Strap for Oris Aquis 01 733 7653 4155

The lug width of the 01 733 7653 4155 is 26mm. This measurement refers to the distance between the spring bar attachment points on the sides of the case. A compatible strap must have a body thickness of 24mm to 26mm, as the lugs adapt within the construction tolerances of the spring bar itself.

Given the tool-watch character of this 300-metre model, vulcanised rubber straps are the most coherent choice: chemical resistance, total waterproofing, extended comfort. For vintage aesthetics, vegetable-tanned leather develops naturally over time. For occasional diving, a NATO textile strap offers chromatic versatility and quick-change practicality.

The procedure requires a spring bar removal tool: position the tip under the spring bar end, apply inward pressure towards the case and lift simultaneously. The spring will retract, allowing removal of the worn strap. Fitting the new strap follows the reverse procedure: thread the lug ends into the spring bar holes and press until you feel the locking click. Work with controlled movements to avoid scratching the case.

Yes, compatibility is guaranteed by any strap of 26mm lug width, provided the build quality is certified. Artisanal leather straps (alligator, shell cordovan, vegetable-tanned calf) and FKM rubber straps are fully compatible and do not affect the movement warranty, as the strap is not a warranted component.

A quality artisanal calf strap with vegetable tanning lasts an average of 3–5 years of daily wear, depending on humidity and direct sun exposure. An alligator strap, thanks to the fibrous structure of the scales, can extend the lifespan to 6–7 years. A vulcanised rubber strap lasts 4–6 years before losing elasticity and adherence. Regular maintenance (gentle cleaning, complete drying after salt water contact) significantly prolongs working life.
