The Atum MG-000807, seen from the bench

The Moritz Grossmann Atum MG-000807 features a 41mm rose gold case and is powered by the in-house Moritz Grossmann caliber 100.1 movement, assembled in Glashütte. The watch features a three-hand display with small seconds subdial, characteristic of Saxon watchmaking tradition. The 20mm lug width is a proportional specification critical for maintaining visual balance on the wrist, requiring careful strap selection to avoid undersizing or oversizing issues that would compromise the watch's aesthetic harmony.

Frequently asked questions

What is the exact lug width of the Moritz Grossmann Atum MG-000807?

The lug width of the Moritz Grossmann Atum MG-000807 is precisely 20mm. This measurement is critical for maintaining correct proportions on the 41mm case at the wrist. Always measure internally between the spring bar posts to obtain the accurate dimension.

Which strap do you recommend for the Moritz Grossmann Atum MG-000807?

For the Moritz Grossmann Atum MG-000807, we recommend natural alligator (cognac or pearl grey) for understated elegance, or vegetable-tanned leather that ages in harmony with rose gold. Black rubber is ideal for daily wear. NATO offers maximum versatility on informal registers.

How do I change the strap on the Moritz Grossmann Atum MG-000807?

Position the watch on a soft surface with the case facing upward. Using a spring bar tool, gently push the posts toward the center of the case from inside, one at a time. Remove the old strap. Insert the new strap ensuring the spring bars lock securely at the case ends. Verify the strap is exactly 20mm in width.

Is an aftermarket strap compatible with the Moritz Grossmann Atum MG-000807?

Yes, any strap measuring 20mm with straight ends is compatible with the Moritz Grossmann Atum MG-000807. Ensure the strap is measured precisely between the spring bar holes (20mm internal). Avoid lug-mounted or pre-formed lug straps that would not fit the case.

How long does a leather strap last on a Moritz Grossmann Atum?

A quality leather strap (alligator or vegetable-tanned leather) typically lasts 2–4 years with regular daily use. Longevity depends on exposure to moisture, perspiration, and sunlight. Vegetable-tanned leather ages, developing patina, whilst alligator maintains structure longer. We recommend replacement when leather begins cracking at the edges.
