Strap for Rectangular Date Diamonds 25.9 Stainless Steel / Black / Bracelet

The lug width of the Oris Rectangular 01 561 7621 4964-07 8 16 75 is 16mm. This measurement represents the distance between the two attachment points on the case where the strap connects. To verify it correctly, position a ruler between the centre of the top lug and the centre of the bottom lug. This is a specific dimension requiring bespoke straps, not universal alternatives.

For the stainless steel Rectangular with its Art Déco proportions, we recommend satin-finished black or chocolate-brown alligator with vegetable tanning. The Mississippi alligator in black from Milano Straps' Dress Heritage collection is the most authentic choice: the reptile's natural texture dialogues perfectly with the geometric aesthetics of the 1930s. Shell cordovan is a noble alternative for those preferring visually intense patina. Canvas NATO straps function in sporty contexts without compromising elegance.

Strap removal requires spring bar removal tools. Position the tool in the lateral notch of the lug, push gently to release it, and extract the metal pin. Insert the new strap into the attachment slots and press until locked. If uncertain, consult an authorised Oris service centre or your trusted watchmaker. Milano Straps straps arrive with pre-mounted lugs: you simply exchange the deployante clasp pin between old and new strap.

Yes, absolutely. The lug width is standardised at 16mm. Milano Straps manufactures bespoke leather straps precisely for this width. What matters is verifying consistent strap thickness (3.5–4mm for the Rectangular) and deployante clasp quality to ensure secure closure. Avoid cheap universal straps: an artisan specialising in 16mm understands the correct proportions.

Durability depends on material and usage frequency. Natural alligator lasts approximately 5–7 years of regular wear; shell cordovan even 10+ years owing to its dense fibrous structure. Vegetable-tanned calf averages 4–6 years before visible wear (which becomes beautiful patina). Critical factors: frequency of wear, sun and humidity exposure, maintenance consistency. Keep the strap dry and nourish the leather with specific balms every 6–12 months to maximise longevity.
