Frequently asked questions

What is the lug width of the Oris Aquis 01 749 7734 7154-Set?

The Oris Aquis 01 749 7734 7154-Set features a 22mm lug width (ansa in Italian terminology). This measurement is specific to this generation of Aquis and results from the optimal proportioning of the 43.50mm case. To verify the lug width of your watch, remove the current strap by extracting the spring bars from the lugs on either side of the case, then measure the distance between the inner edges of the two holes using a digital calliper.

What is the best strap for the Oris Aquis 01 749 7734 7154-Set?

There is no absolute 'best', but rather options suited to different use cases. For underwater diving, we recommend a NATO strap in durable nylon or a Tropic rubber strap with a deployante clasp. For daily sportive elegance, an alligator leather from vegetable tanning in dark tones (black, burgundy brown) harmonises beautifully with the titanium case and ceramic bezel. For intense trekking, silicone rubber offers complete water resistance and minimal maintenance. Your choice should reflect your lifestyle and how you wish to express the technical identity of the Aquis.

How do I change the strap on my Oris Aquis 01 749 7734 7154-Set?

The strap is changed by extracting the spring bars from the two holes on the case, one on each side. Use a dedicated spring bar tool or a small flat-head screwdriver to gently lever the bar out. Once removed, align the new strap's lugs with the case holes and press the spring bar inward until it clicks. Verify that the bar is fully seated, creating a small gap between the lug and case (approximately 1-2mm). This operation takes only minutes and requires no specialist technical knowledge.

Is the Oris Aquis 01 749 7734 7154-Set compatible with quality aftermarket straps?

Yes, absolutely. The 22mm lug width is an established standard in wristwatch manufacturing, and numerous quality artisans produce compatible straps in leather, fabric, and rubber. Milano Straps offers a comprehensive collection of 22mm straps in alligator, vegetable-tanned calf, NATO, and rubber, crafted to the same quality standards as European specialist manufacturers. Adoption of aftermarket straps does not invalidate your Oris warranty, provided you do not damage the case during installation.

How long does a leather strap last on the Oris Aquis 01 749 7734 7154-Set?

Longevity varies significantly depending on material, finish, and usage. A vegetable-tanned calf strap, worn regularly (4-5 days per week) in dry conditions, typically lasts 2-3 years before requiring replacement, developing a beautiful natural patina in the process. A high-quality alligator strap may last 3-5 years. If frequently exposed to moisture, perspiration, or water immersion, lifespan reduces to 1-2 years. Rubber and NATO straps are essentially unlimited in durability (exceeding 10 years), but suffer from passant fractures or elasticity deterioration after intensive use. Regular maintenance (cleaning, drying) significantly extends the life of any strap.
