Strap for Rectangular Day Date 30 Stainless Steel / Silver / Bracelet

The lug width is 20mm. Measure with a digital calliper between the two spring bar lugs of the case. This specific measurement requires dedicated straps, not common production standards.

We recommend alligator with vegetable tanning for constructivist sobriety, fine-grained calf for daily elegance, cotton NATO for summer functionality, and isothermic rubber for humid environments. Mixed fabrics are discouraged.

Use a spring bar tool. Position the case on a soft surface, push downward on the small spring under each lug alternating sides, remove the bar, insert the new strap, reinsert the bar ensuring symmetrical positioning.

Yes, any 20mm strap is mechanically compatible. However, we recommend artisanal products respecting the formal language of the Rectangular. Avoid straps with heavy buckles or excessive ornamentation that would betray constructivist geometry.

A quality vegetable-tanned alligator lasts 3–5 years with regular maintenance (monthly cleaning, quarterly conditioning). Calf leather lasts 2–3 years. Durability depends on sun exposure, humidity, and frequency of use.
