FAQ

What is the lug width of the Moritz Grossmann Atum MG-000499?

The lug width of the Moritz Grossmann Atum MG-000499 is 20mm. This measurement represents the distance between the two horizontal attachment pins on the lugs. To verify correctly, measure the free space between the pins, not the overall case width. All straps compatible with this specification fit perfectly onto the integrated lugs of this model.

Which strap is most suitable for the Moritz Grossmann Atum MG-000499?

To enhance the minimalist and geometric aesthetics of the Atum MG-000499, we recommend a black or cognac alligator strap, or calf leather with vegetable tanning. These materials preserve formal elegance and dialogue discretely with the brushed case finish. For a more sporty approach, a cotton or synthetic silk NATO strap maintains the piece's dignity. Shell cordovan in bordeaux or dark brown offers an extraordinary specular patina that develops over time.

How do I change the strap on the Moritz Grossmann Atum MG-000499?

The Atum MG-000499 utilises a standard attachment system with removable pins. Use a dedicated spring bar tool to push the small pin laterally inward, then extract the pin from the lug. Align the new strap's passant with the lugs, then reinsert the pin by pushing until you hear a click of closure. Verify that the strap is securely fastened before wearing the watch.

Can I use an aftermarket strap compatible with the Moritz Grossmann Atum MG-000499?

Yes, absolutely. The Atum MG-000499 accepts any strap with a 20mm lug width, provided it is manufactured to precise tolerances. Our artisanal 20mm straps guarantee perfect compatibility and offer the opportunity to personalise your watch's aesthetics. We recommend selecting moderate thicknesses (1.4-1.6mm) to maintain visual harmony with the case's contained profile.

How long does a leather strap last on the Moritz Grossmann Atum MG-000499?

Leather strap longevity depends on frequency of wear, climatic conditions, and material quality. A strap crafted from quality leather with vegetable tanning or alligator maintains structural and aesthetic integrity for 2-4 years with daily wear. Premium materials such as shell cordovan can exceed 5 years of durability. Regular maintenance—gentle cleaning and seasonal conditioning—significantly extends longevity.
