Strap for Datejust 36 Stainless Steel Fluted / Oyster / Blue

The lug width of the Rolex Datejust 36 116234-0128 is 20 mm. This width is specific to the model and is determined by the geometry of the 36 mm case. It is important to measure the lug width accurately using a digital calliper positioned perpendicularly between the two case lugs, at the narrowest point, to ensure complete strap compatibility.

For the Datejust 36 in white gold and stainless steel, natural alligator straps in black or deep brown maintain aesthetic coherence, whilst cognac alligator or aged caramel calf leather add character. Vegetable-tanned calf at 2.0–2.2 mm thickness is ideal for those who appreciate a patina developing over time. FKM rubber suits those preferring contemporary materials and dimensional stability. Consult Casati Milano for personalised guidance at the atelier.

Strap replacement requires a spring bar tool to extract the elastic pins anchoring the strap to the lugs. Position the watch on a stable surface, access the lateral attachment of each lug, and gently push the pin towards the case centre. Fully remove it, extract the old strap, and insert the new one, ensuring the pins engage correctly in the lug slots. If uncertain, entrust the work to a certified watchmaker or contact Casati Milano.

Any strap with a 20 mm lug width is compatible. Milanostraps offers a wide selection of artisanal straps in alligator, vegetable-tanned calf, shell cordovan and technical rubber, all in 20 mm width. It is essential to verify that strap thickness (standard 2.0–2.4 mm) is not excessive, to avoid friction at the lugs. Browse the online catalogue or contact Casati Milano for a considered choice.

Durability depends on material, frequency of use and maintenance. A quality alligator strap with vegetable tanning typically lasts 5–8 years of moderate daily wear. Shell cordovan is more resilient but requires rapid drying after moisture exposure. Vegetable-tanned calf, ageing naturally, may remain functionally sound for 7–10 years, though aesthetics evolve. FKM rubber offers dimensional stability of 10+ years. Casati Milano provides an 18-month guarantee on manufacturing defects and guidance on periodic maintenance.
