Strap for Oris Aquis 01 400 7763 4135

The Oris Aquis 01 400 7763 4135 features a lug width (anse) of 24 millimetres. This measurement represents the distance between the centres of the two lugs that connect the strap to the case. To verify it correctly, use a digital calliper, measuring centre-to-centre of the lugs and excluding the curved terminals. The 24 millimetres specification is unique to this reference and incompatible with straps designed for the more common 20 or 22 millimetre widths.

The ideal strap depends on intended use and aesthetic preference. For daily wear and light diving, a vegetable-tanned leather strap imparts character and develops natural patina over time, creating a fascinating contrast with the brushed steel case. A satinised rubber strap is the optimal choice for actual diving, offering ease of maintenance and salt-water resistance. NATO nylon at high tensile strength provides aesthetic versatility and easy changeover capability. We advise against delicate materials such as alligator, which would create stylistic dissonance with the robust tool-watch nature of this dive instrument.

The Oris Aquis 01 400 7763 4135 employs standard spring bars with bayonet-style curved terminals. To change the strap: 1) gather a spring bar removal tool or thin flat screwdriver; 2) position the watch on a clean cloth with the strap facing upward; 3) gently push the pin inward toward the case to release it from the lug; 4) extract the old strap and insert the new one, aligning the holes carefully. The operation demands patience and precision to avoid scratching the case. Alternatively, engage professionals such as Casati Milano for secure changeover.

Yes, any universal strap of 24 millimetres width is compatible with the Oris Aquis 01 400 7763 4135, provided the terminals are standard (curved bayonet or straight) and the lug width is measured with precision. MilanoStraps offerings in the 24mm collection are tested on this model and guarantee perfect compatibility. Always verify that the lug width corresponds exactly before purchase to avoid misfit.

A quality artisanal vegetable-tanned leather strap, such as our Toscano Suprema, has an average lifespan of 3–4 years under daily use and occasional immersion. Longevity depends on factors including: frequency of salt-water exposure, ambient humidity, periodic maintenance (rapid drying after water contact) and storage in non-excessively dry environments. Leather tanned with vegetable tannins, thanks to its natural porosity, ages well and develops characteristic patina over time. To extend strap life, alternate with a rubber strap during frequent diving, reserving leather for more controlled and formal wear.
