Frequently asked questions

What is the lug width of the Schwarz Etienne Roma WRO15MS27RB21AA?

The lug width of the Schwarz Etienne Roma WRO15MS27RB21AA is 15mm. This measurement represents the internal distance between the two lugs of the case and is essential for identifying compatible straps. At Milano Straps, you will find a complete collection of 15mm straps specifically selected for this model.

What type of strap is best suited for the Roma WRO15MS27RB21AA?

For a watch of this caliber, we recommend a high-quality leather strap produced using vegetable tanning: alligator for ultimate nobility and durability, or calf leather for versatility and understated elegance. Alligator with natural patina pairs perfectly with rose gold, creating a dialogue of textures and colours that enhances the case geometry. For active contexts, a NATO or FKM rubber strap represents a functional alternative without aesthetic compromise.

How do you change the strap on the Schwarz Etienne Roma?

Changing the strap on the Roma WRO15MS27RB21AA is performed by removing the original lugs from the case pins. We recommend contacting a professional watchmaker equipped with a spring bar removal tool, as incorrect procedure could damage the case. Atelier Casati Milano provides both the change service and pre-assembled and tested straps, guaranteeing maximum precision.

Are aftermarket straps compatible with the WRO15MS27RB21AA?

Yes, any strap with a 15mm lug width is theoretically compatible with the Roma. However, only straps selected and certified by Milano Straps guarantee respect for the aesthetic proportions and construction quality that a Schwarz Etienne watch deserves. Technical compatibility does not always equate to aesthetic coherence: choose a strap that dialogues with the rose gold and the geometric philosophy of the case.

How long does a natural leather strap last on a watch like the Roma?

A strap made from premium leather with vegetable tanning has an average lifespan of 3-5 years with daily use, depending on UV exposure, perspiration and maintenance. Alligator, thanks to its dense fibrous structure, tends to last longer than calf leather. To extend the life of your strap, we recommend periodic cleaning with a slightly damp cloth and annual conditioning with natural oils. Milano Straps also offers strap restoration and regeneration services.
