Read the reference before the listing
The Rolex 16750 GMT-Master ran from 1981 to 1988. It replaced the 1675. The steel case measures 40 mm across. Lug width is 20 mm. The bezel turns both ways on a 24-hour scale. The 16750 has a quickset date. The 1675 does not. That one detail tells you which watch a replica copies.
Ask the seller for the exact reference the copy follows. A generic "GMT-Master" listing can hide a 1675 case, a 16710 dial, and a 16750 bezel insert in one watch.
Which era does the copy match?
Early 16750 watches used a plexiglass crystal and a matte dial with painted hour markers. Later watches moved to a sapphire crystal and a glossy dial with metal surrounds on the markers. Caliber 3075 sits inside both, 27 jewels, 28,800 beats per hour, 100 m water resistance.

A sapphire crystal on a matte dial copy mixes two periods. So does a ceramic bezel insert on a 1980s reference. Original inserts are anodized aluminum.
Parameters to confirm before payment
- Case: 40 mm diameter, 20 mm lugs, crown guards shaped like the 1675 profile.
- Case height: about 12.5 mm.
- Dial: matte with painted markers for early copies, glossy with metal surrounds for late copies. Tritium dials read "Swiss - T <25". Later dials read "Swiss Made".
- Crystal: acrylic or sapphire, matched to the dial era. Ask how far the crystal sits above the bezel.
- Hands: hour, minute, seconds, plus a red 24-hour hand. Ask for a close photo of the center pinion and the hand stack.
- Bezel insert: red and blue (Pepsi), black and red (Coke), or black. Ask for the material.
- Bracelet: 20 mm Oyster. Folded links and stamped clasps fit earlier watches.
- Engravings: reference number between the lugs at 12 o'clock, serial at 6 o'clock. Request a photo of both.
Movement: the part sellers hide
Three movements show up in replica 16750 watches: the Asian 2836 clone with a GMT module, the DG3804, and a Swiss ETA 2836-2. The genuine 3075 runs at 28,800 beats per hour. The DG3804 runs at 21,600. Beat rate is a fast check, but you need a movement photo or a video with sound to count it.
GMT hand action differs by movement. On some clones the red hand tracks the hour hand and cannot be set on its own. On others it sets from the crown. Ask how the 24-hour hand sets, then ask for a video of the crown at each position.
Date setting differs too. A genuine 16750 changes the date from the crown. Cheap clones with a slow-set date force you to cycle past midnight 30 times.
Pitfalls that cost money
- Studio photos with heavy color grading. Ask for a phone photo in daylight, no filter.
- Wrong era parts: sapphire crystal with a matte dial, ceramic insert on a 1980s case.
- Two-tone copies of the 16753. Ask for plating thickness in microns. Plating under 5 microns wears through at the clasp and crown.
- Lume that glows green and bright. Tritium on an original 16750 no longer glows.
- No movement photo, no case back photo, no serial photo.
- Payment by wire, gift card, or crypto with no refund path.
- Import risk. US law bans counterfeit goods. Customs and Border Protection seizes shipments and destroys them. 18 U.S.C. 2320 covers trafficking. Your money is gone and the carrier owes you nothing.
Price and terms
Replica GMT-Master 16750 listings sit between $120 and $500. Movement, case finish, and dial quality drive the spread. Shipping runs from free to about $40. Confirm the total before you pay. Get the return window and the return address in writing. Ask for the movement beat rate, the crystal type, and the dial text. A seller who cannot answer those three questions is a seller to skip.
