Frequently asked questions

What lug width does the Oris Aquis 01 733 7730 4153-07 4 24 63EB have?

The Oris Aquis 01 733 7730 4153-07 4 24 63EB features a lug width (ansa) of 20mm, a historic standard in professional dive watch engineering. This measurement is taken between the inner lugs of the case and allows for robust strap integration without aesthetic compromise.

What is the best strap material for the Aquis model 01 733 7730 4153-07 4 24 63EB?

Material choice depends on intended use: alligator with vegetable tanning offers elegance and natural patina development; calf leather provides comfort and marine humidity resistance; nylon NATO ensures maximum practicality and rapid drying; vulcanized rubber represents the most technically resilient option for frequent diving.

How do I change the strap on the Oris Aquis 01 733 7730 4153-07 4 24 63EB?

Strap replacement is accomplished via removal of the spring bars (lugs pins) connecting the strap to the case. Using a dedicated tool (spring bar tool), extract the pin gently, insert the new 20mm strap, and reinsert the pin ensuring secure engagement. The procedure requires approximately 2-3 minutes per side.

Which aftermarket straps are compatible with the Oris Aquis 01 733 7730 4153-07 4 24 63EB?

All straps featuring a 20mm lug width are fully compatible. MilanoStraps offers dedicated collections in alligator, calf, shell cordovan, rubber and NATO, customizable for wrist length and buckle finish. Compatibility is guaranteed by Oris standardisation of lug width across the entire Aquis range.

What is the lifespan of a leather strap for the Oris Aquis?

A high-quality leather strap (alligator or vegetable-tanned calf) typically lasts 3-5 years with daily use and proper maintenance. Frequent exposure to seawater reduces lifespan to 2-3 years if untreated. Vulcanized rubber and nylon NATO carry indefinite durability with zero material deterioration.
