Short answer
A GMT-Master II 116719BLSO copy has to be judged against the real reference, not against studio photos from a seller. The genuine 116719BLSO is a 40 mm white gold GMT-Master II with a blue sunburst dial, a blue and red Cerachrom bezel insert, and Rolex calibre 3186. A strong copy matches four things: case profile, bezel color split, dial texture, and bracelet finish. A weak copy fails on at least one of them, and that failure shows at arm's length.

What the original reference uses
The 116719BLSO ran from 2014 to 2018, when the white gold Pepsi line moved to the 126719BLRO. The case is 18k white gold at 40 mm, with a polished finish and a slightly warm gray tone rather than the bright silver of stainless steel. The dial is a deep blue with a sunray brush that shifts tone as the wrist turns. The bezel insert is two piece ceramic, half blue and half red, joined at 6 and 18 on the dial. The bracelet is an Oyster with polished center links and a folding clasp. Inside sits calibre 3186, a 28,800 vph movement with a 48 hour power reserve and an independent 24 hour hand.

Prerequisites
- Know the reference number and the production years before you compare anything.
- Use daylight or a bright neutral lamp. Warm indoor light hides dial and bezel flaws.
- Have a jeweler's loupe, a caliper, and a soft cloth on hand.
- Ask the seller for the case size, movement name, and bezel material in writing.
Inspection steps
- Measure the case across the widest point with the caliper. It should read 40 mm, with the crown guards adding width on the right side.
- Check the crown guard shape. On a good copy the guards taper into the case and sit level with the mid case.
- Tilt the dial toward a window. A correct blue dial shows a sunray burst that runs from the center outward and darkens at the edges.
- Look at the printed text on the dial. The coronet, the line under it, and the GMT-Master II name should sit centered and sharp at loupe magnification.
- Study the bezel at the 6 and 18 positions. The red and blue halves should meet in a clean vertical seam, with no bleed or gray haze.
- Turn the bezel by hand. It should move in 24 clicks, bi-directional, with modest resistance and no wobble.
- Inspect the lume. Markers and hands should glow an even blue-green and fade at the same rate.
- Weigh the watch in your hand. White gold reads heavier than steel, and a copy with a steel case feels light for the size.
- Examine the bracelet and clasp under the loupe. Center links should be polished, outer links brushed, and the clasp stamp deep and even.
- Set the 24 hour hand through a full rotation and confirm it jumps in one hour steps without dragging the minute hand.
- Lay the watch on a timegrapher or compare it to a known good quartz watch over 24 hours. Expect roughly minus ten to plus fifteen seconds a day.
Common flaws
- Bezel red that leans orange under daylight.
- Dial blue that reads flat purple with no sunray grain.
- Date font that is too bold or sits off center in the window.
- Cyclops magnification below 2.5x.
- SEL gaps where the end links meet the case lugs.
Movement expectations
Most 116719BLSO copies run an Asian automatic GMT movement, often a modified 2836 or a 3186 clone. Both can keep time, but the 3186 clone is the one worth paying for because the hand stack, the jump hour function, and the winding feel sit closer to the original. Ask which movement is fitted, then test the hour jump in front of the seller before money changes hands.
