Museum Collection 516.53.37.20.09.018— lug 19mm

The lug width of the 516.53.37.20.09.018 is 19 mm. This measurement is determined by the distance between the two internal case lugs and is essential for selecting compatible straps. It is important to measure correctly by positioning the caliper between the lugs, without including the thickness of the strap attachments, to ensure precise fit.

For the 516.53.37.20.09.018 in yellow gold, alligator represents the most coherent choice: the fine and regular grain texture enhances the warmth of gold without appearing pretentious. Refined alternatives include vegetable-tanned calf and shell cordovan in dark brown tones (cognac, teak or deep burgundy). The choice depends on intended use and personal preference between vintage or contemporary aesthetics.

To change the strap, you need to use a specific tool to remove the spring bars that connect the strap to the case. Position the watch with the case facing downward, locate the small hole next to each spring bar and insert a flat tool to compress the internal spring. Once the old spring bar is removed, insert the new strap and verify proper positioning before releasing pressure. It is recommended to perform this operation carefully to avoid scratching the gold case.

Any strap made with a 19 mm lug width is compatible with the 516.53.37.20.09.018. On milanostraps.it a complete collection of artisanal 19 mm straps is available, customizable in leather (alligator, calf, shell cordovan), color, initials and stitching type. Atelier Casati Milano also offers the possibility to create fully bespoke straps according to personal preferences.

The lifespan of a leather strap depends on the material and use. Alligator and shell cordovan, thanks to fiber strength and intrinsic resistance, maintain excellent condition for 3-5 years of daily wear. Calf, being more delicate, requires greater care and may need replacement after 2-3 years in case of intensive wear. Vegetable tanning promotes natural aging and patina development, visually extending the aesthetic life of the strap. Casati Milano guarantees straps for 18 months against manufacturing defects, but actual longevity depends on maintenance and lifestyle.
