Nomos Glashütte
Orion 380.S1— lug 19mm

The lug width of the Nomos Glashütte Orion 380.S1 is 19 millimetres. This standard has been calculated to maintain harmonious proportions with the 38-millimetre case diameter. The lug width represents the distance between the two holes where the watch strap attachment springs are inserted.

For the Nomos Orion 380.S1, we recommend alligator straps with vegetable tanning for formal settings, French or Hermès calf for everyday versatility, and military NATO straps in neutral tones for those seeking practicality. The choice depends on intended use and personal aesthetic preferences. All straps must comply with the 19-millimetre lug width specification.

Changing the strap requires a dedicated spring bar removal tool to compress and extract the spring bars from the lateral case holes. Locate the two holes on the lugs, insert the spring bar tool, extract the old spring bars, and repeat the process with the new strap. The operation demands care to avoid scratching the case. If inexperienced, consultation with a specialised watchmaker is recommended.

Yes, provided the aftermarket strap respects the 19-millimetre lug width specification and is equipped with standard spring bars. Many specialised artisans produce 19mm straps in premium materials such as alligator, shell cordovan, and vegetable-tanned calf, available online through dedicated platforms.

A quality leather strap (alligator or vegetable-tanned calf) typically lasts 3–5 years of daily wear, developing an increasingly profound patina. Longevity depends on frequency of use, climatic conditions, perspiration, and maintenance. A strap protected from excessive moisture and periodically treated with specific balms ages more elegantly and lasts considerably longer.
