Frequently asked questions

What is the lug width of the Nomos Glashütte Tangente 580?

The lug width of the Nomos Glashütte Tangente 580 is 20mm. This measurement refers to the internal distance between the two lugs on the case. A compatible strap must be exactly 20mm wide to fit properly into the lugs without play or forcing.

Which strap is best suited for the Nomos Glashütte Tangente 580?

For the Tangente 580, straps in alligator or calf leather with vegetable tanning are ideal, reflecting the sober and timeless aesthetic of the watch. Alternatively, a NATO strap in heavy cotton canvas or an FKM rubber strap offers versatility and daily practicality whilst maintaining the discreet elegance of the Nomos proposition.

How do you change the strap on a Nomos Glashütte Tangente 580?

Use a spring bar removal tool, inserting the flat tip into the groove beneath the spring bar. Gently push upward to compress the internal spring, then pull the strap outward. For installation, insert the spring bar into the hole of the new strap, align it with the case lug and push until it clicks into place. Avoid forcing to prevent case damage.

Can you use aftermarket straps on a Nomos Glashütte Tangente 580?

Yes, absolutely. Many artisan manufacturers produce high-quality straps compatible with the 20mm lug width. The key is to verify that the strap is made from certified leather or premium materials and that it has the correct width. A well-crafted strap can significantly improve the comfort and wearability of the watch.

How long does a leather strap last on a Nomos Glashütte Tangente 580?

A quality leather strap with vegetable tanning can last 2-4 years with regular use, depending on frequency of wear and climatic conditions. Leather wears faster in humid environments or with excessive perspiration. A well-maintained strap, periodically treated with neutral balm, ages nobly developing a rich patina. Replacing the strap causes no damage to the watch whatsoever.
