FAQ

Q1: Is this a genuine Rolex OEM part?
A: This is a genuine, brand-new replacement rotor designed specifically for Rolex calibers 3130, 3135, 3155, 3186, and 3187. Please confirm whether this is a genuine Rolex part or an aftermarket replacement before purchasing. The part number coverage of five calibers suggests it may be a generic replacement part designed to fit multiple Rolex movement variants.

Q2: Which Rolex watches use these calibers?
A: These five calibers are used in classic Rolex models: Caliber 3130 powers the Datejust 36mm; Caliber 3135 powers the Submariner Date, Datejust 41mm; Caliber 3155 powers the Submariner Date, Sea-Dweller; Caliber 3186 powers the Submariner GMT II; Caliber 3187 powers the Explorer II.

Q3: What does the rotor oscillating weight do?
A: The rotor oscillating weight is the semicircular metal component that spins freely inside the case as you move your wrist. Its bidirectional rotation winds the mainspring through a series of gears. Without a functioning rotor, the watch cannot self-wind and must be manually wound.
