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

The lug width is 18mm—a specific and rare dimension that characterises this model. This measurement requires straps built specifically for the Aquis, incompatible with standard 16mm or 20mm widths. Measurement is performed using a digital calliper between the spring bar seats, and is an essential preliminary operation before ordering an aftermarket strap.

The Aquis 36mm pairs ideally with straps in vegetable-tanned alligator, shell cordovan, or calf leather. Alligator provides grip and develops patina over time; cordovan guarantees maximum durability; calf leather allows refined subtlety. Synthetic straps are inadvisable, as they would visually overburden the case. NATO and technical rubber remain sporting alternatives for intensive underwater use.

Strap replacement requires removal of the spring bars using a dedicated tool (spring bar tool). Position the watch on a soft cloth, insert the tool tip into the lateral slots of the spring, lift gently until the bar extracts. Perform the operation on both sides, then slide the new strap through the case lugs and reinsert the bars. This operation is recommended at Casati Milano to preserve case integrity.

Yes, with the essential condition that they are constructed specifically for 18mm lug width. Market standards (16mm, 20mm) will not fit. MilanoStraps offers personalised artisanal straps for this measurement, in premium leather. Always verify before purchase that the lug width corresponds exactly to 18mm.

A quality leather strap (vegetable-tanned alligator or calf) resists 3-5 years under ordinary use conditions. Salt marine exposure accelerates wear; it is advisable to replace the strap before prolonged immersions. The patina that develops is an intended characteristic, not degradation: small surface cracks are normal. Rubber or NATO straps offer superior chemical-environmental resistance for intensive underwater use.
