Museum Collection 516.53.37.20.09.023— lug 19mm

The lug width of the 516.53.37.20.09.023 measures exactly 19mm between the lugs. This measurement is crucial for compatibility: always verify the distance between the strap attachment points before purchase. A 19mm lug width ensures harmonious proportions with the 37mm case diameter.

Alligator represents the natural choice: its fine grain creates an elegant texture that does not compete with gold, developing a deep patina over time. Vegetable-tanned calf is a sophisticated alternative, while shell cordovan should be avoided because its natural brilliance can overshadow the warm and understated tone of yellow gold.

The strap is secured using removable spring bars. Use a spring bar tool to push the bar laterally, allowing the old strap to slide away from the lugs. Insert the new strap by aligning the hole with the lug and release the bar: it should snap firmly into place. A straightforward operation, but if you are not accustomed to doing this regularly, Casati Milano can perform it at your first order.

Yes, provided the lug width is exactly 19mm. Any strap with this width—leather, NATO, rubber—is technically compatible. However, for a yellow gold Museum Collection timepiece, we recommend noble materials such as alligator or calf: the aesthetic pairing enhances the piece and your investment.

A quality alligator strap with vegetable tanning and careful finishing resists 4-7 years of daily wear. Deterioration depends on exposure to sweat, water, and frequency of wear. Casati Milano offers an 18-month warranty and can perform restorations or replacements. We recommend rotating multiple straps to extend the life of each one.
