Strap for Artix Chronograph Stainless Steel / Silver

The lug width of the Oris Artix measures exactly 21 millimetres. This measurement, also indicated by the "21" in the reference 01 674 7644 4051-07 5 22 80FC, represents the internal distance between the two lug ears of the case. It is essential to verify this specification before purchasing an aftermarket strap, as an incompatible lug width would result in improper fitment.

For the Artix, we recommend three primary options: an alligator or vegetable-tanned calf strap for a classical and elegant approach; a NATO in structured rubber for sporting situations or humid climates; shell cordovan for those seeking a rare material and noble patina development over time. The choice depends on your intended use and personal philosophy regarding natural material ageing. All straps must feature a 21-millimetre lug width.

Strap replacement requires two tools: a spring bar tool and a clean work surface. Position the watch with the dial facing downwards, insert the pointed end of the lever into the access hole of the spring bar and gently lift until the bar disengages. Remove the old strap, align the new strap with the case lugs, reposition the spring bar ensuring it clicks securely on both sides. Repeat on the opposite lug. If you are uncertain, you may request assistance at the Casati Milano atelier.

Any strap with a 21-millimetre lug width is compatible with this model. Milanostraps.it offers a specialised collection of 21mm straps in artisanal materials: full-grain leather, cotton and rubber NATO straps, vulcanised rubber, alligator leather, and shell cordovan. Each strap is selected for superior construction quality and wear resistance—essential characteristics for a technical watch such as the Artix.

Durability depends on material type, tanning method, and frequency of wear. A vegetable-tanned calf strap used daily typically maintains structural integrity for 3-5 years before replacement is recommended. Shell cordovan, owing to superior fibre density, may last 5-7 years. Alligator straps fall in the mid-to-high range at 4-6 years. In arid climates, longevity increases. Cotton or rubber NATO straps are essentially permanent. Best practice is to rotate straps to distribute wear—a strategy particularly recommended for technical watches such as yours.
