Strap for Tangente 38 A Century of Bauhaus Red

The Tangente 165.S4 features a lug width of 18 millimetres. This measurement is determined by the 37.50 mm case diameter and the Bauhaus-inspired design geometry. It is essential to verify lug width with precision before purchasing an aftermarket strap, as even 0.5 mm variance results in structural misalignment.

For the Tangente 165.S4, straps in alligator, shell cordovan, or vegetable-tanned calf are recommended. Alligator maintains aesthetic austerity through its structured grain; cordovan develops natural patina reflecting the case's ageing process. Calf in châtaigne or havana tones remains appropriate for informal contexts. Rubber straps are inadvisable unless specific technical requirements apply.

Strap replacement on the Tangente is accomplished by extracting the spring bars using a specialised tool. We recommend entrusting this procedure to a qualified watchmaker or Atelier Casati Milano to prevent damage to case or strap. The process requires approximately 10 minutes and ensures perfect lug alignment on the case.

Yes, compatible aftermarket straps may be used provided they respect the 18 millimetre lug width specification. Milanostraps.it offers a curated collection of 18mm artisanal straps in leather, NATO, and rubber, selected for aesthetic proportionality and construction quality. We recommend selecting materials that maintain coherence with the watch's minimalist design language.

Leather strap longevity depends on usage intensity, climatic conditions, and material composition. An alligator or vegetable-tanned cordovan strap, subject to daily wear, maintains structural integrity for 4–6 years before requiring replacement. The natural patina that develops does not indicate degradation: it represents controlled ageing. Atelier Casati Milano recommends seasonal rotation to extend strap service life.
