Strap for Oris Artelier 01 733 7591 6351

The lug width of the 01 733 7591 6351 is 21mm. This measurement represents the internal space between the two spring bars that attach the strap to the case. Before purchasing a replacement strap, always verify this dimension by unscrewing the caseback or consulting an authorised watchmaker.

For this model, we recommend Mississippi alligator in cognac tone, which complements the warm hues of the rose gold case beautifully. Italian vegetable-tanned calf leather represents a more formal alternative, whilst a quality jacquard NATO offers everyday versatility. Your choice should reflect your intended use: dress occasions favour alligator, smart-casual suits calf, and relaxed wear suits NATO construction.

Changing the strap requires a spring bar tool (approximately 2-3mm wide). Position the tool under the elastic spring holding the lug pin, apply gentle upward pressure to compress the spring, and carefully extract the pin. Repeat for the second pin. When installing the new strap, ensure both pins sit fully within their grooves and the spring mechanism is freely functional. If uncertain, entrust this task to a qualified watchmaker.

Yes, provided the strap is correctly sized at 21mm lug width and crafted from premium materials. An artisanal vegetable-tanned Italian leather strap guarantees both technical compatibility and aesthetic longevity. Verify that the strap's attachment mechanism—whether passant or deployante clasp—is robust, and that the leather width at the case junction maintains visual proportion.

Lifespan varies according to wearing intensity and climate exposure. A quality alligator strap with vegetable tanning typically serves 3-5 years under regular wear; calf leather of 2-3mm thickness offers similar durability. Continuous exposure to perspiration, humidity, and sunlight accelerates deterioration. Rotating between multiple straps extends the lifespan of each significantly.
