Strap for Artelier Date 40 Stainless Steel - Yellow Gold / Silver

The lug width (also called lug size or strap width) of the Oris Artelier 01 733 7591 4351-07 5 21 70FC is 21mm. This measurement represents the distance between the two strap attachment points on the case and is essential for ensuring compatibility. It is the classical standard for 40mm watches, corresponding to a proportional ratio established in traditional watchmaking.

The ideal strap depends on your usage and personal preference. For daily elegance, a vegetable-tanned calf leather in natural brown or cognac enhances the model's aesthetic purity. For versatility, a silk NATO offers durability and refined informality. For those seeking a stratified patina developing over time, alligator or shell cordovan represent the most enduring choices. Rubber remains the optimal option for intensive use and transitioning between environments.

The strap is replaced by means of spring bars that pass through the case lugs. Using a spring bar tool (an instrument with dual curved tips), you compress the bar on one side, releasing the old strap. Position the new strap by aligning the holes with the lugs and release the bar, which locks automatically. This is a straightforward operation but requires precision to avoid scratching the case.

Yes, absolutely. Any strap with a 21mm lug width is compatible. Artisanal aftermarket straps often offer superior quality compared to factory alternatives, featuring carefully selected materials and bespoke finishing. Always verify that the lug width is precisely 21mm and that the spring bars are of the correct length to prevent mechanical stress.

Durability depends on the tanning method and intensity of use. A vegetable-tanned calf strap, if subjected to daily wear, typically offers 2-3 years of service before the leather shows significant wear. Shell cordovan, owing to its superior fibre density, can last 4-5 years. Regular maintenance—gentle cleaning and light conditioning—extends the strap's lifespan considerably. High-quality artisanal straps age elegantly, developing character and patina rather than degrading.
