Strap for Master Ultra Thin Moon Pink Gold / Eggshell / Alligator

The Q1362511 features a lug width of 21 mm. This dimension is specific to this model and derives from the proportional design of the 39 mm Master Ultra Thin. To verify it correctly, measure internally between the two contact points of the lugs: the result should be exactly 21 mm.

Given the aesthetic purity of the watch and the noble case material (18k pink gold), we recommend alligator or superior calf leather. Alligator leather crafted with vegetable tanning offers natural texture and patina that evolves over time, emphasising the introspective character of the watch. Alternatively, shell cordovan delivers unmatched chromatic depth and softness, ideal for those seeking elegant minimalism.

The Master Ultra Thin features standard spring bars. Use a dedicated strap changing tool or a blunt ballpoint pen. Place the watch on a soft surface, gently push the spring bar inward, slide the old strap out, then insert the new one. Verify that the bars are fully seated in their housings. Alternatively, Atelier Casati Milano offers professional strap changing services by appointment in Milan, ensuring expert handling.

Absolutely. A bespoke leather strap from a reputable artisan transforms the sensory experience of the watch entirely. The 21 mm lug width ensures compatibility with custom straps from specialists such as Casati Milano, or with the 21 mm straps available in the milanostraps.it online catalogue. Your choice of leather—alligator, calf, shell cordovan, vegetable tanning—influences both durability and aesthetic evolution: an artisanal strap typically lasts 3–5 years with proper maintenance, developing a patina that tells your watch's story.

Leather strap longevity depends on construction quality, tanning method, and intensity of use. An artisanal strap crafted in vegetable tanning or alligator can last 3–5 years with daily wear, developing a natural patina that improves over time. Factors such as humidity, direct sunlight, and perspiration accelerate deterioration. To extend strap life, avoid frequent water exposure, occasionally apply cadmium-free leather conditioners, and rotate use between alternative straps. Casati Milano straps include an 18-month warranty against manufacturing defects.
