Strap for Atum Pure M DLC / Blue

The lug width of the Moritz Grossmann Atum MG-000712 is precisely 20 millimetres. This dimension is critical for strap selection: the strap must have an internal width of exactly 20mm to fit correctly into the case lugs without lateral movement. Accurate measurement with a calliper is recommended before purchasing an aftermarket strap.

Given the rigorous nature and Germanic heritage of the Moritz Grossmann Atum MG-000712, a vegetable-tanned alligator strap of museum quality is recommended. Cognac brown with a brushed steel deployante represents the most coherent pairing: the regular grain of alligator dialogues with the case finish, whilst cognac introduces a sophisticated and durable chromatic note over time. Alternatively, Italian vegetable-tanned calf in dark brown (testa di moro) offers natural colour evolution and superior tactile experience.

To change the strap, you must remove the spring bars that connect the case to the strap. Use a strap removal tool or a small metal pin to push inward the spring bar, thereby releasing the strap. Once both bars are removed, the old strap detaches and the new 20mm strap is inserted into the case holes until it clicks into position. For delicate operations, it is advisable to consult a professional watchmaker or the manufacturer's service centre.

Yes, absolutely. Milano Straps offers a collection of artisanal 20mm straps compatible with the Moritz Grossmann Atum MG-000712. All straps are crafted with the same care and constructive precision as the watch itself, using excellence materials (alligator, vegetable-tanned calf, FKM rubber, waxed NATO canvas). Always verify before purchase that the lug width corresponds exactly to 20mm. Aftermarket straps do not compromise the warranty if changed correctly.

A quality leather strap (alligator, calf) worn daily on a Moritz Grossmann Atum MG-000712 has an average lifespan of 4–7 years, depending on intensity of use and care applied. Moisture, perspiration and sun exposure accelerate ageing. An FKM rubber strap typically lasts 8–10 years without significant loss of elasticity. Durability extends considerably if the strap is rotated with others (not worn consecutively). Vegetable tanning, though more delicate than modern tannage, develops a fascinating patina and remains structurally intact even after 5–6 years of intensive use.
