Rolex reference 16710R?
Hello,
I'm about to purchase a GMT 16710, from a know watch dealer in my area. The warranty card reads 16710R. Anybody ever seen this reference number before? Also, it is a 16710(R) M serial, normal II dial (no stick dial). What are the chances this has a 3186 movement? It is not that important to me but I would just like to know. I'm also unable to go and test the watch with the wiggle test because the shop is quite far away from me. Thanks! Tom |

Yes - IIRC the R just referred to the Rouge bezel color(Coke) on the SS GMT. Should be the 3185.

i thought that all M serials and the later Z serials had the 3186 movement.

If it is a M serial, the chances of 3186 are 100%

the only way to find out is to ask them to open up the case back and show you.

I wouldn't bother opening the watch up just to check its the 3186,just enjoy the watch whatever movement it has in it.

I'm sorry, I missed the M reference in your post. Agree with Luke about the relative merits - in fact another discussion on the 3185 vs. 3186 has some interesting points: http://www.rolexforums.com/showthread.php?t=38309
BTW, what price is he asking?

From my webpage at https://www.minus4plus6.com/paracromblu16710.php#crown
The Crown Method Another method for discerning a 3185 with the 3186 movement is through the the Crown Rotation Method. This method is another way to discern the type of movement without having to remove the caseback. Because the calendar and hour-hand setting mechanism was redesigned in the 3186 movement, the number of turns of the crown to turn the 12 hour hand is different on a 3186 than it is on a 3185. To perform this test, unscrew the crown such that the crown is in the hand setting position. With the crown face-up, count how many hours the hour-hand travels with one full revolution of the winding crown. 3185: one complete crown revolution makes the hour hand jumps 6 timezones/hours 3186: one complete crown revolution equals 8-9 timezones/hours This tip was provided to Minus4Plus6.com by Ed who discovered this method on a French watch forum. ~ Sheldon
