Frequently asked questions

What is the lug width of the Schwarz Etienne Roma WRO16MS31RB01AA?

The lug width is 16 millimetres. This dimension must be measured with precision using a digital calliper, positioning yourself perpendicular to the case plane between the two lugs. Accurate measurement is essential to ensure compatibility with bespoke straps.

What is the best strap for the Schwarz Etienne Roma WRO16MS31RB01AA?

For this rose gold model, we recommend alligator in vegetable tanning, dark brown, or shell cordovan. These materials dialogue with the nobility of the rose gold without competing aesthetically. Calf leather with fine grain is a valid alternative for those prioritising comfort and long-term wrist adaptation.

How do I change the strap on the Schwarz Etienne Roma WRO16MS31RB01AA?

Use a spring bar removal tool to gently lift the internal spring mechanism. Position the watch on a soft surface to avoid scratching the rose gold. Remove the old strap and insert the new one, aligning the lugs precisely with the pin axes. Verify that the spring bar is fully seated in its housing.

Are aftermarket straps compatible with the Schwarz Etienne Roma WRO16MS31RB01AA?

Yes, provided they respect the 16-millimetre lug width specification. Milano Straps offers a comprehensive range of bespoke 16mm straps in leather, NATO fabric, and rubber, constructed according to rigorous manufacturing standards and compatible with the geometry of Schwarz Etienne lugs.

How long does a leather strap last on the Schwarz Etienne Roma WRO16MS31RB01AA?

Durability depends on material and usage patterns. Alligator and shell cordovan in vegetable tanning, if subjected to regular maintenance and protection from humidity and direct sunlight, maintain structural integrity for 5–8 years. Calf leather tends to develop creasing earlier, around 3–4 years of daily wear. FKM rubber offers superior durability, 8–10 years, with degradation occurring primarily aesthetically.
