Strap for Aquis Big Day Date 45.5 Stainless Steel / Blue / Calf

The Oris Aquis 01 752 7733 4135-07 5 24 10EB features a 24mm lug width, measured between the internal terminals of the case. This width is specific to this model and ensures a perfect fit without play or excessive tension. Any aftermarket strap must respect this dimension to fit correctly.

For an Oris Aquis, several materials are recommended depending on use: alligator with vegetable tanning for daily elegance, calf leather with grain texture for versatility, ballistic nylon NATO for practicality and resilience, or FKM rubber for actual diving practice. Each choice offers different compromises between aesthetics, durability and diving functionality.

The strap is changed by removing the spring bars connecting the strap to the case lugs. Use a dedicated spring bar tool to gently compress the internal spring and slide the pin out of the housing. Once the lugs are free, insert the new strap and reinsert the spring bar until the spring clicks into place. The operation requires care to avoid scratching the case.

Yes, any strap with a 24mm lug width is compatible with your Oris Aquis. High-quality artisanal aftermarket straps allow you to completely personalise the watch, switching from a diving style to an elegant or sporty one. Compatibility is guaranteed by the correct lug width; there are no particular constructive restrictions.

A quality leather strap (alligator, calf, shell cordovan) with regular maintenance lasts an average of 5-8 years. Durability depends on exposure to humidity, salt sweat and UV rays. To extend useful life, we recommend drying the strap after prolonged contact with salt water and periodically applying a specific conditioner for vegetable-tanned leathers. A rubber strap has superior longevity (10-15 years) but requires fewer maintenance interventions.
