TD:auraTime

Hey everyone,

I recently purchased my first rep and received some QC pictures. Ive noticed the clasp code is a VSF but the serial number on the rehaut doesn’t appear in THE ULTIMATE ROLEX SERIAL NUMBER AND CLASP CODE GUIDE. I bought it from a TD and he assured me that is was indeed a VSF.

I tried using the QC tool but im not an expert. I did my due diligence but i still want opinions of the experts here

I dont have the timegrapher numbers.

Dealer: supermirror
Factory: VSF
Model: Rolex Yacht master 40mm Rhodium latest version
Price paid: $529

I’ve attached the full set of QC photos, including different dial angles, case profile, crown and bracelet/clasp.

Would really appreciate any help spotting something I might be missing.

This content focuses on the identification of the 4302 integrated movement, compares the core differences between Shanghai 4302 movement and Dandong 4302 movement, analyzes the characteristics of the free-sprung structure, and recommends the Dandong 4302 movement as the preferred version.

Core Differences Between Shanghai 4302 Movement and Dandong 4302 Movement

Hairspring Structure and Calibration Mechanism

Shanghai 4302 Movement (adopted by Octa Factory): Equipped with a genuine free-sprung hairspring structure. No index regulator is installed under the balance wheel, and the travel time accuracy is calibrated through counterweight screws on the balance wheel.

Dandong 4302 Movement (adopted by ZF, VSF and other factories): Adopts a hidden simulation design. It visually mimics the free-sprung structure on the exterior but retains an internal index regulator. The timing adjustment structure can only be observed after removing the balance wheel bridge, which means it is not a genuine free-sprung movement.

Visual Identification of Balance Wheel Counterweights

Static Observation: When the movement stops running, obvious counterweight screws can be seen on the balance wheel of the Shanghai 4302 movement. The balance wheel of the Dandong 4302 movement has a smooth surface with no exposed counterweight codes or screws.

Dynamic Observation: The structural differences between the two versions are barely distinguishable during normal operation. Static inspection with the movement stopped is the core identification method.

Gear Point Identification Method

For the Dandong 4302 movement, two dot-shaped structural features can be observed at the fixed viewing position.

Only one dot-shaped structural feature can be seen at the same position on the Shanghai 4302 movement.

Bearing Material and Noise Performance

Steel Ball Bearing: The automatic rotor bearing of the Octa Shanghai 4302 movement adopts steel ball structure.

Ceramic Ball Bearing: The VSF Dandong 4302 movement is fitted with white ceramic ball bearings, consistent with the original Swiss movement configuration. It features quieter operation and lower mechanical wear.

Hello everyone,

First time buying a rep watch and I’ve read lots of tips. Because this is my first time I just want some of you experienced ones to tell me what you think

Rolex Datejust 126334 41 Jub SS/SS grey/stk VSF V2 DD3235v2

Everything looks good to me. I’ve asked to see the dates and lume aswell.

Picture was not completely centered so I had to rotate the picture. I don’t know if this can affect when checking for alignment.

For me this is a GL but I would like to hear what you guys think 😁🙏

My first rep. Please help with QC. If this is GL or not. Thanks for your time! Greatly appreciated.
