A replica Rolex Daytona 6263 is a copy of the vintage manual-wind chronograph that Rolex produced from the early 1970s to the late 1980s. The best replicas match the original's 37 mm case, screw-down pushers, and acrylic bezel. Use the steps below to judge a replica's accuracy and function.
Prerequisites
- 10x jeweler's loupe
- Digital calipers
- Small flat-head screwdriver
- Soft cloth
Steps
- Measure the case diameter with calipers. The original 6263 measures 37 mm across, excluding the crown.
- Check the pushers. The 6263 has screw-down pushers. Turn each pusher counterclockwise to unscrew it, then press to start, stop, and reset the chronograph.
- Inspect the bezel. A correct 6263 replica has a black acrylic bezel with a tachymeter scale. The scale should be printed with crisp edges, not etched into metal.
- Examine the dial. The subdials at 3, 6, and 9 o'clock should be recessed. The text "ROLEX" and "OYSTER PERPETUAL" should align with the original font weight.
- Look at the crystal. The 6263 uses a domed acrylic crystal, not sapphire. Check for a slight bulge above the bezel.
- Verify the crown. The crown should be 6 mm and signed with the Rolex coronet. It should screw down onto the tube with no gap.
- Test the chronograph. Start the chronograph, let it run for 60 seconds, then stop and reset. The seconds hand should return to 12 o'clock without hesitation.
- Open the case back. Use the screwdriver to remove the case back. The movement should be a manual-wind chronograph. A Valjoux 72 or 727 clone is common. Check for a smooth winding action.
- Check the engravings. Between the lugs at 12 o'clock, look for "6263" and a serial number. The font should be crisp and shallow.
- Compare the weight. A stainless steel replica should weigh about 60 to 70 grams with the bracelet. A lightweight feel suggests cheap materials.
What to Avoid
- Pushers that do not screw down
- Sapphire crystal instead of acrylic
- Printed subdials that sit flat
- Case diameter over 38 mm
