 7769 4157-07 4 features a standard lug width of 22mm. This measurement represents the distance between the two horizontal lugs protruding from the case. To verify compatibility with a new strap, measure the internal gap between these lugs: it must precisely match 22mm to ensure a secure fit and correct articulation at the wrist.

The Oris Aquis, being a versatile Swiss diver, accommodates different strap materials depending on usage context. For intensive marine environments, a rubber strap offers complete waterproofing and immediate cleaning capability. For a more refined appearance, vegetable-tanned Tuscan leather develops a rich patina and resists saltwater. A heavyweight canvas NATO fabric provides the optimal compromise between practicality and aesthetics, maintaining maximum comfort in warm climates.

To change the strap whilst maintaining case integrity, remove the original strap by extracting the horizontal lugs using a spring bar tool (1.5mm specific tool). Align the new strap holes with the case lugs, then reinsert the pins with firm, uniform pressure until the locking click is heard. Verify the strap is secure by gently pulling both sides. Avoid forcing pins or using improvised tools, which risk scratching the ceramic case.

Yes, all aftermarket straps with a 22mm lug width are compatible with this Oris Aquis. It is essential to verify that the strap accommodates standard 1.5mm diameter pins and that its total length (from upper to lower pin) is sufficient for the case geometry, typically between 120-130mm. Artisanal straps in vegetable-tanned leather or premium rubber offer superior quality compared to generic solutions, ensuring greater durability and comfort.

The lifespan of a leather strap depends on intensity of use and exposure to external agents. High-quality vegetable-tanned Tuscan leather, worn daily without repeated immersion, maintains structural integrity for 3-5 years. Frequent exposure to saltwater, chlorine or intense perspiration reduces lifespan to 1.5-2 years, as leather absorbs moisture and deteriorates more rapidly. Rubber or NATO fabric straps, lacking absorption properties, have theoretically unlimited longevity but require periodic hygiene maintenance.
