Strap for TT1 Day Date Stainless Steel - Rubber / Black / Rubber

The Oris TT1 01 635 7518 4464-07 4 24 14 features a 24mm lug width, measured precisely between the spring bar attachment points on the case. This dimension is standard across this model and ensures any compatible aftermarket strap fits without adapters or modifications.

We recommend three primary options: vegetable-tanned leather in taupe or cognac brown for daily elegance with natural patina development; alligator in slate or dark brown for uncompromising formality; and 440-denier Italian-woven NATO for authentic sportiness during intensive wear. Selection depends on intended use context and aesthetic preference.

Strap replacement requires: a quality spring bar tool, precise and controlled movements to avoid case scratching. Place the watch on a soft surface, insert the thin tool into the lateral spring bar spaces, press gently towards the centre, and extract with steady motion. Reverse the process with the new strap, ensuring both sides engage with secure clicks.

Fully compatible. All Milano Straps in our 24mm collection have been tested on TT1 models, guaranteeing total compatibility. We offer leather, alligatore, NATO and FKM rubber options in this size, with customisation (passant colour, deployante type, finishing details). Each piece is handcrafted at Atelier Casati Milano.

A vegetable-tanned leather strap on a TT1 typically lasts 3–7 years of regular daily wear, dependent on climate, rotation frequency, and maintenance. Humid environments accelerate wear; rotating between multiple straps extends individual lifespan. The leather develops natural patina over time, making degradation a visually interesting process. Alligatore offers superior longevity (8–12 years) due to hide density.
