Short answer
A copy Rolex Sky-Dweller 326939 is a replica of the yellow gold annual calendar GMT that Rolex launched in 2012. The genuine watch has a 42 mm case, caliber 9001, a Ring Command bezel with three positions, a Saros annual calendar, and a 24-hour reference disc at the center of the dial. A good copy matches the case size, dial layout, date magnifier, and bezel action. A weak copy misses the bezel function, prints soft text, and shows thin plating in direct sun.
Specs to match
- Case: 42 mm yellow gold, about 13.8 mm thick
- Movement: caliber 9001, automatic winding, 72-hour power reserve
- Functions: annual calendar, GMT, 24-hour disc
- Bezel: Ring Command with three positions
- Strap: alligator leather with a gold folding clasp
- Crystal: sapphire, 2.5x Cyclops over the date at 3 o'clock
Reference 326939 is the yellow gold model on a leather strap. Reference 326938 is the same watch on a gold bracelet. Sellers mix these two numbers, so confirm the strap and the clasp before you buy.
What a strong copy gets right
Case geometry comes first. The Sky-Dweller is a wide, flat watch, and the lugs sit close to the wrist. Copies with a 40 mm case or a 15 mm profile look wrong next to photos of the real 326939.

Dial work comes second. The month apertures sit around the outer edge of the dial, with the current month shown in red. A good copy cuts these windows clean, aligns them with the markers, and keeps the print weight on the Rolex name and the Oyster Perpetual line.
The 24-hour disc sits at the center, read against a fixed triangle at 12 o'clock. On cheap copies the disc sticks, the numerals blur under a loupe, and the triangle sits off center.
Gold color and weight come third. The real case is solid 18k yellow gold, so the strap version lands near 150 g. A plated copy weighs less, and the color drifts toward brass under indoor light.
How to inspect a copy before you pay
- Ask for caliper photos of the case width, thickness, and lug width.
- Request a short video of the bezel turning through all three Ring Command positions.
- Get macro shots of the date window, the month apertures, and the 24-hour disc.
- Compare those photos against press images of the 326939 from 2012 and 2013.
- Ask which movement sits inside and whether the month indicator jumps with the date.
- Check the clasp stamping and the strap stitching under a light.
- Weigh the watch if you can, or ask for a scale photo.
- Pay with a method that offers buyer protection and a return window.
Movement notes
Caliber 9001 is an in-house Rolex movement with an annual calendar module and a bezel that controls the setting mode. No replica uses a real 9001. Most copies run on a modified Asian or Swiss automatic with a GMT module and a month wheel that may or may not jump on its own. Ask the seller to confirm which functions work. Some copies show the month, but you set it with a pusher or a crown position, not with the bezel.
Price bands
- Low tier, $80 to $200: plated case, printed dial, dead month windows.
- Mid tier, $250 to $500: better case shape, working GMT, month windows that track the date.
- Top tier, $600 to $1,200: closest case profile, sapphire crystal, decorated movement, sharper dial print.
Common buying mistakes
- Judging the watch from a single studio photo with heavy retouching.
- Skipping the thickness check, then finding the watch sits high on the wrist.
- Reading Swiss movement as genuine Rolex movement.
- Paying a top-tier price for a mid-tier case and dial.
- Ignoring the strap and clasp, which are the parts you touch and see each day.
