Nomos Glashütte
Orion 384.S7— lug 19mm

The lug width of the Nomos Glashütte Orion 384.S7 is 19 mm. This width is specific to the 38 mm Orion model and is measured between the inner edges of the two lateral attachment seats. To verify the measurement, place a ruler perpendicular to the pin line: the distance should be 19 mm on both sides of the case.

For the Orion 384.S7, we recommend a cognac brown alligator strap or shell cordovan, which emphasise the Bauhaus aesthetic and constructive purity of the movement. For heavier daily wear, black vegetable-tanned calf or a cotton NATO strap maintain versatility. FKM rubber offers contemporary durability if the watch is worn in technical or sports environments. All straps must feature 19 mm lug width for perfect fit.

Changing the strap requires a spring bar remover tool. Position the watch on a soft surface, insert the tool tip into the small hole of the lug pin to compress the internal spring, and extract the pin. Repeat on both sides of the case. Align the new strap holes with the seats and reinsert the pins until they click into place. Verify the strap is secure by pulling gently.

Yes, you may use aftermarket straps provided they have a 19 mm lug width and the spring bars are compatible with the case seats. Artisanal quality straps preserve the aesthetic and constructive value of the watch. We recommend verifying that the strap has been tested on 38 mm models to avoid excessive pressure on the case.

A quality leather strap (alligator, cordovan, vegetable-tanned calf) typically lasts 3–7 years with daily wear, depending on frequency of use and care. Shell cordovan straps tend to last longer, developing a fascinating patina. Longevity also depends on ambient humidity and cleaning frequency. An FKM rubber strap offers superior resistance in demanding environments, with a lifespan of 5–10 years. Rotating among multiple straps extends the overall lifespan of each.
