Strap for Artelier Skeleton 40 Stainless Steel

The lug width of the Oris Artelier 01 734 7721 4051-07 5 21 65FC is 21mm. This dimension corresponds to the internal diameter of the case's metal lugs, namely the available space between the shoulder pieces where the strap is inserted. It is essential to respect this tolerance to ensure mechanical compatibility and strap stability during wear.

For the Artelier 01 734 7721 4051-07 5 21 65FC, four categories of 21mm straps are recommended: shell cordovan, which develops a deep patina over time; vegetable-tanned calf leather, for those who prioritise environmental sustainability; NATO fabric, for those seeking ease of replacement and chromatic versatility; vulcanised rubber with grain texture, to emphasise the technical character of the skeletonised movement. The choice depends on your use context and the aesthetic relationship you wish to establish with your timepiece.

Changing the strap on the Artelier requires the use of a specific tool for removing the spring bars. These pins, located at the ends of the lugs, keep the strap in place. You must gently compress the pin towards the inside of the case to release one end of the strap, then extract the pin and repeat the operation on the other side. Installation of the new strap follows the reverse procedure. We recommend operating with care to avoid scratching the case or the pins themselves.

Yes, any aftermarket strap with 21mm lug width is compatible with the Oris Artelier 01 734 7721 4051-07 5 21 65FC. However, it is essential to verify that the strap width corresponds exactly to 21mm: an undersized strap would cause unwanted lateral movements; an oversized one could damage the lug finish. The bespoke straps from milanostraps.it are crafted with precise construction tolerances to guarantee absolute compatibility.

The lifespan of a leather strap depends on the quality of the raw material, the type of tanning (vegetable or chrome), frequency of use, and environmental conditions. A shell cordovan strap in vegetable tanning, used daily, maintains structural functionality for 3-5 years before replacement is necessary for aesthetic reasons; calf leather offers similar longevity. Exposure to excessive humidity, prolonged direct sunlight, and perspiration accelerate ageing. A NATO fabric strap in robust material guarantees superior durability, up to 7-10 years with regular maintenance. Vulcanised rubber offers maximum resistance, up to 15 years if protected from extreme thermal stress.
