Strap for Aquis Date 36 DLC / Black / Rubber

The lug width of the Oris Aquis 01 733 7652 4725-07 4 18 34B is 18 millimetres. This is the classic standard for 36mm sport watches and is critical for strap compatibility. The measurement is taken with a digital calliper positioned between the two lugs: it must read 18.0 ± 0.2mm to ensure correct strap seating without binding.

The optimal strap choice depends on intended use. For daily elegance, we recommend alligator leather with vegetable tanning in medium grain, mid-brown or tobacco tones, which complements the sunburst dial whilst maintaining aesthetic coherence. For humid environments or recreational swimming, a high-density nylon NATO or FKM rubber strap offers complete water impermeability. Vegetable-tanned calf leather represents the most versatile compromise between formality and practicality.

Use a high-quality watch spring bar tool in stainless steel, not plastic. Place the watch on a soft pad to protect the case. Insert the tool into the curved section of the lug towards the old strap, applying gentle pressure until the spring retainer releases. Repeat on the other side. Verify that the new strap is compatible with the 18mm lug width before final installation.

Yes. All straps with 18mm lug width are compatible with your Aquis. Milano Straps offers a specialised collection of 18mm straps in vegetable-tanned leather, NATO, and high-performance rubber, selected for aesthetic harmony with the 36mm case proportions and certified quality manufacturing standards.

A vegetable-tanned leather strap, with proper maintenance, has functional durability of 3–4 years under moderate daily use. The permeability of vegetable leather enables natural transpiration, reducing bacterial proliferation and odour. The patina that develops over time is a desirable characteristic, not degradation. Prolonged exposure to salt water (marine use) accelerates wear; we recommend a rubber strap for intensive maritime use.
