The Heritage

The Nomos Glashütte Tangente 135 is a 37.50 mm stainless steel watch embodying Bauhaus rationalism in watchmaking. It features a white dial with geometric indices, manual DUW 4601 movement visible through the caseback, power reserve indicator, date display, and small seconds. The 19 mm lugs follow classical Bauhaus proportions, with the case finishing combining satin vertical surfaces and polished horizontals. The DUW 4601 is one of few manual movements entirely developed in a German manufacture.

FAQ

What is the lug width of the Nomos Glashütte Tangente 135?

The Nomos Glashütte Tangente 135 features 19 mm lug width. Measured internally between the two lugs, this dimension is uncommon in contemporary watchmaking and requires straps specifically manufactured for this specification.

Which strap pairs best with the Tangente 135?

Shell cordovan in burgundy or mahogany delivers maximum aesthetic potential: it develops an extraordinary patina and creates elegant contrast against the white dial. Alternatively, vegetable-tanned calf leather in natural brown maintains Bauhaus harmony, or charcoal NATO cloth for a contemporary constructivist aesthetic.

How do I change the strap on the Nomos Tangente 135?

Replace the strap using two tools: a spring bar tool or small rounded spatula to gently lift the spring bar. Insert the spring bar into the lateral slots on the case, inserting the new strap from underneath. Operate with precision to avoid scratching the steel.

Are aftermarket straps compatible with the 135?

Yes, provided they feature 19 mm lug width. Not all manufacturers offer this dimension: always verify specifications before purchase. A 20 mm or 18 mm strap will not fit correctly into the case lugs.

How long does a leather strap last on the Tangente 135?

With vegetable tanning and moderate wear, shell cordovan lasts 5-7 years before replacement becomes necessary. Vegetable-tanned calf lasts 3-5 years. Longevity depends on sun exposure, humidity, and frequency of use. Regular maintenance with specialist creams extends lifespan.
