FAQ

What is the lug width of the Moritz Grossmann Atum MG-000465?

The lug width of the Moritz Grossmann Atum MG-000465 is 20mm. This measurement refers to the distance between the inner shoulders of the case attachment pins. Measuring the lug width correctly is essential to ensure that the strap fits perfectly without play or forcing.

Which strap is best suited for the Moritz Grossmann Atum MG-000465?

For the Atum MG-000465 in white gold, alligator represents the most natural choice. The fine and regular grain of the exotic leather complements the essential geometry of the case. Alternatively, vegetable-tanned calf leather offers a more contemporary aesthetic, whilst a silk-textured NATO strap allows casual wear without compromising quality.

How do I change the strap on a Moritz Grossmann Atum?

To change the strap, you must remove the lateral attachment pins using a dedicated tool (spring bar tool). Align the new strap to the case shoulders, insert the pins and ensure they are properly secured. Given the unconventional attachment of the Atum, we recommend consulting an expert to avoid damaging the white gold case.

Can I use an aftermarket strap on a Moritz Grossmann Atum MG-000465?

Yes, provided it has the correct lug width (20mm). Custom artisan straps offer greater control over quality and aesthetics. The unconventional attachment of the Atum makes it even more important to choose a strap crafted with precision by experienced artisans to preserve the integrity of the case.

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

The lifespan depends on the material and usage. High-quality alligator leather has a longevity of 3-5 years with regular maintenance. Vegetable-tanned calf varies from 2-4 years. Technical rubber lasts 4-6 years. Humidity and direct sun exposure accelerate ageing; periodic maintenance significantly extends the strap's lifetime.
