Strap for Day-Date 36 Yellow Gold Diamonds / President Diamond / Paved Roman

The lug width of the Day-Date 36 reference 118348-0076 is precisely 20 millimetres. This is the net distance between the two spring bars that secure the strap to the case lugs. It is an exact specification that must be respected: any aftermarket strap must have exactly this width to fit correctly without gaps or tension anomalies.

Alligator leather remains the primary choice for authentic formal elegance. Full-grain calf is recommended for those seeking a more pronounced texture and superior durability. Shell cordovan offers a visibly ageing patina over time, creating an emotional bond with the yellow gold. For versatile use, a double-layer NATO strap maintains practicality without aesthetic compromise. Milano Straps' <a href="https://milanostraps.it/collections/cinturini-orologi-per-misura-ansa-20mm">20mm strap collection</a> offers all these options.

The procedure requires a spring bar tool. Position the tool beneath the spring bar on the underside of the case, pushing the bar inward until one end disengages from the lug tube. Fully extract the spring bar and remove the old strap. Insert the new strap, aligning the holes with the lug tubes, then reinsert the spring bar. Verify that both ends are securely anchored. If you lack experience, consult a certified watchmaker.

Yes, provided it has a 20-millimetre lug width and is manufactured with thickness between 1.2mm and 1.8mm. Milano Straps offers handcrafted straps specifically dimensioned for this case. Always verify technical specifications, and if you choose the Casati Milano service, you can personally follow every manufacturing phase in the atelier with WhatsApp consultation.

A high-quality alligator or full-grain calf strap offers a lifespan of 5–8 years of moderate daily wear. Shell cordovan tends to last longer (8–10 years) due to fibre characteristics, but requires an initial adaptation period. The dominant factor is exposure to water and perspiration: avoid immersing the strap and dry it if wet. Milano Straps guarantees 18 months against manufacturing defects and can execute partial replacements of lugs and rivets.
