Short answer
No replica Rolex 6239 Paul Newman uses the movement of the real watch. The genuine 6239 runs a Valjoux 72 base, which Rolex marked as caliber 722. Replicas use one of four movements: a Seagull ST19 hand-wound chronograph, an Asian 7750 automatic, a Seiko VK64 meca-quartz, or a plain quartz with a printed dial.

What the real 6239 movement does
Rolex built the ref 6239 from about 1963 to 1969. The chronograph is hand-wound. It has a column wheel, a horizontal clutch, 17 jewels, and a beat rate of 18,000 vibrations per hour. There is no date. The case is 37mm wide, with 19mm lugs and pump pushers.
Rolex 6239 Paul Newman Replica Review: Which Build Gets It Right
Seagull ST19
This is the closest match in layout and the common pick in mid-range replicas. The design comes from Venus 175 tooling that Tianjin Seagull bought from Switzerland in 1961. It is hand-wound, has a column wheel, and runs at 21,600 vibrations per hour. Jewel counts on vendor sheets run from 19 to 22 by variant. The pushers feel crisp. The beat rate is higher than the real watch, so the balance moves faster.
Asian 7750 and 7753
An Asian 7750 is a clone of the ETA 7750: automatic, 25 jewels, 28,800 vibrations per hour, cam switching. The rotor adds thickness. A 6239 case built for a 7750 measures about 14mm to 15mm thick, against about 13mm for the real watch. Builders strip the day and date parts or hide the date under the dial. Subdial spacing differs from the ST19, so dial printing is not shared between the two.
Quartz and meca-quartz
The Seiko VK64 and VK63 are quartz movements with a mechanical chronograph module. The chrono seconds hand sweeps in small steps when the stopwatch runs. Cheap quartz builds use a battery movement and subdials that do not move at all.
How to tell which movement is inside
- Watch the chronograph seconds hand. It jumps 5 times per second at 18,000 vph, 6 times at 21,600 vph, and 8 times at 28,800 vph.
- Listen for a rotor. A hand-wound ST19 has none.
- Measure case thickness with calipers. 13mm points to hand-wound, 14mm to 15mm points to a 7750.
- Compare subdial spacing to a photo of a real 6239.
What cannot be confirmed
Most sellers do not name the movement in listings. The 6239 caseback is solid, so a photo of the back proves nothing. The movement can be checked after the case is opened, or not at all. No replica 6239 case takes a real Valjoux 72 without machining.
Price bands
Quartz builds sit under $100. ST19 builds run from about $200 to $500. 7750 builds run from about $300 to $800. A franken build with a real Valjoux 72 and a replica dial crosses $10,000 in parts alone. These are market ranges, not fixed prices.
