Need help identifying a Rolex movement

Hi all,

   I have came across a movement that I'm having a bit of trouble identifying. Markings on it are Rolex. It came in a Rolex case model 4127 which my research indicates to be a Rolex Athlete model. Not very familiar with that particular version of Rolex. I have found that the movement used in that model was normally the 710 caliber but when I compare a picture of that movement to the one I have I see some difference. First off there are extra holes in the balance cock where it looks like a swan neck went? The stud holder has a cover to keep the stud in place instead of the normal screw that I see on other examples of the 710. It almost looks like the movement should be something like a Rolex 630 or 645 missing the automatic wind mechanism. The movement did fit perfectly in the case. The watch had a Rolex oyster perpetual dial however the feet had been removed and dial was glued to movement.

    The watch has a broken balance staff and the pivot is stuck in the upper jewel. I have tried getting it out with rodico but that hasn't worked. I reattached the balance cock for the pictures. Watch also has a slightly bent hairspring so that the outer coil will hit on the center wheel. Anyway before I can source parts I need to be sure of exactly what movement I have found. Any help would be surely appreciated.

Thanks,

Charles K

Its a caliber 630 center seconds without shock resist, a caliber 645 would have shock resist, as you have already worked out its a auto movement with the automatic mechanism removed the whole watch sounds like a bit of a franken.

The way to remove the broken pivot end is to strip down the balance bridge/cap jewel parts. I have tried other methods but this is the only method I have managed to a successful conclusion. I also hope you have the auto parts otherwise it is just going to be a project only watch Parts are as scarce as dragon poo..

Hi,

   Thanks to all the replies. I did see the movement on ebay and have made an offer, we'll see what happens there. I can source a balance staff and jewel from Jules Borel. (Problem with the Jules Borel staff is there are several different staffs for different size hairspring collets). They do have a balance complete though. I had already stripped down the balance cock jewel assembly trying to get the broken pivot out, didn't work. Put it back together just for the picture. Maybe I'll try again while waiting on other parts. My son-in-law picked up the watch for $80.00 so it is a good project. There is a local person who might have parts as well.

   Thanks,

Charles K

Personally I think you would be throwing good money after bad with that watch you have a movement from a bubble back Rolex  a case that should have a manual wind movement in it and a totally unrelated dial so parts from three seperate watches, if you buy the movement from Ebay it wont go into the case you have if you intend to reinstate the auto mechanism it will be too deep to fit. You could get a good return for your son-in-law's $80.00 bucks by selling it for parts and put the money to an all original watch.

The case you have must be worth at least $300.00 to someone and the movement broken down into parts should net more than the $80.00 spent.

Just my two penneth

      Oiling Dubois Depraz chrono module pivots (Omega Speedmaster Reduced)

      By Simeon · Posted

      I have been recently servicing an Omega 3220A chronograph movement which uses a Dubois Depraz 2000 chrono module.  This has been quite a time consuming project, not necessarily difficult but with lots of steps.  Working on the chrono module is like working on the love child of a hugely complex keyless works and a Timex pin pallet movement. I do have access to a couple of Omega tech sheets and a couple of relevant Youtube videos (including Mark Lovick's Breitling series) so I feel confident that I have all of the required information. The 'tractor' movement (effectively an ETA 2892) had no issues with obtaining 300 degree amplitude dial up / dial down and maybe a spread of 7 seconds across all of the positions.  I serviced the chrono module and when reinstalling it, this brought the amplitude down to about 260 degress with the chrono stopped and 200 with it running.  The Omega specification states that the chrono running should see the amplitude drop by no more than 40 degrees (from, I am guessing, the assembled amplitude i.e. chrono stopped rather than just the bare tractor movement). Obviously this isn't good enough. I am going to have to redo the chrono module again.  Where I suspect I have a problem is inconsistent / over oiling of pivots.  For some reason the Omega technical guide states to apply oil to the bottom pivot of each wheel and then place in the jeweled base plate.  In practice, I managed to smear oil on the horizontal base of the wheel which would be smeared over the outside face of the jewel.  This also wouldn't be helped by dragging the wheel around trying to get the lower pivots to engage in the the jewel.  When I watch Mark service a similar Breitling chrono with DD module, he also oils the bottom pivots and installs the wheels (obviously doing a better job than me!).  My question is, why can't I install the wheels dry and the oil the jewel on the other side of the base plate in the conventional way? The top pivots are oiled through the jewels in the conventional way, so why would the lower pivots be any different? Looking at the those jewels (picture below an example from a different movement) it looks like there isn't an oil well in the outside surface of the jewel around the pivot, so perhaps I would be better applying a drop of oil directly to the jewel hole before installing the wheel?  Perhaps the jewels have different arrangement to conventional jewels because the outside face is installed against the dial side of the tractor movement and we don't want to risk oil migrating from the module to the movement. There are also a couple of friction springs that may have an impact on amplitude, I will recheck their pre-load but these should be OK.  Is there anything else I should look at as a source of friction in the DD module?

      I found a Trupoise in a flea market box of tools (🇬🇧car boot). I preferred the ‘8’ style tool until the moment I broke my new Omega rivet. The trupoise holds the arms firmly and I’ve become quite efficient… …and I just resorted to bending a balance cock. I needed a tiny bit less shake and it seemed the least risky of the other options. I held it between a stump and a fat stake while I bent the jewel end with my fingers. Honestly I don’t know how anyone would know by visual inspection.

      It was about 4 years ago, one was 30, another 35 and 2 others came in joblots that I was after something else. 3 have ruby jewels and one has ceramic bearings.The most I've seen one sell for is £330.  In the uk i still see them sell occasionally for around £70.  I'm not convinced that the Trupoise has low enough friction on the pivots to be as good as a traditional tripod poising tool with unworn ruby jaws.
