Frequently asked questions

What is the lug width of the Rolex Milgauss 116400GV-0002?

The Rolex Milgauss 116400GV-0002 features a lug width of 20 mm. This is the distance between the two lugs (or pins) on the case where the strap attaches. It is essential to measure this dimension accurately using a digital calliper to ensure proper strap compatibility.

Which strap is most suitable for the Rolex Milgauss 116400GV-0002?

For the Milgauss 116400GV-0002, alligator leather in brown tones or shell cordovan represent the most elegant choices, as they create aesthetic balance with the Verd Antique dial and stainless steel case. For a more informal approach, vegetable-tanned calf leather offers softness and notable ageing potential. Rubber straps maintain the technical and scientific dimension of the watch.

How do I change the strap on the Rolex Milgauss 116400GV-0002?

To change the strap, use a dedicated tool (a thin lever or spring bar removal tool) to push the elastic pins inward that secure the strap to the case. Remove the old strap by aligning it perpendicularly to the lugs, then insert the new strap in the same manner, ensuring the pins lock correctly on both sides.

What aftermarket strap compatibility exists for the Milgauss 116400GV-0002?

Any strap with a 20 mm lug width is compatible with the Milgauss 116400GV-0002. On MilanoStraps.it, you can filter the collection for 20mm straps and find artisanal leather straps in premium leather, shell cordovan, alligator, and vegetable-tanned materials. Compatibility is guaranteed by correctly measuring the lug width.

How long does a leather strap last on the Rolex Milgauss 116400GV-0002?

The longevity of a leather strap depends on the material and daily usage. A quality alligator or shell cordovan strap, with proper care, lasts 3-5 years of regular use. Vegetable-tanned calf leather can last 2-4 years. A rubber strap has an extended lifespan of up to 5-7 years. The Casati Milano artisanal guarantee covers 18 months against manufacturing defects.
