Atum MG-001122— lug 18mm

The lug width of the MG-001122 is 18 millimetres, measured between the two internal lugs that attach the strap to the case. It is important not to confuse lug width with case width. To verify the correct measurement, use a digital calliper positioned exactly between the two attachment lugs.

For the MG-001122, we recommend alligator or vegetable-tanned calf leather, which enhance the frosting of the movement visible through the caseback. For more versatile everyday use, FKM rubber straps or cotton NATO straps offer practicality without aesthetic compromise. The choice depends on intended use: formal for alligator, sport-elegant for NATO, robust everyday wear for rubber.

Changing the strap on the MG-001122 is straightforward: use a spring bar tool to gently push the small elastic pin that holds the strap in place. Insert the tool tip into the small hole on the inside of the pin, push inward, and the pin will retract enough to remove the old strap. Align the new strap's holes with the lugs, then release the pin allowing it to snap into position. Perform the operation with care to avoid scratching the case.

Absolutely. Any strap with an 18 millimetre lug width is compatible with the MG-001122. Milano Straps offers a complete selection of artisanal 18mm straps: alligator, shell cordovan, calf, NATO and technical rubber. Compatibility is guaranteed by ISO standard, but we recommend verifying that the buckle deployante suits the case thickness for a perfect fit.

A high-quality leather strap, such as alligator or vegetable-tanned calf, has an estimated lifespan of 3 to 7 years with regular use and proper maintenance. Longevity depends on humidity exposure, perspiration, appropriate cleaning and storage. A well-maintained strap will develop a fascinating patina over time. To extend durability, occasionally apply a specific leather conditioner and store the strap in a dry place. If the strap is damaged, it can be easily replaced without affecting the watch's value.
