Nomos Glashütte
Tangente 171— lug 18mm

The lug width of the Nomos Glashütte Tangente 171 is 18 millimetres. This measurement represents the internal distance between the two lugs on the case where the strap is attached. It is a common standard for compact watches, ensuring compatibility with a wide range of artisanal straps available on the market.

The Tangente 171, with its minimalist Bauhaus design and brushed stainless steel case, pairs exceptionally well with straps in alligator or shell cordovan with vegetable tanning. A natural alligator strap amplifies the lightness of the case, whilst a dark shade imparts gravitas. Shell cordovan in medium burgundy creates a sophisticated chromatic vibration. For more informal contexts, a grey-dark NATO strap in canvas or an FKM rubber strap offer versatility without compromising its character.

The strap is changed using a spring bar tool. Insert the flat tip of the tool gently into the small hole on the side of each lug, applying light pressure to compress the internal spring of the bar. Once compressed, the bar retracts, allowing extraction of the old strap. Proceed in reverse to fit the new strap: position the holes on the new strap in alignment with the spring bars, apply gentle pressure to secure them in place. Avoid sudden movements that could damage the case finishing.

Yes, the Tangente 171 accepts any strap with an 18-millimetre lug width. High-quality artisanal straps are entirely compatible: simply verify that the strap ends are shaped for an 18mm lug width. milanostraps.it straps, for instance, are available in various finishes and materials—alligator, calf, cordovan, NATO, rubber—all sized for this measurement. Compatibility ensures complete stylistic freedom without technical compromise.

A leather strap's durability depends on the material, usage, and maintenance. An alligator or shell cordovan strap with vegetable tanning, worn daily and subjected to natural drying cycles, can last 5–8 years before displaying significant signs of wear. Vegetable-tanned leather, unlike synthetic alternatives, improves over time, developing a natural protective patina. Factors such as sun exposure, perspiration, and humidity accelerate natural patina development. A canvas NATO strap, conversely, can last a decade or more if properly stored. Periodic maintenance—cleaning with a damp cloth, occasional conditioning with natural wax—substantially extends longevity.
