FAQ

What is the lug width of the Schwarz Etienne Roma WRO17MA27RB21AA?

The lug width is exactly 17mm, measured between the lateral pins that secure the strap. This dimension is specific to the Roma model and is essential for ensuring mechanical compatibility without gaps or play. Even a minor discrepancy renders the strap unusable.

Which strap is best suited to the Schwarz Etienne Roma WRO17MA27RB21AA?

An alligator with vegetable tanning in cognac or a vegetable-tanned calf leather represent the optimal choice from both aesthetic and behavioural standpoints. Leather develops a natural patina over time, amplifying the warmth of rose gold. For versatile use, consider also a NATO in nylon ripstop fabric or an FKM rubber strap for aquatic activities.

How do I change the strap on the Schwarz Etienne Roma WRO17MA27RB21AA?

The change requires a spring bar tool (supplied with our straps). Position the tool tip in the small hole of the spring present at one end of the lug, compress gently to release the pin, remove the old strap, insert the pin into the new strap and release. Proceed on the other lug with the same caution. The process takes just a few minutes and requires no technical expertise.

Is an aftermarket strap compatible with the Schwarz Etienne Roma WRO17MA27RB21AA?

Yes, provided the lug width is exactly 17mm. Any strap in our catalogue with this measurement is mechanically compatible. We recommend choosing the material based on actual use and personal aesthetics, not on fashion trends.

How long does a leather strap last on the Schwarz Etienne Roma WRO17MA27RB21AA?

A quality leather strap (alligator or vegetable-tanned calf) has an average lifespan of 3 to 5 years with regular daily use. Longevity depends on frequency of use, climate, moisture exposure and maintenance care. A vegetable-tanned leather can be restored or revalued over time, developing a patina that enhances its aesthetic value.
