Strap for Aquis Date Diamonds 36 Stainless Steel / Brown - Diamond / Rubber

The lug width of the reference 01 733 7652 4192-07 5 18 12FC is 18mm. This dimension is measured internally between the two metal shoulders protruding from the case, parallel to the dial. It is an intermediate width that defines compatibility with aftermarket straps and conditions the visual perception of case-to-wrist proportion.

For this model, straps that engage with the dual material nature of steel and ceramic are recommended. An alligator with vegetable tanning creates elegant contrast through its irregular grain; supple cognac calf amplifies tactile continuity; a navy NATO adds gravitas without visual competition; a vulcanised rubber strap maintains sports atmosphere. Choice depends on intended use and desired chromatic dialogue with the satinised ceramic bezel.

Strap change requires a dedicated tool (spring bar tool) to remove the elastic pins securing the strap to the case lugs. Position the tool in the lower seat of the pin, lift gently to compress the internal spring, extract the pin. Verify that the new strap has the correct lug width (18mm) before inserting pins. Avoid excessive case twisting during the operation.

Yes, provided the lug width is exactly 18mm. Compatibility depends on the standard dimension, not on the watch brand. However, high-quality artisanal straps—such as those in vegetable-tanned alligator—amplify aesthetic coherence and durability. Milano Straps offers 18mm straps specifically calibrated for compact Swiss sports watches.

A vegetable-tanned leather strap lasts on average 4-6 years in moderate daily wear (no repeated immersions). Durability depends on exposure to moisture, perspiration, thermal variations and leather quality. Natural alligator is more resistant than calf thanks to fibrous grain structure. The patina that develops over time is normal evolution, not degradation: it represents the material memory of the strap.
