Strap for Aquis Date 36.5 Stainless Steel / MOP / Rubber

The lug width of this model is precisely 19mm, measured between the two internal lugs of the case, from lug to lug, excluding the thickness of the lug pins themselves. This dimension is specific to compact Swiss diving watches and ensures harmonious proportions with the 36.50mm case diameter.

The mother-of-pearl dial of your Aquis pairs ideally with straps in dark brown alligator with aged patina, which enhances the lustre without competing visually. Alternatively, black calf leather with vegetable tanning or a natural beige linen NATO maintains the subtle elegance of the 36.50mm case. Avoid thicknesses exceeding 4mm to prevent overscaling the overall composition.

The procedure requires a spring bar tool with nylon or plastic tips. Insert the tip into the space between the lug and the lug pin, apply light pressure to release the pin, then pull out the old strap and insert the new one, aligning the lug holes. The operation takes a few minutes and requires no case disassembly. We recommend performing this on a flat, well-lit surface.

Yes, the reference 01 733 7792 4151-07 4 19 61FC is fully compatible with certified aftermarket straps in 19mm width. The standardised lug width allows the use of materials and brands other than Oris: leather, NATO, rubber. What matters is choosing proportionate thicknesses (1.8–4mm) and finishes that do not damage the case lugs.

Durability depends on frequency of wear, exposure to humidity, and tanning quality. A vegetable-tanned leather strap, worn daily in dry environments, maintains structural integrity for 3–5 years before showing critical wear. Patina ageing begins after 6–12 months and represents an aesthetic process, not degradation. In humid environments or during bathing, durability is reduced to 18–30 months. Rubber remains unaltered for 5–7 years of continuous use.
