Strap for Manual Fire

The lug width (or strap width) of the RG11-MF.90 is 20mm. This measurement represents the internal distance between the case attachment lugs. Verifying this specification before purchasing an aftermarket strap is essential, as an incompatible width can create mechanical stress on the case hinges.

Given the skeletonised case back of the RG11-MF.90, alligator straps in cognac or vegetable-tanned calf leather create the most sophisticated visual dialogue with the visible movement. For a more sporty aesthetic, NATO straps in neutral tones maintain focus on the mechanical architecture. Selection depends on intended use: formal, casual, or hybrid wear.

Strap replacement requires extraction of the spring bars (the small pins). Use a dedicated spring bar tool to depress the internal pin toward the case body, releasing one end of the strap. Repeat on the opposite side. Insert the new strap, aligning the holes with the lug seats, then re-insert the spring bars. Avoid improvised tools that risk scratching the rose gold case.

Yes, any strap measured at 20mm internal lug width is physically compatible. Build quality varies significantly, however. Straps from dedicated manufacturers such as Milano Straps guarantee precise tolerances and finishing standards consistent with your watch's pedigree. A substandard strap, despite fitting, diminishes the overall ownership experience.

A high-quality leather strap (alligator or vegetable-tanned calf) typically endures 3–5 years of daily wear, depending on perspiration exposure, humidity, and replacement frequency. Leather visibly ages—a patina many enthusiasts consider an aesthetic asset. Regular maintenance (gentle cleaning) extends longevity. Milano Straps offers restoration services for exceptional-quality straps.
