Strap for Day-Date 36 Everose Gold / Diamond / MOP-Diamond / President

The Rolex Day-Date 36 with reference 128345RBR-0028 features a lug width of 20 millimetres. This measurement is standard across all Day-Date 36 variants, regardless of case material or dial configuration, and represents the primary compatibility specification for any aftermarket strap. Always verify lug width before purchasing a replacement strap, as an incorrect measurement will render the product incompatible with your timepiece.

For a rose gold presidential-category timepiece, straps in alligator crocodile or vegetable-tanned calf leather with satin finishing represent the pinnacle of aesthetic coherence. Alligator delivers elegant, subtle texture and exceptional durability, whilst calf offers superior workability for custom tapers and lug-to-lug adjustment. Casati Milano specialises in bespoke leather selection within its Milan atelier, allowing clients to personally choose hides and monitor each production phase via direct communication channels.

Strap replacement requires a dedicated tool: a spring bar remover. Secure your watch in a stable holder, locate the lugs (the two protruding lateral extensions of the case), gently apply inward pressure with the remover tool to release the spring bar, and slide out the existing strap. Align the new strap with the lugs, ensuring proper seating, and re-engage the spring bar with deliberate pressure until audibly secured. If unfamiliar with this procedure, entrust the operation to an accredited service centre to prevent case damage.

Yes, absolutely. Premium aftermarket leather straps are entirely compatible provided they are manufactured to the 20mm lug width specification. Artisanal manufacturers such as Casati Milano produce straps in alligator, shell cordovan and vegetable-tanned calf, all customisable with bespoke spring bars and personalised deployante clasps. A high-quality replacement strap enhances rather than diminishes your timepiece's versatility and does not compromise its collector value.

Leather strap longevity depends on material quality, wearing frequency and environmental conditions. A high-grade alligator strap, subjected to routine maintenance (thorough drying after water exposure, storage in a dry environment), will typically endure 4–6 years under daily wear. Vegetable-tanned leathers develop a natural patina over time, improving aesthetic character. Casati Milano provides an 18-month warranty against manufacturing defects and supplies comprehensive care instructions with each strap delivered.
