Strap for Datejust 36 Stainless Steel / Everose / Fluted / Silver - Palm / Jubilee

The lug width of the Rolex Datejust 36 126231-0031 is 20 mm. This measurement corresponds to the distance between the inner edges of the lugs (the metal U-shaped elements where the strap attaches to the case). It is crucial to verify this measurement before ordering a replacement strap: a strap with a different lug width (18 mm, 22 mm) will not fit correctly and risks damage. Compatibility is absolute and unambiguous.

For the two-tone rose gold and stainless steel Datejust 36 (126231-0031), alligator leather remains the formal solution of choice due to its fine grain and the patina it develops over time, enhancing the rose gold. Alternatively, quality leather with vegetable tanning offers environmental consciousness while maintaining high tactile quality. Absolute black (alligator or dyed leather) enhances the luminosity of rose gold through contrast; chocolate brown creates warm chromatic continuity; dark bordeaux dialogues elegantly with the steel component.

To change the strap on the Datejust 36, you must first remove the bracelet or original strap by extracting the pins that connect the lugs to the case. This requires a specific tool: a pin pusher or dedicated precision instrument. Once the pins are removed, the lugs loosen and the original strap can be withdrawn. The new strap (compatible with 20 mm lug width) is inserted through the lugs in the same direction and the pins are reintroduced and secured. It is recommended to entrust this operation to an experienced watchmaker to avoid scratches on the case, or contact Casati Milano for artisanal mounting service.

Yes, any aftermarket strap with a 20 mm lug width is compatible with the Datejust 36 126231-0031, provided that the lugs are dimensioned correctly and the material (alligator, leather, rubber, NATO) is chosen according to aesthetic preference. Casati Milano artisanal straps in 20 mm are specifically designed and constructed for this reference. Compatibility is guaranteed by the fact that the case's lug width is fixed and invariable: exactly 20 mm.

The lifespan of a leather strap depends on intensity of use, climatic conditions, and leather quality. An artisanal strap in quality alligator or leather with vegetable tanning can last from 5 to 10 years in moderate daily use. Exposure to perspiration, humidity, and sunlight accelerates wear. Natural leather develops patina and micro-cracks that attest to its ageing: this evolution is a desired characteristic by many collectors. Casati Milano straps include an 18-month warranty against manufacturing defects and can be regenerated through re-dyeing or leather restoration.
