Strap for Aquis Date 40 Stainless Steel / White / Bracelet

The lug width is 21mm. This dimension can be verified using a digital calliper positioned between the two case lugs. It is essential to check this measurement before purchasing an aftermarket strap to avoid lateral play or excessive tension during installation.

We recommend a vegetable-tanned alligator in dark brown for formal wear, or structured vulcanised rubber for aquatic environments and intensive use. A cotton NATO strap in 18oz weight represents the ideal compromise between technical practicality and discreet elegance, maintaining visual coherence with the watch's diving-focused design.

The strap is replaced using a spring bar tool: insert the tool tip into the lateral access hole of the lug, gently depress the internal spring, and extract the metal pin (spring bar). Repeat the same procedure on the opposite side. To install the new strap, position the terminals in the case seats and compress the pin until it locks in place with an audible click.

Yes, provided it is dimensioned specifically for a 21mm lug width. Artisanal straps constructed to professional standards maintain precise tolerances (21.00mm ±0.2mm) and guarantee compatibility without compromise. Always verify that the strap features stainless steel terminals of quality equivalent to the case.

A quality vegetable-tanned alligator or calf leather strap has an average lifespan of 4–6 years in non-aquatic daily wear. Frequent exposure to seawater or chlorine reduces this duration to 2–3 years. To maximise longevity, thoroughly dry the strap after water contact and condition the leather every 6–8 months with quality leather-specific products.
