You can spot a fake Rolex Explorer II 16559 by checking five things: the engraved 24-hour bezel, the missing cyclops over the date, the caliber 3085 movement, the dial text spacing, and the caseback reference stamps. One clarification matters here. Rolex never made a reference 16559. The number almost always means the Explorer II 16550, built from 1985 to 1989, or its successor, the 16570, built from 1989 to 2011.
Explorer II 16559 White Dial Fake: A Replica Buyer's Guide
Does a Rolex Explorer II 16559 reference exist?
No. Rolex reference numbers for the Explorer II are 1655, 16550, and 16570. A listing that says 16559 is either a typo for 16550 or a seller repeating a fake reference.

Treat that error as a first warning sign. Ask the seller for a photo of the reference stamp between the lugs and on the caseback. A real 16550 shows the same number in both places.

What should you check first on an Explorer II 16550?
Start with the bezel, the crystal, and the hands. These three areas show the most common replica failures, and you can inspect them without opening the case.
Bezel engraving and font
The 16550 uses a fixed stainless steel bezel with 24-hour numerals engraved and filled in black. Genuine engraving is crisp, evenly deep, and sits inside a slightly brushed surface. Fakes often show shallow cuts, rounded numeral edges, and an uneven fill that bleeds past the engraving lines.
No cyclops over the date
The Explorer II never has a magnifying cyclops on the crystal. The date sits flat under sapphire at 3 o'clock with no bubble. Any 16550 or 16570 wearing a cyclops is wrong, and that error shows up on a large share of replicas.
The 24-hour hand and hand stack
The GMT hand is a bright orange arrow with a white gold border and a slim shaft. Replicas usually miss the color, landing on a red-orange or a flat painted finish instead of the layered genuine look.
Check the hand stack too. On a caliber 3085 the hour, minute, second, and 24-hour hands sit in a specific order. A GMT module bolted onto a cheap base movement often pushes the 24-hour hand too high or too low.
How do you verify the movement?
The 16550 runs the Rolex caliber 3085, a 27-jewel automatic with a rate of 28,800 vibrations per hour and an independently settable 12-hour hand. That independent hour hand is the whole point of the reference, and it is the hardest feature for a replica to copy.
Have a watchmaker put the movement on a timing machine. A rate reading near 21,600 beats per hour points to an ETA 2836 or a similar stand-in, not a Rolex movement. Caseback threads, gasket fit, and rotor engraving also separate genuine Rolex finishing from aftermarket work.
Which dial details separate real from fake?
- Text spacing: "ROLEX" and "OYSTER PERPETUAL" sit tight and level, with the coronet centered above them.
- "EXPLORER II" print: thin, sharp serif lettering with even spacing, never heavy or blurred.
- Tritium signature: early dials read "SWISS - T < 25" at 6 o'clock. Later ones read "SWISS MADE."
- Rail dial variants: the two lines of chronometer text align like rails on a track, which fakes rarely match.
- Lume plots: round, evenly filled, and aging to a warm cream, not a uniform flat yellow.
Dial patina alone proves nothing. Fakes are aged on purpose, so match the dial against the movement and the case stamps.
Case, caseback, and bracelet tells
The 16550 case measures about 40 mm across with a thickness near 12.5 mm and a signed winding crown. Lug finish should be polished on the sides and brushed on top, with sharp lug edges rather than soft, over-polished curves.
The caseback carries a stamped reference and serial, and many early 16550 cases have drilled lug holes. Genuine bracelets are Oyster 78360 units with 501B end links, a signed clasp, and a coronet that meets the clasp surface cleanly.
Quick authentication checklist
- Confirm the reference stamp reads 16550, not 16559.
- Verify no cyclops sits over the date.
- Inspect bezel numeral depth and black fill.
- Time the movement and confirm 28,800 vph with an independent hour hand.
- Compare dial text weight and tritium signature against the production year.
- Check caseback, lug holes, and bracelet end link codes.
If any single check fails, walk away. Reference numbers, movements, and crystal setup cannot be corrected with a service, and each one is expensive to fix.
