Strap for Tangente 38 Datum Kanari

The lug width (ansa width) of the Nomos Glashütte Tangente 179.S6 is 18mm. This is the internal distance between the two horizontal lugs that attach the strap to the case. To verify, remove the original strap and measure the space between the lugs: you will find exactly 18mm, which allows you to fit any high-quality artisanal strap.

For the Tangente 179.S6, we recommend a strap in alligator with vegetable tanning or martelled calf (fine grain): both enhance the rational Bauhaus aesthetic of the case. Alligator emphasises sobriety through its structured grain; calf offers greater versatility whilst maintaining formal elegance. For those seeking daily practicality, a NATO strap in Cordura canvas remains a coherent aesthetic choice.

To change the Tangente 179.S6 strap, obtain a spring bar tool (small, flat instrument). Insert the tip into the slot beneath the lug and gently push upward to free the pin at one end, then slide the old strap outwards. Repeat on the other side. To install the new strap, insert the pins into the case lugs and push until you hear a click. The operation takes a few minutes and requires no specialised tools.

Any artisanal strap with an 18mm lug width is compatible with the Tangente 179.S6. At milanostraps.it you will find a curated selection of straps in alligator, calf, shell cordovan, rubber and canvas, selected for construction quality and finish. Compatibility is guaranteed by the standardisation of lug width (18mm) without need for adapters.

A high-quality leather strap (alligator with vegetable tanning, martelled calf) has an average lifespan of 3–5 years with moderate daily use, stretching over time to conform to your wrist shape. Alligator ages beautifully and develops a fascinating patina; calf is more resistant to mechanical wear. To extend lifespan, avoid prolonged exposure to moisture and periodically rotate different straps. Replacement is not maintenance, but an opportunity to reinterpret your Tangente aesthetically.
