FAQ
What is the lug width of the Nomos Glashütte Tangente 115?
The lug width of the Nomos Glashütte Tangente 115 is precisely 18 millimetres. This is an exact technical specification: the distance between the case terminals where the strap inserts measures 18mm, a historical proportion that maintains visual balance on the 35mm-diameter watch. It is important to verify this measurement before purchasing an aftermarket strap, as 18mm is an increasingly uncommon width in the contemporary market.
Which type of strap is most suitable for the Tangente 115?
For the Tangente 115, straps in noble leather such as fine-grained alligator or vegetable-tanned calf are recommended, as they respect the minimalist Bauhaus aesthetic. Alligator develops an elegant patina over time, whilst calf offers tactile character and sustainability. NATO straps in grey or sand-beige canvas are excellent for versatility. For formal occasions, a natural rubber strap with proportionate deployante preserves elegance without the constraints of leather.
How do I change the strap on a Nomos Glashütte Tangente 115?
The strap on the Tangente 115 is replaced via the spring bars (lugs) that connect the strap to the case. Use a dedicated tool to gently remove the spring bar from its seat, working from both sides. Once the spring bars are removed, the old strap detaches easily. Insert the new spring bars into the case holes and new strap, ensuring they are firmly secured. If you are inexperienced, consult a specialist atelier such as Casati Milano for the operation.
Can I use a quality aftermarket strap on this watch?
Absolutely. A quality aftermarket strap constructed with an 18mm lug width is perfectly compatible with the Tangente 115 and represents an opportunity to personalise the watch according to your style. Specialist strap manufacturers offer noble materials such as alligator, vegetable-tanned calf, and natural rubber. The key is to verify that the lug width is exactly 18mm and that construction quality is consistent with the value of the watch.
How long does a leather strap last on a watch like the Tangente 115?
A noble leather strap under regular wear has an average lifespan of 4-7 years, depending on intensity of use, moisture exposure, and maintenance. An alligator strap tends to last longer than calf, retaining structural integrity despite patination. Natural ageing is part of the beauty of these materials: a quality leather develops a patina that tells the wearer's story. Periodic maintenance—application of specific balms and storage away from extreme humidity—significantly extends the strap's useful life.
