The lug width is 20mm. This width is determined by the case architecture and represents the distance between the metal lugs where the strap attaches. Any compatible strap must have an attachment width of exactly 20mm to ensure stability and proper alignment.

Alligator in bordeaux or cognac tones pairs beautifully with the 18k rose gold, enhancing the champagne dial. Vegetable-tanned calf leather with aged patina creates an elegant aesthetic continuity. For formal occasions, black shell cordovan remains the standard. The choice depends on intended use and personal color preferences.

The strap is changed using a spring bar tool to release the metal lugs that secure the strap to the case lugs. Gently press the tool to compress the internal spring, remove the spring bar, then insert the new strap aligning it perfectly. For the 123.58.35.20.63.001 model, we recommend having the operation performed by an expert to avoid scratches.
