Frequently asked questions
What is the lug width of the Nomos Glashütte Tangomat 602?
The Nomos Glashütte Tangomat 602 has a lug width of 20 mm. This measurement represents the distance between the two spring bars (attachment pins) of the watch. To verify this precisely, measure linearly from centre to centre of the pins, or remove the current strap and check the engraving on the spring itself.
Which strap material is recommended for the Tangomat 602?
For the Tangomat 602, we recommend three solutions: (1) alligator or vegetable-tanned calf leather, which develop aesthetically over time, creating unique patina; (2) pure textile NATO straps, ideal for emphasising the model's constructive austerity; (3) technical elastomers in fluoroelastomer rubber, for those requiring resistance in humid environments. The choice depends on daily use and the desired aesthetic result.
How do I change the strap on my Nomos Glashütte Tangomat 602?
The Tangomat 602 uses standard 20 mm spring bars. To replace the strap: (1) obtain a spring bar tool or pin remover; (2) compress the small spring on one of the pins to extract it from its seat; (3) repeat from the other side; (4) align the new strap and reinsert the pins until they click into position. Avoid hammers or improvised tools that could damage the case.
Can I use third-party aftermarket straps on my 602?
Yes, provided they meet the 20 mm lug width specification. Any strap designed for this width—regardless of brand—is compatible with the Tangomat 602. We recommend always verifying that the pins have the correct thickness (approximately 1.6 mm) and that the ends align perfectly without excessive play or friction.
How long does a leather strap last on the Nomos Glashütte Tangomat 602?
Durability depends on daily use and leather quality. A good-quality vegetable-tanned leather (vegetable calf, alligator) maintains structural integrity for 5–7 years with regular use, although visible patina and wear increase over time. Economy leather straps require replacement every 2–3 years. Maintenance (cleaning, drying, occasional conditioning) significantly extends durability.
