Datejust 36 116234-0115— lug 20mm

The Rolex Datejust 36 116234-0115 is equipped with 20-millimetre lug width. This measurement is standard for Datejust 36 models and determines the compatibility of all aftermarket straps. Always verify the lug width with a calliper before purchasing a replacement strap to avoid improper fitment or gaps between the lug and the strap.

Alligator leather in vegetable tanning represents the most refined choice for a Datejust 36 in white gold and stainless steel, owing to its fine grain and the patina that develops naturally over time. A black anthracite or cognac brown alligator enhances the luminosity of the white gold. Alternatively, shell cordovan in dark burgundy offers superior abrasion resistance and beauty that increases with wear. Satin-finished calf remains a classical solution for those preferring softness and versatility.

The strap is changed by removing the spring bar pins that connect the strap to the case lugs. Use a dedicated spring bar removal tool to push the internal mechanism and extract the pin. Insert the new strap by aligning the lugs with the attachment points, ensuring the pins click securely into position. Never force: the mechanical click must be distinct and secure. If inexperienced, consult a certified watchmaker.

Yes, provided the strap is manufactured to the correct lug width (20mm) and with controlled material quality. Aftermarket straps in alligator, calf, and shell cordovan from specialised artisans do not damage the case and offer aesthetic alternatives that Rolex itself does not fully cover. Avoid inferior-quality straps with defective stitching or synthetic materials that degrade rapidly.

A high-quality leather strap (alligator, calf, shell cordovan) has an average lifespan of 3–5 years with moderate daily wear, or 5–7 years with occasional use. Longevity depends on sun exposure, humidity, perspiration, and frequency of wear. Vegetable-tanned alligator develops a protective patina over time that extends its life. To prolong durability, keep the strap dry, avoid prolonged water contact, and occasionally apply specialised leather balm.
