Strap for Orion Neomatik 39

The lug width of the Nomos Glashütte Orion 340 is 19 mm. This measurement represents the internal distance between the two lug pins and must match exactly to ensure proper strap adaptation without forcing or excessive play.

For the Orion 340, straps in alligator leather with fine grain, vegetable-tanned calf, or NATO-style textile are ideal. Alligator amplifies the Bauhaus rationality of the design, vegetable-tanned calf develops a natural patina over time, and NATO offers everyday versatility. Avoid overly structured materials that contradict the watch's constructive simplicity.

Use a spring bar removal tool to apply gentle downward pressure on one of the lug pins. The internal spring will compress, releasing the pin from its seat. Repeat on the other side. Insert the new pins into the holes of the new strap and reinsert into the case using the same procedure, ensuring the strap is perfectly aligned.

Yes, any strap with a 19 mm lug width is compatible with the Orion 340. Quality artisanal straps often offer superior construction and materials compared to originals. Ensure the strap has been precisely measured to 19 mm and that the holes have been made slightly larger (0.5 mm) to allow smooth movement of the pins.

The lifespan of a leather strap depends on the tanning method and daily use. A vegetable-tanned calf typically lasts 3-5 years with regular wear, developing a fine patina. Alligator, being more resistant, can last 6-8 years. Constant exposure to humidity and perspiration accelerates wear; regular maintenance (gentle cleaning, drying) extends its useful life.
