Strap for Rectangular Date 30 Stainless Steel / Silver - Roman

The lug width of the Rectangular is precisely 21 millimetres. This technical specification corresponds to the distance between the two lugs (spring bar attachments) on the case. To measure correctly, use a digital calliper or ruler, positioning the tip between the lugs. This tolerance is strict: a strap outside this specification will not be compatible with the case.

The choice depends on intended use. For formal contexts, we recommend cognac brown alligator or vegetable-tanned black calf leather: both emphasise the rectangular case geometry and develop a fascinating patina over time. For daily wear, a grey or navy NATO canvas offers practicality without sacrificing elegance. Satin-finish FKM rubber is ideal for humid environments. Each choice must respect the model's constructive minimalism.

Strap replacement occurs via the lateral spring bars of the case. Use a dedicated spring bar tool to compress the spring mechanisms and slide out the old strap. Position the new spring bars into the holes of the new strap and, using the same tool, ensure the springs lock securely. Verify the attachment by pulling the strap: it should not move. The procedure requires patience but no specialist expertise.

Yes, absolutely. The Rectangular accepts aftermarket straps from any brand as long as the lug width is precisely 21 millimetres. We recommend bespoke artisanal leather straps (alligator, shell cordovan, vegetable-tanned calf) or woven NATO: they guarantee full compatibility and often superior aesthetic personalisation compared to factory solutions. Always verify the 21mm specification before purchase.

Durability depends on intensity of use, climate and leather quality. Premium calf or alligator develops a splendid aged patina and lasts 3–5 years under moderate daily use. In humid climates or with intensive use, lifespan reduces to 2–3 years. Vegetable-tanned straps tend to last longer as they improve with time. Canvas NATO resists 5–7 years. FKM rubber has similar longevity to leather but develops less aesthetic evolution. We recommend periodic inspection of the spring bars.
