Strap for Aquaracer 300M Quartz 27 Stainless Steel / Yellow Gold / MOP -Diamond / Bracelet

The lug width is 20mm. This measurement represents the distance between the two metal spring bars (pins) that attach the strap to the case lugs. For the WAF1451.BB0814, this width is standardised and ensures universal compatibility with any strap manufactured to Swiss specifications.

For the WAF1451.BB0814, we recommend alligator, vegetable-tanned calf leather, or shell cordovan for formal occasions; for frequent marine use, shell cordovan offers superior water resistance. Sporty alternatives include vulcanised rubber or NATO fabric, ideal for regular diving due to rapid drying properties.

Strap replacement requires a spring bar tool: locate the spring bars (small metal cylinders connecting the strap to the case lugs), use the tool to compress the bar inward, and carefully pull outward. Repeat on the opposite side, align the new strap holes with the lugs, and reinsert the spring bars until they click into place.

Yes, all straps manufactured for 20mm lug width are compatible. Milano Straps offers a curated selection of handcrafted straps in alligator, calf leather, shell cordovan, and rubber, customisable in size, initials, and stitching thread colour.

A quality alligator or calf strap typically lasts 3–5 years with moderate use, thanks to the natural water-resistant properties of the leather. Shell cordovan, being more structured, exceeds 5 years even with salt-water exposure. Longevity depends on ambient humidity and post-immersion drying frequency; Casati Milano guarantees 18 months on every bespoke creation.
