Short answer

Rolex does not make a reference 116710LNR. The catalog holds the 116710LN, a GMT-Master II with a black ceramic bezel and a green 24-hour hand, and the 116710BLNR, the same watch with a blue and black bezel. Listings spelled 116710LNR point to one of those two. Most of them are the 116710LN.

The genuine 116710LN arrived in 2007 and left the Rolex catalog in 2019. Specs: 40 mm Oystersteel case, 12.5 mm thick, 20 mm lug width, sapphire crystal, black Cerachrom bezel with 24-hour numerals, caliber 3186, 100 m water resistance, Oyster bracelet with an Oysterlock clasp.

What sellers ship under this number

Three price tiers cover the market.

  • Low tier, $70 to $130. 316L steel case, mineral glass, painted bezel insert, DG3804B or a low-grade 2836 clone. Case thickness runs to 13.5 mm.
  • Mid tier, $180 to $320. 316L or 904L steel, sapphire crystal, ceramic insert with etched numerals, A2836-2 with a GMT module. Solid links and a stamped clasp.
  • High tier, $400 to $650. 904L steel, SA3186 or SH3186 with an independent hour hand, ceramic insert, AR-coated sapphire, machined Oysterlock-style clasp.

Checks that separate the tiers

  1. Hand stack. The GMT hand on a genuine 3186 sits below the hour hand. Many low-tier builds place it above.
  2. Hour hand function. On a real 3186 the hour hand jumps in one-hour steps and the minute hand stays put. A 2836 with a GMT wheel cannot do this.
  3. Bezel action. The genuine bezel turns both ways in 24 clicks. A 60-click ring or a stiff ring is wrong.
  4. Cyclops. Genuine magnification is 2.5x on the sapphire. Mineral-glass builds show a smaller date or a glued lens.
  5. Case thickness. Genuine is 12.5 mm. Anything past 13 mm changes how a 20 mm strap sits.

Movement names you will see

A2836-2: 25 jewels, 28,800 vph, 40 hours of reserve, GMT hand tied to the hour hand. SA3186 and SH3186: clones of the Rolex 3186, 31 jewels, 28,800 vph, about 48 hours of reserve, independent hour hand. Price tracks the movement. A 3186 clone adds $150 to $250 to a build.

Parts and service

Sellers stock 116710LN cases, bezel inserts, dials, and hands. A ceramic insert costs $30 to $60. A 3186 clone costs $180 to $260. Repair access is thin. Watchmakers in the US often refuse replica work, so buyers swap parts at home.

Legal note
