Strap for Day-Date 36 Yellow Gold Diamonds / Oyster / Champagne

The lug width of the Day-Date 36 reference 118348-0134 is precisely 20 millimetres. This measurement is fixed and defines the geometry of the spring bar holes and the depth of the buckle housing. Any compatible strap must strictly respect this specification to ensure stable and proportionate attachment.

Mississippi alligator represents the classic aesthetic choice for a yellow gold Day-Date 118348-0134, as the vivid grain texture contrasts elegantly with the metal's lustre. Italian vegetable-tanned calf offers minimalist restraint. Shell cordovan provides thin gauge and natural rigidity. For summer contexts, satinised rubber preserves the gold from accidental scratching whilst maintaining formal elegance.

To measure the lug width, position a metal ruler perpendicularly across the two lugs of the case, measuring the distance between the inner edges of the strap attachment points. For the Day-Date 36, this measurement must be exactly 20 millimetres. Precision is critical: even a 1-millimetre variance would generate friction or anchorage play, compromising security and proportional harmony.

Yes, provided it is constructed with a 20mm lug width. Bespoke artisanal straps represent a superior choice compared to factory products: they permit customisation of material (alligator, calf, shell cordovan), colour and buckle type. Casati Milano offers custom straps with an 18-month guarantee on manufacturing defects, with every phase of construction tracked via WhatsApp.

A high-quality alligator strap with proper tanning and stitching maintains functional integrity for 4–6 years of regular wear. Vegetable-tanned calf tends to patina more rapidly, achieving 3–5 years. Shell cordovan, if not exposed to excessive moisture, can last 7–8 years. Longevity depends on frequency of use, exposure to water and perspiration, maintenance (periodic cleaning and conditioning), and construction quality of the stitching and buckle.
