Strap for Artelier Jumping Hour Stainless Steel / Silver

The Oris Artelier 01 917 7702 4051-07 5 21 70FC features a lug width of 21 mm. This measurement is taken internally between the pins connecting the case to the spring bars. The 21 mm dimension is a specific size that requires dedicated artisanal straps, as it is not a common commercial standard like 20 mm or 22 mm.

For the Oris Artelier 01 917 7702 4051-07 5 21 70FC, we recommend alligator or vegetable-tanned calf leather, which enhance the formal character of the satin-finished steel case. If you prefer practicality, a robust canvas NATO maintains the classic profile. Rubber is ideal for daily wear and warm climates. Your choice should balance formal aesthetics with practical use.

Changing the strap on the Oris Artelier 01 917 7702 4051-07 5 21 70FC requires: 1) Obtain a spring bar tool from a watchmaker. 2) Place the watch on a stable surface. 3) Insert the flat tip of the tool into the spring bar hole and lift gently to free one side. 4) Repeat on the other side. 5) Install the new 21 mm strap, ensuring the spring bar clicks securely on both sides. We recommend this operation be performed by a professional watchmaker if you are inexperienced.

Yes, any strap with a 21 mm lug width is compatible with the Oris Artelier 01 917 7702 4051-07 5 21 70FC. We recommend artisanal straps with construction quality equivalent to the case: premium leather, handcrafted workmanship, and precise finishing. A generic or budget strap diminishes the aesthetic potential of this watch. On milanostraps.it you will find 21 mm straps designed specifically for watches of this calibre.

The lifespan of a leather strap depends on tanning method and usage patterns. A vegetable-tanned calf strap typically lasts 3–5 years with moderate daily wear, developing patina and visible character. Alligator endures 4–7 years thanks to the robustness of the skin structure. Rubber exceeds 10 years. Exposure to direct sunlight, salt water, and extreme humidity reduces longevity. Proper maintenance—occasional cleaning and protective storage—significantly extends strap life.
