Frequently asked questions

What is the lug width of the Nomos Glashütte Tangomat 601?

The Tangomat 601 features a lug width of 20 mm. This is an international standard dimension for medium-sized watches and is compatible with a wide range of aftermarket straps. Lug width is measured by positioning a digital calliper across the exterior of the case's lug guides; for the Tangomat, the measurement should be 20.00 ± 0.2 mm to ensure optimal fit.

What type of strap is recommended for the Tangomat 601?

The Tangomat 601 pairs ideally with premium leather straps: vegetable-tanned alligator, shell cordovan, or grained calf leather. Alligator with regular grain complements the minimalist Bauhaus aesthetic of the case, while shell cordovan offers superior density and develops a rich patina over time. For more casual wear, NATO straps in technical textiles provide a versatile and practical alternative.

How do I change the strap on my Tangomat 601?

The Tangomat 601 is supplied by Nomos with a calf leather strap fitted with a push-button deployante clasp. Removal requires no tools: simply apply controlled pressure to the clasp to disengage it from the case lugs. Installation of a new strap is accomplished by reversing this process, ensuring the lug width is exactly 20 mm and the metal guides accept the new strap uniformly.

Can I use an aftermarket strap compatible with my Tangomat 601?

Yes, the Tangomat 601 accommodates any strap with a 20 mm lug width. It is essential to verify that the strap width at the lugs is precisely 20.00 mm and that the material is compatible with the original clasp (typically a push-button deployante). We recommend checking the technical specifications provided by the strap manufacturer before purchase.

How long does a leather strap last on the Tangomat 601?

The lifespan of a leather strap depends on the tanning method and intensity of use. A grained calf leather strap typically lasts 2-3 years with daily wear. Vegetable-tanned alligator and shell cordovan offer superior durability, lasting 4-5 years, due to the density of the material. Regular maintenance, including cleaning and the application of natural oils, significantly extends the useful life of the strap.
