Frequently Asked Questions

Will an 18mm strap fit my Rolex, Vacheron Constantin, and Breguet?

Yes. 18mm is compatible with classic models: Rolex 124200, Vacheron Constantin 8005 /120R and /120A, Breguet 5177BA and 5447BR. Always verify your lug holes before ordering; tolerance can be ±0.2mm.

What's the difference between nubuck and suede for a strap?

Both are napped finishes. Nubuck comes from the outer side of the hide (more durable), suede from the inner side (more delicate). For 18mm, nubuck is ideal if you want durability; suede if you want pure softness.

Can I customize the strap length?

Absolutely. Every 18mm strap from Milano Straps is built to measure. Give us the length from buckle to longest hole, and we'll craft yours exact.

Which leather for an 18mm strap that lasts?

Alligator, ostrich, and Italian leather are the most durable. Alligator is top tier for resistance; Italian leather ages beautifully. Saffiano and calf are robust but more contemporary in character.

How do I care for an 18mm suede or nubuck strap?

Brush regularly with a soft eraser to maintain the nap. Avoid direct water. If stained, treat with suede-specific leather cleaner. Noble leathers like alligator and ostrich require less maintenance.
