Strap for Aquis Date Diamonds 41.5 Stainless Steel / Red / Bracelet

The lug width of this Aquis model is 21mm. This dimension is measured precisely between the two case lugs that serve as the rotation axis for the strap. It is essential to verify this measurement with a digital calliper before ordering an aftermarket strap, as even minor variations would result in an ill-fitting passant.

The ideal strap depends on the primary intended use. For daily elegance, a vegetable-tanned calf leather strap creates harmony with the satinised stainless steel case. For diving or humid environments, satinised rubber is the most practical solution. Waxed canvas NATO straps offer versatility and quick changes, whilst alligator represents the most refined choice for formal occasions. At Atelier Casati Milano, specialist consultation is available to determine which material best integrates with your aesthetic preferences and usage patterns.

The strap is changed by opening the spring bar that secures the lug pin within the case. Using a dedicated spring bar removal tool, position it on one of the two pins and apply gentle pressure to compress the internal spring. Once compressed, the pin slides out laterally. Repeat this operation on the other pin. To install the new strap, align the pin with the lug openings, position it and allow the spring to expand inside the case until you feel the securing click. Verify that both pins are properly seated.

Yes, the Oris Aquis 01 733 7766 4998-07 8 22 05PEB is fully compatible with any 21mm strap of appropriate construction quality. On milanostraps.it you will find a specialised collection of artisanal 21mm straps, from leather to rubber, selected for proportions and finishes that enhance the geometry of this model. All straps are tested for compatibility and available with customisation options.

Durability depends on construction quality and tanning type. A vegetable-tanned calf strap, worn daily in non-extreme environments, has an average lifespan of 3-5 years. Frequent exposure to salt water or humidity reduces this interval to 18-24 months. Shell cordovan, due to its superior molecular density, resists for an average of 5-7 years even under demanding conditions. Rubber offers maximum durability (7-10 years) but requires periodic treatment to maintain flexibility. A well-maintained strap, protected from direct sunlight and dried after accidental water contact, significantly extends its operational life.
