Strap for Aquis Date 43 Stainless Steel / Grey / Bracelet

The Oris Aquis 01 733 7653 4158-07 8 26 01PEB features a 20mm lug width. This dimension, measured between the spring bars that attach the strap to the case, is the standard specification for 43mm diving watches and is compatible with any strap constructed to 20mm nominal width specifications.

For the Aquis, we recommend an alligator strap with vegetable tanning for sporty elegance, chrometan calf leather with crocodile grain for daily balance, or fluoroelastomeric rubber for intensive water use. The choice depends on primary use: calf leather offers maximum versatility, alligator elevates the overall aesthetic, rubber ensures practical durability.

Use a dedicated spring bar tool. Insert the flat blade into the slot beneath one of the spring bars, lift slightly until it disengages from the lug seat, remove the old strap. Position the new strap into the lug openings, align the spring bar and press until it clicks into place. Repeat on the second side. Verify visual symmetry of the strap relative to the case before wearing.

Yes, all straps with a 20mm lug width are compatible. Milanostraps offers a curated collection of leather, NATO, and rubber straps certified for 20mm sizing. It is essential to verify the nominal strap width before purchase to avoid dimensional incompatibility.

A chrometan calf or alligator strap, with routine maintenance and spring bar repairs as needed, maintains structural functionality for 18–24 months of daily wear. Longevity varies based on exposure to moisture, chlorine, and atmospheric elements. Casati Milano recommends an inspection every 12 months to verify stitching integrity and surface patina development.
