Strap for Tangente 2date Blue / Closed Case Back

The lug width (also referred to as strap width) of the Nomos Glashütte Tangente 136.SB is exactly 19.00 millimetres. This specific measurement requires straps manufactured expressly for this dimension. It is important to measure the distance between the two lugs of the case to confirm compatibility before ordering an aftermarket strap.

The optimal strap choice depends on intended use and aesthetic preferences. For formal elegance, shell cordovan or vegetable-tanned calf leather represent supreme options, as they develop a unique patina over time. For everyday versatility, a NATO in technical textile or a vulcanised rubber strap offer practicality and weather resistance whilst maintaining the Bauhaus rigour of the Tangente. Alligator leather represents the ultimate luxury choice, with natural grain that harmonises perfectly with the minimalist proportions of the case.

The strap is removed using a spring bar tool, a specialised implement that allows you to compress the metallic springs (spring bars) located at the extremities of the strap itself. Position the tool in the lateral slots of the lug, apply gentle pressure to release tension, and the strap will detach from the case. The operation requires care to avoid scratching the case. If uncertain, strap replacement can be performed by a qualified watchmaker.

Yes, any strap of precisely 19.00 millimetres width is compatible with the Nomos Tangente 136.SB. However, it is essential to purchase straps from specialised suppliers that guarantee precise manufacturing tolerances. A lower-quality strap may feature overly loose tolerances, causing play in the spring bars and premature lug wear. We recommend selecting straps manufactured in vegetable-tanned leather, technical NATO, or vulcanised rubber, verified for this specific measurement.

The lifespan of a leather strap depends on the quality of tanning, climatic conditions, and intensity of use. A high-quality strap in vegetable-tanned leather may last 3-5 years of daily wear before requiring replacement. Shell cordovan straps, owing to the density of the material and natural resilience, can exceed 5 years of service. Leather inevitably exhibits signs of wear and cracking over time; this process contributes to the characteristic patina and charm of the watch. A vulcanised rubber strap offers superior durability in humid environments, though it still requires periodic inspection for degradation.
