Strap for Artelier Jumping Hour Stainless Steel / Silver

This model features a lug width of precisely 21 millimetres. This is an unconventional measurement compared to common standards (18 or 20 mm), selected by Oris to maintain proportional balance between the 40.50 mm case and the strap structure. This technical specification makes it essential to seek straps specifically designed for 21 mm.

The model responds exceptionally to alligator or crocodile leather straps with vegetable tanning, where the natural ageing of the leather dialogues with the case patina. A neutral-toned Calf leather (hazelnut, ice grey) preserves essential elegance. For controlled sportiness, a NATO strap in grey or black amplifies versatility without compromising aesthetic authority. The choice depends on intended use and personal colour preference.

The technical procedure remains standard: position the watch in a strap removal tool (or on a stable surface), locate the spring bar attachment that connects the strap to the case, and use a spring bar tool to extract the pin. Once removed, the old strap releases from the lug. Insert the new strap (ensuring it is precisely 21 mm), aligning the holes, and reintroduce the spring bar carefully. Verify that the pin is fully secured before wearing the watch again.

Yes, provided the strap has been specifically engineered for 21 mm lug width. Quality artisanal straps often offer accurate compatibility with this measurement. Always verify that the width corresponding to the spring bars is genuinely 21 mm, not estimated on standard sizes. Specialist brands such as Milano Straps produce customisable 21 mm straps, guaranteeing precise mechanical fit and construction quality consistent with the timepiece.

Longevity depends on leather quality, frequency of use, and environmental conditions. A vegetable-tanned alligator or shell cordovan strap on a daily-worn watch retains structure and aesthetics for 3–5 years, developing a desirable patina. Softer calf leather may require replacement within 2–3 years. Constant exposure to moisture, perspiration, and UV rays accelerates deterioration. Regular maintenance (gentle cleaning, drying, occasional conditioning) significantly extends strap lifespan.
