Strap for Tangente 38 Datum Haifischgrau

The lug width of the Nomos Glashütte Tangente 179.S20 is exactly 18 millimetres. This dimension has been calculated in proportion to the 37.50mm case diameter to maintain the aesthetic and ergonomic balance characteristic of Bauhaus design. It is essential to verify that the strap has an 18mm lug width to ensure correct fit on the case lugs and prevent loosening or instability.

For the Tangente 179.S20, we recommend straps in vegetable-tanned leather, particularly in neutral colours such as tan, black, or burgundy. Shell cordovan, with its smooth and uniform surface, amplifies the minimalist geometry of the case. Alternatively, a calf leather strap or a nylon satin NATO maintains the simplicity of the design whilst offering versatility of use. The choice depends on your intended usage context and personal aesthetic intention.

The strap is changed via the two spring bars (also called lugs or pomels) that connect the strap to the case lugs. Using a dedicated tool, apply gentle downward pressure to one of the spring bars to release the end of the current strap. Repeat for the other bar. Subsequently, lodge the new strap into the same spring bars until the locking click is heard. It is recommended to work on a soft surface to avoid scratching the case.

Yes, any strap with an 18mm lug width is compatible with the Tangente 179.S20. At milanostraps.it, a dedicated collection of 18mm straps is available in various materials: vegetable-tanned leather, shell cordovan, alligator, calf leather, rubber, and NATO. All straps are handcrafted and verified for correct dimensional tolerances.

The lifespan of a leather strap depends on intensity of use, the specific material, and maintenance. Quality leather, subjected to moderate daily use, maintains structural integrity for 3-5 years. Shell cordovan, thanks to the natural density of the material, tends to last longer. Patina and micro-alterations are natural phenomena; true structural failures manifest as tears or detachment of the spring bars. Regular cleaning with a damp cloth and occasional application of leather-specific creams significantly prolong the life of the strap.
