Short answer
A Rolex 6623 vintage style clone is a current-production watch built to look like a 1950s Datejust. Expect a 36 mm steel case, 20 mm lugs, a domed or pie-pan dial, an acrylic crystal, and an automatic movement. The clone copies the look. It does not copy the original movement, the original tolerances, or the original value.

What reference 6623 is
Reference 6623 sits in the 1950s Datejust family, the line Rolex launched in 1945 and moved to a 36 mm Oyster case in the years after. Published reference tables disagree on the production window for 6623 and on which bezel and dial combinations shipped with it. Treat any single date range as unconfirmed. Check the caseback stamp, the serial range, and the movement number before you accept a claim about a specific watch.

Parts that decide the look
- Case: 36 mm across, 20 mm between the lugs, about 12 mm thick with the crystal fitted.
- Crystal: acrylic, domed, with a wide bevel at the edge. Sapphire changes the profile.
- Bezel: fluted or smooth. Originals are machined steel. Many clones use plating.
- Dial: pie-pan or domed, applied markers, printed minute track. Check marker height and lume plots.
- Hands: dauphine or alpha shape, length matched to the minute track.
Movement options in a clone
Three builds show up in the market:
- Asian copy of a 28,800 vph (4 Hz) automatic. Sweep is smooth. Parts are easy to source.
- Swiss ETA or Sellita base at 28,800 vph. Higher cost, easier service, better rate stability.
- 21,600 vph (3 Hz) automatic. Lower cost, coarser sweep, closer in sound to a 1950s rotor movement.
Power reserve lands near 38 to 42 hours on all three. Ask for the movement name and a photo of the rotor before you pay.

Checks on arrival
- Measure case width and lug width with calipers.
- Time the rate over 24 hours in three positions.
- Inspect the bezel for plating wear at the edges.
- Confirm crown threads and crystal fit.
- Look at the dial print under 10x magnification.
What the clone does not do
It does not hold collector value. It does not carry a Rolex movement or Rolex service records. Resale sits at a fraction of the purchase price. Water resistance on a vintage-style case with an acrylic crystal is limited. Do not swim with it unless the maker states a rating and a test result.
