FAQ

What is the lug width of the Moritz Grossmann Atum MG-001088?

The lug width of the Moritz Grossmann Atum MG-001088 is 20 millimetres. This technical specification represents a deliberate design choice by the Saxon manufactory, intended to maintain volumetric equilibrium between the 41-millimetre case and the suspension devices. To verify this measurement, use a digital calliper, measuring the internal distance between the two opposite lugs.

What is the best strap for the Moritz Grossmann Atum?

The optimal strap depends on intended use. Alligator in neutral tones (brown, black, slate grey) offers stylistic coherence with the neoclassical architecture of the case. Shell cordovan delivers a patina that evolves with wear. For everyday versatility, a dense, resilient rubber strap is the most practical choice. Vegetable-tanned leather represents a compromise between aesthetics and functionality, developing progressive patina development.

How do I change the strap on the Moritz Grossmann Atum MG-001088?

The strap is replaced via the spring bar (ansa springbar). Using a dedicated tool (spring bar tool), compress the internal spring mechanism and extract the bar from the lugs. Insert the new strap by correctly aligning the straps to the case holes and reinsert the bar until it locks securely. Verify that the bar is positioned correctly on both sides before wearing.

Which aftermarket straps are compatible with the 20mm lug width of the MG-001088?

All straps manufactured for 20-millimetre lug width are compatible with the Moritz Grossmann Atum. The range includes alligator, calf leather, shell cordovan, vegetable-tanned leather, rubber and NATO straps. Consult the specific 20mm lug width collection to ensure correct compatibility and verify that the chosen design does not compromise the aesthetic harmony of the case.

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

Durability depends on material type and usage intensity. An alligator strap, subject to regular wear and adequate maintenance, maintains aesthetic integrity for 4-6 years. Shell cordovan, owing to its density and resilience, may last 6-8 years. Vegetable-tanned leather tends to develop natural creasing with intensive use after 3-5 years, a phenomenon that characterises the evolutionary beauty of this material. High-quality rubber maintains elastic properties for 2-4 years before requiring replacement.
