Metro 1109— lug 19mm

The lug width of the Nomos Glashütte Metro 1109 is 19 mm. This measurement is critical for compatibility with any aftermarket strap. To verify, measure the distance between the two horizontal attachment points on the case: it must be exactly 19 mm with no tolerance margins. The depth of the lug must also be respected to prevent accelerated wear.

For the Metro 1109, alligator leather in vegetable tanning is the most appropriate choice: the asymmetric grain complements the minimalist case without compromising its essence. Dark-toned alligator (dark brown, black) enhances dial legibility. Shell cordovan offers a patina that evolves with time, whilst vegetable-tanned calf provides daily durability. NATO straps in organic cotton are ideal for informal summer contexts.

To change the strap: 1) obtain a dedicated spring bar removal tool; 2) position it under the bar on one side of the case; 3) apply light inward pressure to compress the spring; 4) carefully extract the bar; 5) repeat on the other side; 6) insert the bar into the new strap, aligning the holes; 7) secure the bar into the case on both sides. Avoid sudden impacts that could compromise the lugs.

Yes, provided the lug width is exactly 19 mm and the lug depth is respected. High-quality bespoke straps have been specifically engineered for this width. We recommend against inexpensive synthetic material straps: they degrade the tactile and visual perception of the watch within weeks. Milano Straps offers straps in alligator, calf, and natural rubber compatible with this measurement.

A quality leather strap (alligator, shell cordovan, vegetable-tanned calf) typically lasts 5-7 years with daily wear. Longevity depends on factors such as sun exposure, humidity, frequency of wear, and periodic care. Vegetable-tanned leather straps tend to develop natural patina, improving aesthetics with age. Regular maintenance (gentle cleaning, occasional conditioning) significantly extends strap lifespan.
