Strap for Atum Pure L DLC / Blue

The lug width of the Moritz Grossmann Atum MG-001113 is precisely 18 millimetres. This dimension is crucial for aftermarket strap compatibility: an incorrect lug width poses mechanical damage and visual discord risks. To verify correct measurement, position the watch parallel to a flat surface and measure the distance between the two inner attachment points of the lugs.

The most coherent strap choice for the Moritz Grossmann Atum's minimalist aesthetic is vegetable-tanned calfskin. Its patina evolves naturally over time, creating a fascinating chromatic dialogue with the steel case finishing. Alternatively, natural alligator enriches the aesthetic character, whilst NATO and quality rubber straps offer pragmatic solutions for sportier applications.

Strap change occurs through the case lugs. Procure a springbar tool to gently elevate the elastic springbar from the lug seats. Remove the old strap, insert the new one ensuring the 18mm lug width aligns correctly with the seats, and reposition the springbar confirming secure engagement on both sides. Avoid excessive pressure which might scratch the case.

Yes, all 18mm lug width straps are compatible with the Moritz Grossmann Atum MG-001113. Ensure the strap has been dimensioned correctly for this exact lug width. Vegetable-tanned calfskin, alligatore, NATO and quality rubber straps prove particularly harmonious with this model's aesthetic character. Always verify lug width specifications before purchase.

Leather strap longevity depends on usage intensity and construction quality. A superior-quality calfskin or alligator strap, subjected to moderate use (4–5 days weekly), maintains structural and aesthetic integrity for 3–5 years. The patina ages favourably, creating a natural marbling effect. Daily intensive use, particularly in humid environments, reduces this duration. NATO and rubber straps demonstrate superior resistance to wear and atmospheric agents.
