Strap for Lunova Datum Black / Strap

The lug width of the Mühle Glashütte Lunova M1-43-16-LB is 20 mm, measured between the lug tips of the case. This dimension is standardised and ensures compatibility with all 20 mm strap options available in the Milano Straps catalogue.

For the Lunova we recommend alligator leather for formal wear (enhances Saxon heritage), vegetable-tanned calf for natural patina development, NATO for chromatic versatility, and rubber with deployante for technical configuration. Choice depends on usage context and personal aesthetic preference.

The strap is changed by removing the spring bar that passes through the case lugs. Use a spring bar tool to extract the bar with gentle lateral pressure, then insert the new strap by pushing the bar into the opposite seat until it clicks into place. The operation takes minutes and can be performed manually with care.

Any strap with a 20 mm lug width is mechanically compatible. Milano Straps provides a curated selection of 20 mm straps in premium materials (alligator, calf, shell cordovan, NATO, rubber), all selected for aesthetic quality and durability when paired with luxury watches.

A quality leather strap (alligator, calf aniline) lasts 3-5 years with moderate daily wear. Longevity depends on frequency of use, moisture exposure, leather pH, and maintenance. Vegetable-tanned leather develops patina over time, a sign of natural ageing. Regular maintenance (cleaning, conditioning) extends lifespan.
