FAQ

What is the lug width of the Moritz Grossmann Atum MG-000709?

The lug width of the Moritz Grossmann Atum MG-000709 is 20mm. This measurement represents the distance between the spring bar lugs on the case, which are the anchoring points for the strap. A compatible strap must have an exact width of 20mm at the attachment point to ensure secure installation and zero play.

Which strap pairs best with the Moritz Grossmann Atum MG-000709?

For the Moritz Grossmann Atum MG-000709, we recommend museum-grade alligator for maximum aesthetic impact, or English calf with vegetable tanning and brushed steel deployant clasp for daily versatility. Alternatively, heavy canvas NATO or shell cordovan offer practical construction whilst maintaining the visual authority required by this German timepiece.

How do you change the strap on a Moritz Grossmann Atum?

The strap on a Moritz Grossmann Atum is changed using a simple spring bar removal tool or appropriate small lever. Position the tool under the spring bar and apply slight pressure to retract the internal spring, then extract the bar. Next, align the new strap with the lug holes and repeat the procedure on the opposite side. The process takes approximately two minutes for experienced users.

Can I fit an aftermarket strap from a different brand on the Moritz Grossmann Atum MG-000709?

Yes, any strap with spring bar attachment and 20mm lug width is compatible with the Moritz Grossmann Atum MG-000709. There are no proprietary construction specifications that would require dedicated straps. We recommend artisanal quality straps manufactured in Italy, as they ensure finishing standards coherent with the aesthetic severity of the timepiece.

What is the average lifespan of a leather strap on a Moritz Grossmann Atum?

A quality leather strap (alligator or calf with vegetable tanning) mounted on a Moritz Grossmann Atum typically lasts 5-7 years with moderate daily use. Longevity depends on frequency of wear, moisture exposure, periodic maintenance, and type of tanning. A strap with a grainy or pebbled finish tends to age more subtly than a polished one, as patina accumulates more discretely.
