Strap for Artix Complication Stainless Steel / Black

The lug width of the Oris Artix 01 915 7643 4034-07 5 21 81FC is 21 millimetres. This measurement represents the distance between the two internal lugs of the case and is the historical standard for aviation watches. To verify it with precision, use a digital caliper measuring the distance between the case's lug attachment points.

The best strap depends on your intended use and personal preferences. For a classic aviator aesthetic, we recommend alligator leather with vegetable tanning, which directly references the historical straps from the 1940s–50s era. For everyday versatility, a vegetable-tanned cognac calf leather offers both elegance and durability. For maritime environments or high-humidity conditions, vulcanized rubber is the superior technical choice. All these materials are available in 21mm from MilanoStraps in artisanal versions.

Strap replacement is carried out using the spring bars located at the ends of the lugs. Using a dedicated tool (pin remover or spring bar tool), gently push inward on the spring contained within the bar to release the strap from the lug. Remove the old strap and insert the new one by reversing the procedure. If you are unfamiliar with the operation, consult a professional watchmaker.

Yes, the Oris Artix 01 915 7643 4034-07 5 21 81FC is fully compatible with any quality aftermarket strap that features a 21-millimetre lug width. MilanoStraps manufactures artisanal straps in calf leather, alligator, shell cordovan, NATO, and rubber, all in the 21mm size, tested to offer perfect compatibility without requiring any forced adjustments.

The lifespan of a leather strap depends on the quality of the tanning and the intensity of use. A vegetable-tanned calf leather strap, such as those produced artisanally by MilanoStraps, typically offers a lifespan of 3–5 years of daily wear before requiring replacement. Alligator or shell cordovan straps, owing to the inherent robustness of the fibre, typically reach 6–8 years. Keeping the strap dry and clean significantly extends its serviceable life.
