FAQ

What is the lug width of the Moritz Grossmann Atum MG-001191?

The Moritz Grossmann Atum MG-001191 features an 18mm lug width. This measurement was selected by Glashütte to ensure optimal proportions between the 41mm case and strap, maintaining both aesthetic balance and ergonomic comfort. Any strap with an 18mm lug width is compatible with this model.

What is the best strap material for the Moritz Grossmann Atum in rose gold?

The best strap depends on intended use and personal preference. For classical elegance, we recommend dark brown alligator or vegetable-tanned leather, which dialogue naturally with rose gold. For everyday versatility, a navy NATO or dusty grey leather. For maximum functionality, black rubber. Shell cordovan represents the absolute pinnacle for those seeking tactile and aesthetic heritage.

How do I change the strap on my Moritz Grossmann Atum MG-001191?

The process is straightforward. Obtain a spring bar removal tool, or visit a qualified watchmaker. Position the tool against the internal spring of the lug pin and gently press to disengage the spring from its seat. The pin will extract easily. Insert the new strap by aligning the holes to the case ends, then reinsert the pin until you hear the spring click into place. Repeat on the opposite side.

Can I use an aftermarket strap on my Moritz Grossmann Atum MG-001191?

Yes, any 18mm strap is compatible. High-quality aftermarket straps, such as those offered by Milano Straps, maintain the same aesthetic and constructive excellence as the case. Ensure the strap is crafted from noble materials (alligator, vegetable-tanned leather, shell cordovan) and that the lugs are robust to guarantee security and durability over time.

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

A quality leather strap (alligator, leather, shell cordovan) typically lasts 5-8 years with daily use, depending on care level and environmental exposure. Vegetable-tanned leather ages gracefully, developing patina and character. To extend longevity, avoid prolonged exposure to water, extreme humidity, and direct sunlight. A robust NATO fabric strap can last 10+ years with minimal maintenance.
