Strap for Oris Aquis 01 733 7652 4135

The lug width of the Oris Aquis 01 733 7652 4135 is 18 millimetres. This measurement refers to the distance between the axes of the two fixing holes that anchor the strap to the case. To verify this measurement, simply remove the original spring bar and measure with a digital calliper or ruler the distance between the two holes: you will obtain exactly 18mm.

The Oris Aquis 01 733 7652 4135 adapts excellently to various materials depending on intended use. A premium leather with vegetable tanning, such as alligator or calf, amplifies formal sophistication whilst maintaining functionality. For intensive diving use or marine conditions, vulcanised FKM rubber ensures resistance to saltwater and constant moisture. A nylon NATO, conversely, represents the versatile compromise between durability and casual appeal.

Changing the strap on the Oris Aquis requires the use of a spring bar tool or a thin, non-sharp metal blade. Locate the connecting bars on the inner side of the lug: gently insert the tool into the hole closest to the bar to compress the internal spring, then extract the bar itself. Repeat the operation on the opposite lug. To install the new 18mm strap, reinsert the bars into the new strap's holes, ensuring they are firmly anchored before wearing the watch.

All straps with an 18-millimetre lug width are compatible with this model. You may choose from artisanal leathers (alligator, calf, crocodile), technical straps (NATO, Zulu), rubber and specialised resin straps. Always verify that the strap has fixing holes precisely 18mm apart to ensure correct anchoring and harmonious fit on the case.

The lifespan of a leather strap depends on the quality of tanning, the thickness of the material, and the frequency of use. A good-quality calf offers approximately 3–4 years of regular daily use, developing a natural patina that enhances aesthetic character. An alligator with vegetable tanning can exceed 5–6 years owing to greater fibre density and wear resistance. Exposure to direct sunlight, constant humidity, and mechanical stress accelerate ageing; proper maintenance (periodic cleaning, conditioning with natural oils) significantly extends its useful life.
