Day-Date 36 118348-0024— lug 20mm

The Rolex Day-Date 36 118348-0024 features a lug width of 20 millimetres. This measurement indicates the internal distance between the case attachment points. Always verify by measuring from one lug shoulder to the other: precise millimetre accuracy ensures compatibility with aftermarket straps.

For a yellow gold Day-Date 36, we recommend alligator in cognac or light brown tones, which creates a natural chromatic resonance with the gold. Alternatively, vegetable-tanned calfskin in brown or shell cordovan in burgundy offer tactile density and a patina that evolves over time. Avoid overly cold contrasts such as pure black.

Strap replacement is performed by removing the spring bars from the case lugs. Use a dedicated spring bar tool to gently compress the spring mechanism and extract the bar. Insert the new strap by aligning the lug width to the case attachments, then reposition the spring bars ensuring the strap is securely fixed without play.

Yes, any strap with a 20mm lug width is structurally compatible with the Day-Date 36 118348-0024, provided the construction quality and materials are commensurate with the watch's value. Artisanal alligator, calfskin, cordovan or FKM rubber straps guarantee superior structural and aesthetic compatibility versus industrial alternatives.

A premium leather strap—alligator or shell cordovan—typically lasts 5–8 years under normal wearing conditions, accounting for exposure to moisture, light and mechanical stress. Vegetable-tanned leather requires regular maintenance with specialist creams. Casati Milano's warranty covers manufacturing defects for 18 months; thereafter, the natural ageing of the leather reflects the authenticity of the material.
