Frequently asked questions

What is the lug width of the Mühle Glashütte Lunova M1-43-06-LB?

The Mühle Glashütte Lunova M1-43-06-LB features a lug width of 20 mm. This measurement is the distance between the spring bars that attach the strap to the case lugs. It is essential to verify this specification before purchasing a replacement strap to ensure perfect compatibility.

Which strap is most suitable for the Mühle Glashütte Lunova M1-43-06-LB?

For the Lunova M1-43-06-LB, we recommend shell cordovan straps in cognac for refined occasions, vegetable-tanned leather in black for daily wear, or dark blue NATO straps to emphasise its sporting heritage. The choice depends on your intended usage and the dial's blue tone you wish to enhance.

How do I change the strap on my Mühle Glashütte Lunova M1-43-06-LB?

Use a spring bar tool to remove the pins situated at the lugs. Insert the tool into the small hole on the pin's side, gently press upward to decompress the internal spring, and extract the pin. Repeat on the opposite side. To install the new strap, align the holes and reinsert the pins until they seat flush, confirming secure placement.

Can I use aftermarket straps on a Mühle Glashütte Lunova M1-43-06-LB?

Yes, any strap with a 20 mm lug width is compatible. MilanoStraps offers a curated selection of artisanal straps in leather, fabric, and rubber, all tested for this model. Italian artisanal quality ensures superior construction and finishing compared to generic alternatives.

How long does a leather strap last on a timepiece like the Lunova M1-43-06-LB?

A high-quality, vegetable-tanned leather strap typically lasts 3–5 years with moderate daily wear. Durability depends on usage frequency, moisture exposure, and wearing habits. MilanoStraps recommends periodic conditioning with natural balms to extend strap lifespan.
