Frequently asked questions

What is the lug width of the Moritz Grossmann Atum MG-001097?

The lug width of the Moritz Grossmann Atum MG-001097 is 20mm. This width was specifically chosen to maintain correct proportions relative to the 41mm case and ensure balanced wearability on medium-sized wrists. To verify compatibility, measure the distance between the inner points of the lugs: if it measures 20mm, any strap of the same width will fit perfectly.

Which strap type pairs best with the Moritz Grossmann Atum MG-001097?

For the Moritz Grossmann Atum, we recommend black or dark brown alligator for a durable formal aesthetic, or vegetable-tanned calf leather that develops a natural patina over time. If you seek versatility, a charcoal grey NATO or a satin FKM rubber strap are excellent choices for less formal contexts whilst maintaining the watch's technical elegance.

How do I change the strap on the Moritz Grossmann Atum MG-001097?

The Moritz Grossmann Atum uses standard 18-20mm spring bars. To change the strap: 1) place the watch on a soft surface; 2) use a spring bar tool to gently push the spring from inside; 3) extract the spring bar from the lug; 4) align the new strap's holes with the case pins; 5) reinsert the spring bar until you hear a click. If unsure, consult a qualified horologist.

Can I use a compatible aftermarket strap on the Moritz Grossmann Atum MG-001097?

Yes, any strap with 20mm lug width is compatible with the Moritz Grossmann Atum MG-001097. We recommend artisanal straps crafted from quality materials (alligator, Italian calf, shell cordovan) to match the watch's quality standards. Verify that the lugs are the same width and that spring bars are in good condition before replacement.

How long does a leather strap last on the Moritz Grossmann Atum MG-001097?

Durability depends on material, usage, and maintenance. An alligator or vegetable-tanned calf strap can last 5-10 years with daily wear if properly cared for (avoid excessive moisture, dry quickly if wet, condition the leather every 6-8 months). Shell cordovan, being more rigid, has similar longevity but requires a break-in period. An FKM rubber strap offers greater durability (8-15 years) but gradually loses lustre over time.
