Strap for Datejust 36 Stainless Steel Diamond / Jubilee / Pink Floral

The lug width of the Rolex Datejust 36 116244-0004 is 20 millimetres. This measurement is specific to the 36 mm case diameter and is critical for strap compatibility. Measurement must be taken between the inner extremities of the lugs, perpendicular to the case plane. An 18 mm strap will leave play, while a 22 mm strap will not fit. Only 20 millimetres ensures correct passage and optimal spring bar tension.

For a bicolour Datejust in white gold and stainless steel, American alligator is the most elegant choice: its fine grain and natural patina create aesthetic continuity with the case's nobility. Alternatively, vegetable-tanned calf develops a deep and sophisticated patina over time. For informal occasions, a dark navy cotton NATO with white stripes maintains authority without compromising practicality. Vulcanised rubber is ideal for humid climates or technical daily use.

Changing the Datejust 36 strap requires a specific tool (spring bar tool) and a steady hand. Locate the lateral hole of the lug spring with the tool tip, apply gentle and consistent pressure until the spring compresses, then extract the metal end of the spring from the hole. Repeat for both sides. The new strap must be inserted by perfectly aligning its extremities inside the lugs, then release the spring by pressing it into the opposite hole. Verify that the passant embraces both lug poles without play. If unsure, consult a professional watchmaker.

Yes, the Datejust 36 116244-0004 accepts 20 millimetre aftermarket straps in any material, provided they are constructed to standard. Alligator, calf, shell cordovan, NATO and rubber straps are compatible. The quality of the aftermarket strap determines durability and final aesthetics. Full-grain leather straps with double stitching and refined finishes maintain the Rolex's prestige; low-quality budget straps betray the investment in the case. On milanostraps.it you will find artisanal straps for the 20mm lug width, crafted with noble materials and guaranteed for 18 months.

A high-quality leather strap (alligator, shell cordovan, premium calf) lasts between 3 and 5 years of daily use, depending on exposure to moisture, perspiration and direct sunlight. The natural patina that develops enhances the strap's character within the first 12–18 months, after which the leather begins to show visible signs of aging. Materials such as traditionally-tanned alligator tend to preserve themselves better over time than calf. A strap with a precious metal deployant lasts longer than one with a steel buckle, thanks to reduced tension on the stitching. Regular maintenance (gentle cleaning and conditioning every 6–8 months) significantly extends strap lifespan.
