Q1: Is this a genuine Rolex OEM part?
A: No — this is a generic aftermarket crown tube compatible with Rolex Datejust 116233 and 116234. It is not manufactured by Rolex. The term “Rolex” refers to the compatibility with Rolex watch models, not the brand origin. The part number B24-5330-0 is provided for identification purposes.
Q2: What Rolex models does this tube fit?
A: This crown tube is designed for Rolex Datejust references 116233 and 116234. The 116233 is the two-tone (steel and gold) Datejust, while the 116234 is the stainless steel Datejust, both with 36mm case size. Always verify your Rolex reference number (engraved on case back or between lugs at 12 o’clock) before purchase.
Q3: What does M4.0 × 1.5 + M2.5 × 1.5 mean?
A: These are dual-thread specifications: M4.0 × 1.5 mm is the outer thread that screws into the watch case, and M2.5 × 1.5 mm is the inner thread where the crown stem passes through. The “M” prefix indicates metric threads. This standard Datejust tube size is smaller than larger Rolex models like the Explorer II 216570.
