Strap for Rectangular Date 25.9 Stainless Steel / Black

The lug width is 16mm. This measurement is critical for identifying compatible straps. Lug width is measured in millimetres between the two points where the strap attaches to the case, using a calliper positioned perpendicularly to the watch's axis.

To preserve the Art Déco aesthetic, we recommend crocodile or alligator leather with fine grain in dark or cognac shades, or vegetable-tanned calf that develops patina over time. For daily versatility, a heavyweight cotton NATO or technical rubber of quality construction offers practicality. Choice depends on use case and personal preference for rigidity versus flexibility.

Strap replacement requires a spring bar remover tool. Position the watch on a stable surface, locate the small lateral hole beneath each lug, insert the tool gently to compress the internal spring, and slide out the used strap. Insert the new strap, confirming that both springs engage correctly. Avoid forcing to prevent damage to the lugs.

Yes, provided they meet the 16mm standard measurement and their end links suit the case dimensions. Milano Straps offers a curated selection of 16mm straps specifically tested for compact watch proportions such as the Rectangular. We recommend verifying end link dimensions before purchase.

Durability depends on material quality and usage patterns. A well-crafted alligator or vegetable-tanned calf strap, worn regularly, maintains structural integrity for 3–5 years before replacement becomes necessary. Patina development and micro-creasing are natural and desirable. Exposure to perspiration, water, and UV radiation accelerates ageing. With proper care (periodic cleaning, drying) and seasonal rotation with alternate straps, longevity increases substantially.
