Strap for Purist Typ 1 Datum Stainless Steel / Black

The P1DS-LS features a lug width of 20 millimetres. This dimension is specific to the model and reflects the refined proportions of the 40mm case. Always verify visually that the replacement strap fits precisely between the lugs without lateral play.

For the minimalist character of the P1DS-LS, we recommend alligator in cognac brown with fine grain texture, or vegetable-tanned calf leather that develops natural patina over time. Alternatively, a polyamide NATO in smoke grey or aged cordovan calf create noble pairings whilst maintaining the German design's inherent simplicity.

The strap is removed by gently unscrewing the integrated lugs from the case (typically 1.5mm screws or smaller, depending on the model). Once the lugs are liberated, slide off the worn strap and insert the new one, maintaining its natural angle. Retighten the lugs gently until secured, without forcing. Alternatively, entrust the task to a specialised watchmaker.

All straps with a 20mm lug width are compatible with the P1DS-LS. Milanostraps.it offers a comprehensive range of artisanal options: alligator, calf, shell cordovan, NATO and FKM rubber. Each strap features quality stainless steel lugs and is available with a deployante or simple buckle.

Durability depends on usage and material. Superior-quality alligator with vegetable tanning resists 3–5 years if worn daily. Aged cordovan calf can last 4–7 years, developing noble patina over time. Periodic strap replacement does not compromise the watch's value; indeed, personalisation capability aligns with the P1DS-LS's constructivist philosophy.
