Frequently asked questions

What is the lug width of the Moritz Grossmann Atum MG-000685?

The lug width of the Moritz Grossmann Atum MG-000685 is 18 millimetres. This measurement refers to the distance between the two side lugs connecting the case to the strap. It is essential to verify this dimension before purchasing an aftermarket strap to ensure correct and secure fitment on the watch.

Which strap material is recommended for the Atum MG-000685?

For the Atum MG-000685, we recommend straps in alligator leather or vegetable-tanned calf leather, which reflect the aesthetic purity of the timepiece. For more versatile daily wear, a NATO strap or natural vulcanised rubber carapace offers functionality without stylistic compromise. Your choice depends on the intended use and desired level of formality.

How do I change the strap on my Moritz Grossmann Atum?

To change the strap, equip yourself with a spring bar remover tool or a small flat lever. Place the Atum on a protected surface, then gently push the side spring bar upwards to extract it from the case. Repeat the operation on the second bar. Insert the new spring bars into the strap lugs and slide the strap onto the case attachments, then secure the spring bars by pushing them downwards until fully aligned.

Which aftermarket straps are compatible with the 18mm lug width of Moritz Grossmann?

All straps with an 18 millimetre lug width are compatible with the Moritz Grossmann Atum MG-000685, provided the spring bars are of standard diameter (1.8 mm) and the length is suitable for your wrist. On milanostraps.it you will find a complete selection of 18mm straps in leather, NATO and rubber, all verified for compatibility and artisanal quality.

How long does a leather strap last on the Atum MG-000685?

The lifespan of an artisanal quality leather strap depends on frequency of use, climatic conditions and maintenance. A well-maintained alligator or vegetable-tanned calf leather strap can last 3-5 years with moderate daily wear. Periodically treating the leather with specific oils and protecting it from excessive moisture significantly extends its life. The patina that leather naturally develops over time is desirable: it testifies to the noble wear of the object.
