Strap for Day-Date 40 Platinum / Silver Tuxedo

The Rolex Day-Date 40 228206-0034 features a lug width of 20mm. This measurement is taken as the distance between the two lateral attachment points on the case where the strap connects. Accurate verification of this dimension is essential before ordering a replacement strap to ensure compatibility.

The optimal material depends on intended use and aesthetic preference. For formal elegance, African alligator with traditional tanning pairs naturally with the nobility of platinum and develops patina over time. For low-maintenance options, vegetable-tanned calf offers saturated colour and durability. For dynamic contexts, vulcanised rubber is the most versatile and resilient solution. At Casati Milano, you can personally select the material in the atelier by appointment.

Strap replacement requires a dedicated spring bar tool. Remove the watch from your wrist or position it to access the lug sides. Insert the small curved stem of the tool into the release hole beneath the spring bar, apply gentle pressure to disengage the bar, then remove the old strap. Align the new strap's passant hole with the bar and press until it clicks into place. If inexperienced, entrust this task to a certified professional.

Yes, provided the lug width is precisely 20mm and the passant is designed for Rolex presidential cases. Casati Milano straps are handcrafted with certified precision and guaranteed for 18 months. Unlike generic online straps, these are constructed using premium materials (alligator, calf, shell cordovan) and artisanal finishing techniques that honour the watch's original aesthetics.

Longevity depends on material, usage and maintenance. A quality African alligator strap, with regular care (drying after humidity exposure, annual conditioning with natural creams), typically lasts 4-6 years. Vegetable-tanned calf, more absorbent, requires closer attention but evolves aesthetically. Vulcanised rubber, if properly stored away from direct sunlight and excessive heat, maintains functional integrity for 5-8 years. Casati Milano straps include an 18-month warranty against manufacturing defects.
