Museum Collection 516.53.37.20.09.010— lug 19mm

The lug width is exactly 19mm, a rare dimension that reflects the constructive proportions of the 37mm case. Verify the measurement by positioning a caliper between the metal lugs of the case to avoid errors when purchasing a strap.

Alligator in honey or cognac tones represents the choice most coherent with the historical aesthetics of the model. If you prefer everyday simplicity, vegetable-tanned calf leather ages magnificently over time, developing a patina that harmonizes with the yellow gold case.

Extract the lateral pins of the case using a dedicated tool (spring bar tool): position it on the two small grooves present on each side of the lug and push gently downward to free the pin. Remove the previous strap and insert the new one, then reinsert the pins. The procedure takes less than three minutes if you have the appropriate tool.

Yes, completely compatible. It is essential to verify that the strap is specifically designed for a 19mm lug width, as this dimension is not standard in mid-range collections. Milano Straps offers a dedicated selection of 19mm straps made in premium leather and structured rubber.

A premium leather strap such as alligator or shell cordovan normally lasts between 4 and 8 years in daily use, provided minimal maintenance (avoid prolonged moisture, store away from direct light). Vegetable tanning ages gracefully, creating patina; chrome tanning is more resistant but patinas less. Casati Milano offers an 18-month warranty on all custom straps.
