Strap for Atum Pure M DLC / White

The Moritz Grossmann Atum MG-000587 features a lug width of precisely 20mm. This dimension is specific to the model and calibrated to the 41mm case geometry to preserve the original proportions. To verify compatibility with an aftermarket strap, measure the spacing between the lugs with a digital calliper: the distance must be between 19.8 and 20.2mm for proper installation without excessive play.

Strap selection depends on personal aesthetics and intended use. For maximum formal elegance, alligator with fine grain in dark brown or black complements the Bauhaus purity of the steel case without visual distraction. Vegetable-tanned calf leather offers a versatile alternative with natural ageing over time. For a sportive approach faithful to German watchmaking essence, Cordura NATO in navy blue or military green maintains design coherence. FKM rubber in dark grey suits professionals seeking absolute minimalism and everyday practicality. Shell cordovan remains the rarest solution for collectors desiring deep patina and material authenticity.

The Moritz Grossmann Atum MG-000587 is equipped with a standard two-lug attachment system. To change the strap: (1) position the watch with lugs facing upward; (2) use a spring bar remover to gently push the lug spring from one side; (3) extract the spring bar from its seat; (4) repeat the procedure for the opposite side; (5) insert the new spring bars into the new strap and reassemble. Recommendation: avoid hammers or heavy tools that could damage the steel case. If uncertain, contact an official Moritz Grossmann service centre.

Yes, any strap with a 20mm lug width is compatible with the Moritz Grossmann Atum MG-000587, provided it is constructed to precise tolerances. Milano Straps exclusively catalogues validated 20mm straps for this lug width, ensuring installation without play or misalignment. Avoid generic or uncertain-quality straps: imprecise lug width could compromise visual harmony and cause accelerated lug wear. For variants with deployant clasps, ensure the clasp depth is compatible with your wrist thickness and desired circumference.

Leather strap longevity depends on material quality, usage frequency and environmental conditions. A premium alligator or vegetable-tanned calf strap maintains mechanical properties for 3-5 years of moderate daily use. With occasional wear (2-3 times weekly), longevity extends to 5-7 years. Continuous exposure to moisture, perspiration and UV rays accelerates ageing: a leather strap exposed daily to these factors may require replacement within 2-3 years. Recommended maintenance: apply leather balm every six months, keep the strap dry and remove it before water immersion. Shell cordovan offers superior longevity (7-10 years) due to material density.
