Royal Collection LCAP.M07A.C110A— lug 20mm

The lug width of the LCAP.M07A.C110A is precisely 20mm. This measurement is critical for strap compatibility and is determined by the distance between the two lug holes at the case extremities. It does not tolerate significant tolerance variations.

For a timepiece of this aesthetic calibre, alligator leather with a fine grain is the natural choice: its regular appearance dialogues perfectly with the precise geometry of the rose gold case. Alternatively, vegetable-tanned calf offers authenticity and dramatic patina development over time. For versatility, a light grey NATO allows the case to take centre stage.

Strap replacement requires a spring bar tool to extract the elastic pins from the lugs. Insert the tool's fork between lug and pin, apply gentle pressure to compress the spring, and simultaneously extract the pin. Operate delicately to avoid scratching the rose gold case. Insertion of the new strap follows the inverse procedure.

Any strap with a 20mm lug width is compatible. It is crucial to verify that the strap thickness at the passage does not exceed 3.5-4mm to avoid fatigue of the elastic pins or micro-scratches to the case. Milano Straps offerings for the 20mm size are tested on references of this class.

A quality leather strap, worn daily on a single lug, has an average lifespan of 4-6 years before replacement is advisable. This duration depends on climate, humidity, frequency of wear, and leather care. Vegetable-tanned calf develops natural creases that extend its aesthetic appeal beyond the functional terminus; alligator typically maintains itself longer before showing signs of fatigue.
