Strap for Artelier Date Diamonds 33 Stainless Steel - Diamond / Silver

The lug width is 17 millimetres. This is a non-standard measurement in the aftermarket strap industry, so compatibility must be verified directly with the manufacturer. Manufacturing tolerance is typically ±0.5mm, but for a stress-free fit, we recommend confirming the exact lug width with a digital calliper before purchase.

The Oris Artelier 33mm performs excellently with vegetable-tanned leather straps (brown, burgundy, black), structured alligator, or shell cordovan for maximum durability and aesthetic patina development. For a sporty yet formal solution, military-spec cotton NATO or FKM vulcanised rubber offer practicality and ease of cleaning. The unifying element must be the 17mm lug width.

The procedure requires two specific tools: a spring bar tool and a soft support surface (silicone mouse pad or folded tissue paper). Position the watch horizontally on the soft surface, lug side facing you. Insert the flat end of the spring bar tool into the spring bar slot and apply gentle upward pressure to compress the internal spring, then extract the pin from the case. Repeat for the other lug. Reverse the process to install the new strap. Never use screwdrivers or sharp objects that could scratch the steel.

Yes, provided the aftermarket manufacturer's declared lug width is genuinely 17mm. The aftermarket offers limited selection in this size, as 17mm falls outside principal ISO standards (16mm, 18mm, 20mm). We recommend verifying user reviews for fit and contacting the manufacturer directly regarding manufacturing tolerances. Casati Milano curates a selection of 17mm straps in vegetable leather and synthetics, tested for Artelier cases and movements.

A high-quality artisanal strap in vegetable-tanned leather typically lasts 3–5 years with daily wear, provided minimal maintenance: air-drying after water exposure, protection from direct heat and chemicals, and conditioning with vegetable balm every 12–18 months. Shell cordovan, owing to equine protein structure, can reach 7–10 years. Vegetable fibres progressively thin, and failure typically occurs at the maximum bend zone (lug side). Replacement is not a construction fault but a natural characteristic of organic material. Rubber or synthetic NATO straps have superior durability (8–12 years) but lack the organic patina of leather.
