Mowa o moim zegarku Dziwnie tak otwierać zegarek bez potrzeby, skoro nigdy nie był otwierany do tej pory. Książeczka jest od mechanizmu 3186. Mechanizm 3186 pojawil się w Explorerze II od serii M razem z napisami "Rolex*Rolex*Rolex wygrawerowanymi na wewnętrznym ringu. "Wiggle test robiłem" zaraz po kupnie, wskazówka gmt nie ma luzów, kiedy ruszam wskazówką godzinową w dwie strony. Zegarek był kupiony u profesjonalnego sprzedawcy, który sprzedaje również na Allegro. Prośba o inspekcję za granicą, bez mojego udziału, to trochę ryzykowne - dla mnie oczywiście. Ponizej fragmenty ze strony: http://luxurytyme.com/en/rolex-related-articles/the-explorer-ii-16570-3186-the-last-of-the-five-digit-sport-rolex-models/ (....) Now an interesting thing happened with the five-digit 16570 in the years just prior to its discontinuation. At the same time (2008) that Rolex began shipping the last of the five-digit GMT Master II models (I call them the 16710-3186 models) which received the newer Rolex 3186 movement (M serial production), 16570 Explorer II models (both white and black dial versions) began showing up in dealer cases with an engraved rehaut (the “RolexRolexRolex engraving) and also equipped with the 3186 movement. Click on the photo to enlarge and look closely at the rehaut (inner bezel) and you can see the “RolexRolexRolx” engraving. (....) DISTINGUISHING A 16570 FROM A 16570-3186 Because of their rarity relative to the 16570 production run, collectors will no doubt be seeking out the 16570-3186 models for many years to come. But how does one confirm that any given 16570 is in fact a 16570-3186? The best way to confirm with absolute certainty is to remove the case back on any 16570 you suspect may be one of the last production examples with the 3186 movement and visually inspect the movement (photo above). Beyond that, the leading indicators are: -An M serial production 16570 or later -The engraved rehaut. -The “wiggle” test (see below). (...) The “Wiggle” Test It isn’t always practical to remove the case back on a watch you’re considering purchasing to inspect the movement, so collectors and enthusiasts have devised another way to determine the presence of a 3186 movement in a 16570 or a 16710 – the “wiggle” test. If you spin the jump hour hand forward or backward on a Rolex GMT Master II or Explorer II which has the 3185 movement, the GMT hand has a tendency to oscillate back and forth or “wiggle.” This particular anomaly was corrected in the 3186 movement, so performing this same operation on a 16570-3186 or 16710-3186 should not yield any movement of the GMT hand.
