Frequently asked questions

What is the exact lug width of the Oris Aquis 01 733 7653 4127-07 8 26 01PEB?

The lug width is 26mm. This is measured from the inner tip of one lug to the other in a straight line. This standard allows the use of straps with adequate thickness (4-5mm) without compromises on fit. Always verify by measuring your watch directly before ordering a strap.

Which strap is best suited for an Oris Aquis 01 733 7653 4127-07 8 26 01PEB?

It depends on intended use. For maximum aesthetic coherence, we recommend a black or midnight blue alligator: it maintains technical authority without betraying the sporty character. If you prefer absolute robustness, an FKM rubber strap offers indestructibility. For everyday versatility, a vegetable-tanned calf with marked texture is the best compromise between elegance and durability.

How do I change the strap on my Oris Aquis?

The Aquis is equipped with straps via standard spring bars. Obtain a spring bar removal tool or visit a watchmaker. Insert the bifid tip under the end of the spring bar, press slightly inward to compress the spring, then extract the bar. Position the new strap and reinsert the bar until it clicks into place. Avoid forcing to prevent damage to the lugs.

Can I use an aftermarket 26mm strap on this watch?

Yes, provided it is certified for 26mm lug width. Milano Straps supplies exclusively handcrafted straps compatible with this measurement, available in vegetable tanning, technical rubber and NATO. Always verify that the strap is not too thick (max 5mm) to avoid play between lug and passant.

How long does a leather strap last on a dive watch like the Aquis?

An alligator in vegetable tanning lasts 3-5 years with moderate daily use. The Aquis, being a diver with high water resistance (300m), can be exposed to salt water, which accelerates leather ageing. We recommend drying the strap after every prolonged contact with sea water and periodically applying a protective wax. Rubber straps last longer (7-10 years) but still deteriorate under intense UV exposure.
