The Heritage

The Nomos Glashütte Tangente 123.S8 is a 32.80 mm stainless steel case watch powered by the manual-wind Alpha caliber. It features an asymmetrical dial with off-center small seconds, a domed case, and a crown positioned at 3 o'clock. The 17 mm lug width is a distinctive measurement that differs from industry standards and requires specific aftermarket strap compatibility. Water resistance is rated to 30 meters.

FAQ

What is the lug width of the Nomos Glashütte Tangente 123.S8?

The lug width of the Tangente 123.S8 is 17 millimetres. This specific intermediate measurement refers to the inner distance between the two lugs (pins) that support the strap. Precision in measurement is essential to ensure correct fitting and aesthetic alignment of the replacement bracelet.

Which strap is most suitable for the Nomos Glashütte Tangente 123.S8?

The ideal strap for the Tangente 123.S8 is vegetable-tanned calf leather, preferably with a fine grain finish and in dark brown or cognac tones. This choice respects the Bauhaus philosophy of the watch, allowing for natural patina development over time. Alternatively, alligator leather for greater refinement, a nylon NATO strap for daily wear, or technical rubber for sports utility.

How do I change the strap on my Tangente 123.S8?

To change the strap, you will need a spring bar removal tool or should consult a specialist horologist. Position the watch to access the underside of the lug, gently insert the tool to compress the internal spring of the pin, then extract the pin itself. Repeat on the other side. The new strap must have an exact lug width of 17 millimetres to ensure correct installation.

Are there aftermarket straps compatible with the Tangente 123.S8?

Yes, high-quality aftermarket straps are specifically designed for 17-millimetre lug widths. It is essential to verify that the supplier explicitly certifies compatibility with this specific measurement. Straps are available in vegetable leather, alligator, NATO fabric, and FKM rubber. Milano Straps offers a curated collection of 17mm straps ready for shipment and customisable online.

How long does a leather strap last on the Tangente 123.S8?

A high-quality leather strap, subjected to moderate daily use, maintains structural integrity for 2 to 4 years. Longevity depends on intensity of use, environmental humidity, tanning method, and maintenance. Vegetable-tanned leather straps soften and develop patina over time, a natural process appreciated by enthusiasts. An alligator or shell cordovan strap offers superior durability, often exceeding 5 years. Periodic cleaning with a damp cloth and protection with transparent wax will extend its lifespan.
