Frequently asked questions
What is the exact lug width of the Oris Aquis 01 733 7731 4191-07 8 18 05P?
The lug width is 18mm. This measurement reflects the proportional relationship between the 36.50mm case diameter and the dial width. Verify compatibility by measuring the distance between the strap attachment pins: 18mm is the international standard that guarantees full interchangeability with aftermarket straps of the same width.
What is the best strap for the Oris Aquis 36.50mm?
The choice depends on intended use. An alligator strap with vegetable tanning offers formal elegance whilst maintaining technical character; a perforated calf provides daily practicality with drainage; a NATO Cordura strap ensures robustness and modularity; FKM rubber represents the ideal solution for professional aquatic environments. Each material responds to different aesthetic and functional requirements.
How do I change the strap on this model?
The Aquis 01 733 7731 4191-07 8 18 05P features an integrated lug with standard attachment pins. The procedure requires a simple spring bar tool to release the lower and upper lugs. No intervention on the watch itself is necessary. Straps in 18mm width insert quickly into the same anchor holes.
Are aftermarket 18mm straps compatible with this Oris?
Yes, fully compatible. The 18mm lug width is the recognised international standard. Any quality strap constructed with standard 18mm pins fits the Aquis 01 733 7731 4191-07 8 18 05P without modification. Milano Straps offers a complete selection of straps in this size, from artisanal leather to technical fabrics.
How long does a leather strap last on a diver watch like the Aquis?
A quality leather strap (alligator or calf) withstands 3-5 years of daily use, considering exposure to humidity, chlorine and UV rays. Durability increases if the strap is not subjected to prolonged immersion and if periodically maintained (gentle cleaning, conditioning). For intensive aquatic use, FKM rubber is recommended, guaranteeing 5-7 years of reliability without deterioration.
