Strap for Day-Date 36 Yellow Gold Diamonds / President Diamonds / Meteorite

The lug width is 20 millimetres. This is the internal distance between the lugs, soldered to the case. It is a structural dimension and admits no variations: an 18mm strap will create unacceptable lateral play, whilst a 22mm strap will not fit. The 20mm is specific and mandatory for this model.

Alligator with fine grain is the classical solution par excellence. However, Tärnby calf leather represents a modern compromise between tradition and durability. For those desiring more pronounced ageing, vegetable-tanned leather develops patina naturally parallel to yellow gold. On yellow gold, avoid absolute black rubbers; prefer very dark browns or burgundy tones.

The procedure requires specific tools: an original Rolex spring bar remover or a quality watchmaking spring bar remover, and a soft work surface (rubber mat). The process consists of removing the articulation pins by pushing them laterally, extracting the worn strap, inserting the new strap, and securing the pins. Every Rolex for which strap replacement has been performed should subsequently be tested for water resistance. It is advisable to entrust this to an authorised Rolex service centre if inexperienced.

Yes, provided the lug width is exactly 20mm and the constructive quality is certified. A handcrafted aftermarket leather strap in premium materials (alligator, shell cordovan, calf) can elevate the daily wearing experience of the Rolex. It is essential to select craftsmen who understand watchmaking tolerances and who avoid adhesive at critical attachment points, instead privileging correct stitching with quality waxed thread.

A quality watchmaking leather strap (alligator, Tärnby calf, shell cordovan) has an average lifespan of between 4 and 8 years when worn daily, depending on use and ambient humidity. Alligator tends towards the upper limit. Exotic leather is subject to gradual wear: the inner edge develops creasing from repeated flexion, the exterior loses lustre. To regard this as defectiveness is incorrect: it is natural ageing. Many collectors prefer to rotate multiple straps to extend the life of each one.
