Trésor 428.18.36.60.02.001— lug 18mm

The lug width of the Trésor 428.18.36.60.02.001 is 18mm. This dimension, measured from the center of one spring bar to the other, requires straps specifically sized for 18mm to ensure proper fitting to the lateral slots of the case.

Alligator in dark brown shades (mahogany or tobacco) represents the most natural choice for the Trésor, thanks to its regular grain that harmonizes beautifully with the case geometry. Alternatively, vegetable-tanned calf leather or heavy cotton NATO straps offer versatility without aesthetic compromise.

The strap is changed through the spring bars that pass through the case slots. Using a dedicated removal tool, press the spring bar to unlock it from one side, extract the strap, then insert the new one ensuring the spring bar locks correctly. If the model features a deployant, verify that the closure mechanism is intact.

Yes. Milanostraps offers a dedicated collection of straps for the 18mm lug width, all compatible with the Trésor. The selection includes options in alligator, calf, shell cordovan and NATO, with customization possibilities in sizes, initials and stitching thread. The Casati Milano atelier also offers bespoke straps by appointment with personal leather selection.

A quality artisan leather strap, such as those in vegetable tanning or shell cordovan, lasts on average 2-5 years with daily wear, developing a natural patina over time. Longevity depends on humidity exposure, frequency of use and maintenance. Casati Milano straps carry an 18-month warranty and can be subject to extraordinary maintenance interventions.
