gioarmani Posted October 28, 2006 Report Share Posted October 28, 2006 I'm of the understanding that inside the red circle (in the pic below) is where the time can be adjusted up to +/- 5 secs a day, per the etched notches in this ladies Datejust 2671 ETA movement. My girl's datejust runs about a minute & 1/2 fast per day, so I did adjust that to the lowest "-" setting on the regulator (I believe that's what that particular part is called), and it's still running almost as fast; even after a lube job. I noticed that by comparison (in the second pic) in the 2836 ETA in my GMT II & Sub, that regulator part sits opposite in the movement (i.e., if you're looking at the movement with the crown facing north, in the ladies, the regulator points down with the + & -, and in the mens, it points up: If you also notice the two parts registered by red arrows--a & b ( I have no idea what they're called, but logic would suggest they also have something to do with beat/time regulation)--both are in view and closer together on the ladies model, where one is farther over & out of view on the mens model. Do the resident experts happen to know what these two parts are called, and what their purpose is, and more specifically how do I correct the excessive speed on the ladies model? Simply move them further apart? Thanks again for your time. Link to comment Share on other sites More sharing options...
gioarmani Posted October 28, 2006 Author Report Share Posted October 28, 2006 I thought somebody would have jumped at this by now. Link to comment Share on other sites More sharing options...
RWG Technical Posted October 28, 2006 Report Share Posted October 28, 2006 ... and it's still running almost as fast; even after a lube job. If you sent the watch out for a "lube Job" and it's running almost as fast as it was before you sent it out, then whoever did the work most likely didn't do anything... After servicing it's normal for the watch to run slower or faster than it was before servicing...and normally a watchmaker would adjust the beat and rate to specifications... Strange that after servicing you still have a fast running watch, and not only that, but it's as fast as it was before it went out...weird... In any event, comparing the 2671 to a 2836 is meaningless, as they are not the same movement... To adjust the rate without a timing machine is a long process, and because you have to move the regulator arm, very risky for damage to the hairspring.. If you look at your first picture, it tells me that there is a problem, because the two levers are so close together, and the watch is still running fast (fast watch is either out in beat or dirty or dry...). To adjust the watch, move LEVER A towards lever B, and this will make it run slower...how much to move I can't tell you, you will have to move it a little bit, and then time it and see how it does... If you end up with the two levers almost touching, then the chances that you had a "lube job" are next to nil, as normally these levers are quite far apart on a correctly serviced and oiled watch...maybe you got a "snow job" instead...

gioarmani Posted October 28, 2006 Author Report Share Posted October 28, 2006 I actually did the oiling myself (which is where I was afraid I might have moved these arms one way or the other when piecing it back together), but I've done an oiling on 2 other ETA's & one Asian model with success. I'll definitely try what you suggest--not sure if it's proper or not but I'm comparing the timing of this watch to 3 of my ETA's which are almost exact to the second, and those to the digital clock on the iMac. If this doesn't seem to do the trick, I'm guessing your next suggestion would be to take to an actual watch-smith? Thanks again. Link to comment Share on other sites More sharing options...
gioarmani Posted October 28, 2006 Author Report Share Posted October 28, 2006 Don't know if it makes any difference but the oil I used was J.D. Windle's watch oil from the UK. Link to comment Share on other sites More sharing options...
david-aussie Posted October 28, 2006 Report Share Posted October 28, 2006 Was the whole movement pulled apart and cleaned before oiling . or did u just put some oil onto the jewels ? Link to comment Share on other sites More sharing options...
gioarmani Posted October 28, 2006 Author Report Share Posted October 28, 2006 The whole movement. Link to comment Share on other sites More sharing options...

My only comment would be that oiling a watch requires that it be totally taken apart, cleaned completely until there is no trace of oil anywhere, and then assembling it and oiling it with not only the correct qualtity, but the correct viscosity oil(s) i.e. it takes 5 types of oils and greases on this particular movement...I am not clear if you took the movement completely apart...if you did, congrats because this is one of the most difficult movements to work on, bar none... Based on the comment that you used one type of oil (I am not familiar with that particular oil) and the watch is running fast, I would say the reason is that it's running fast is due to over-oiling...with too thick an oil... This is an extremely small movement, and requires minute amounts of oil in each pivot...anything more than the amount in between these parantheses (.) especially in the escape and 2nd wheel pivots, and the movement is over-oiled... Running fast with that spacing between the arms, would indicate to me to have it either serviced by a watchsmith, or at least adjusted on a watch timer...

gioarmani Posted October 28, 2006 Author Report Share Posted October 28, 2006 Thanks again RG. It's got to be over oiled then, unless it needs to be demagnetized possibly? Forgive my ignorance, but I'm not sure it's been in contact with anything magnetic--I'm still new to this. It's possible that I could have over-oiled it; it's not a wonderful thought to have sunk all this $ into tools, only to have to still pay another party to fix such a simple problem. I've moved the two (a& arms apart & it's still gained aprox 10-15 secs just in the past hour. Link to comment Share on other sites More sharing options...
gioarmani Posted October 29, 2006 Author Report Share Posted October 29, 2006 Set it at 6:30pm, came back at 1am--already 7 minutes fast...off to the shop tomorrow... Link to comment Share on other sites More sharing options...
RWG Technical Posted October 29, 2006 Report Share Posted October 29, 2006 Ok on the follow on. Unlikely to be magnetized, as modern movements contain Non-Magnetic balance hairsprings...this was an issue in the old days, but not really a problem anymore... Servicing it will take care of the fast running... RG Link to comment Share on other sites More sharing options...
gioarmani Posted October 29, 2006 Author Report Share Posted October 29, 2006 Yeah, unfortunately that seems to be the issue. I got my local smith to disassemble it, ultrasonic clean it, lube it again, and reset the beat for $89--it'll take 1 week so I figured that wasn't too bad.

kingkitesurf Posted October 31, 2006 Report Share Posted October 31, 2006 Man that signature picture drives me crazy... Get another cuz this makes me concentrate on other things than your fast running movement... Link to comment Share on other sites More sharing options...
Graman Posted September 9, 2007 Report Share Posted September 9, 2007 Amen.....I can only concentrate on one thing at a time...I am a bloke!........... VERY interested in seeing how you go...I have exactly the same problem.. Have tried oilling using an insulin syringe...seems to work, having a fine tip.....
