Strap for Artelier Grande Lune Date Diamonds 36 Stainless Steel / Silver

The lug width of this Oris Artelier model is 18 millimetres. It is an aristocratic dimension, slightly below commercial standard (20, 22 or 24mm), which emphasises the compact proportions of the 36mm case. Correct measurement is performed with a digital calliper positioned between the lugs without compression of the metal.

The ideal strap depends on intended use. Alligator with vegetable tanning expresses pure formal elegance; natural calf leather offers daily versatility; a cotton and linen NATO permits a semi-sporty approach whilst maintaining sobriety; FKM rubber guarantees dimensional stability and humidity protection. The 18mm width requires craftsmanship in customising the spring bars.

The strap is changed by removing the spring bars that connect the strap to the case. Using a specialised tool (spring bar tool), push the bars inward, sliding them out from the lugs. Insert the new strap, aligning the holes with the spring bars, and press until both bars click into retention. Verify that both spring bars are fully seated before wearing the watch.

Yes, provided the strap has been manufactured or customised for the 18-millimetre lug width. Mass-market aftermarket straps, typically calibrated for 20, 22 or 24mm lugs, will not fit correctly. Engage specialist craftsmen who possess the expertise and instrumentation to shorten spring bars and buckles without compromising the structural integrity of the strap.

Longevity depends on material and usage. A quality leather strap with vegetable tanning, given appropriate care (avoiding prolonged water and heat exposure), typically lasts 3-5 years before requiring replacement or reconditioning. Alligator tends to last longer due to skin structure. FKM rubber offers greater longevity, exceeding 5-7 years without significant degradation. Rotating between multiple straps extends the life of each.
