The lug width is exactly 20mm. This measurement is crucial for the compatibility of any aftermarket strap. To verify it, use a digital caliper positioned between the inner sides of the two lugs on the case.

For the two-tone gold and steel version, we recommend dark brown or black alligator, which reflects the sophistication of the case without competing with it. Valid alternatives: Italian calf leather with vegetable tanning (ages naturally), or shell cordovan for absolute durability. The choice depends on your usage style and color preferences.

Remove the watch from any current strap using a spring bar tool to push the retention pins. Insert the new strap by aligning the holes with the lugs, then snap the pins into place until they engage. If uncertain, the Casati Milano atelier offers the strap change service by appointment in Milan.

Yes, provided the strap is specifically calibrated for a 20mm lug width. Milano Straps are cut and stitched to exact width, with tailored passants that fit perfectly to the case proportions without lateral play.

Durability depends on material and usage. Alligator and shell cordovan with vegetable tanning, with regular maintenance and seasonal rotation, exceed 5-7 years. More delicate leather requires quarterly care (conditioning). Milano Straps warranty: 18 months on all artisanal straps, with worn passant replacement included.
