The test means really nothing, I performed the wiggle..lol..and it does wiggle...the good part is that the movement is 3186 on my new M serial 16710 pictured below...and soon to be sold for 4100...ONLY..(am I going to regret this sale..?).
As far as the story about...
Rolex put the new movements into the "old" (16710) to test the movement prior to putting it in the new case.. ...I do not think that Rolex S.A. would sell a watch as a test mule in order to make sure that another (116710) works perfect .....somehow through the years I found that you are never sure 100% with this company about numbers, calibers, cases, design etc.
