Strap for Tangente 2date / Closed Case Back

The Nomos Glashütte Tangente 135.SB features a lug width of 19mm, a specific intermediate dimension for this particular model. This measurement is taken internally between the two lugs at the attachment point of the case. It is essential to verify this measurement before ordering a strap, as 18mm, 20mm, or 22mm straps will not be compatible with the lugs of the 135.SB.

The choice depends on intended use and personal style. For formal elegance, we recommend a superior quality alligator strap with vegetable tanning in cognac or teak brown. For daily versatility, black opaque calf leather represents the ideal compromise between durability and aesthetics. For discrete sporting contexts, a navy NATO strap with grey stripe maintains Bauhaus coherence. Black FKM rubber offers the most contemporary and minimalist choice.

The 135.SB uses a standard lug system with a removable pin. To change the strap: position the watch on a soft pad, locate the pins running through the side lugs, use a spring bar tool to remove the pin by applying light downward pressure, remove the previous strap, align the new strap with the lugs and reinsert the pin until the locking click is felt. The procedure takes approximately two minutes with the correct tool.

Yes, any strap designed for a 19mm lug width is compatible with the 135.SB, regardless of manufacturer. Compatibility is determined solely by lug width, not by brand. MilanoStraps offers a selection of alligator, calf, NATO, and rubber straps in 19mm specifically designed for watches with this lug dimension, guaranteeing artisanal quality and finishes coherent with the spirit of the 135.SB.

Lifespan depends on material and usage. An alligator strap with vegetable tanning typically lasts 5-7 years under moderate daily wear, developing a patina that ennobles appearance over time. A calf leather strap has similar durability with regular maintenance. FKM rubber straps have a useful life of 8-10 years before showing signs of ageing. Longevity increases if the watch is not worn daily and if the strap receives periodic maintenance—gentle cleaning, thorough drying, and conditioning.
