Datejust 36 116234-0147— lug 20mm

The lug width of the Rolex Datejust 36 ref. 116234-0147 is 20mm. This dimension is determined by the width of the pins that connect the case to the strap lugs. To verify it correctly, use a digital calliper measuring perpendicularly between the two pins: the value should be between 19.8mm and 20.2mm. Do not confuse this with the case diameter (36mm), which is completely different.

For the Datejust 36 in Rolesor, we recommend alligator in cognac or tobacco tones, which enhance the white gold through tonal continuity. If you prefer versatile leather, Tuscan calf with vegetable tanning adapts to formal and everyday contexts, developing a personal patina over time. For intensive use, shell cordovan combines extreme resistance with natural lustre. The choice depends on intended use and wrist: a 36mm requires careful proportions between strap and case.

Strap replacement requires precision tools: a dedicated pin remover and a stable work surface. Position the watch face down, locate the pin on one side of the case (not near the crown), insert the pin remover from the inside and apply gentle pressure until the pin emerges. Repeat on the other side. Remove the old strap, align the new lugs with the case holes and reinsert the pins with light pressure until they click. If you are not experienced, entrust the task to an authorised service centre.

Yes, provided it is made specifically for 20mm lug width. Quality artisanal straps verify this dimension during design and assembly. Milanostraps offers a collection of 20mm straps compatible with the Datejust 36, made with noble materials (alligator, Tuscan calf, shell cordovan) and manufactured to order. An aftermarket strap does not compromise the watch's value if made to high construction standards; indeed, it expands its aesthetic versatility.

Durability depends on use, maintenance and leather quality. Well-maintained alligator or shell cordovan resists 3–5 years with regular daily use, developing an interesting patina. Tuscan calf with vegetable tanning, being softer, lasts 2–3 years before requiring replacement or refurbishment. Critical factors: avoid prolonged exposure to fresh or chlorinated water, dry quickly if wet, store in a not-excessively-dry environment. Regular maintenance with specific creams extends strap life. Casati Milano offers an 18-month warranty on manufacturing defects for all artisanal straps.
