justlounging Posted February 2, 2012 Report Share Posted February 2, 2012 As indicated in the topic title, I would like to find out what is the average PR that you guys are achieving from your 7734 movements. Also, how many winds do you have to perform on the crown/stem before the movement is fully wound? I am currently getting about 36hrs and around 30-35 winds on my 7734.. Will servicing the movement help push a much longer PR? Would like to hear from the experts here.. Thanks in advance all! Quote Link to comment Share on other sites More sharing options...
alligoat Posted February 2, 2012 Report Share Posted February 2, 2012 You're talking about as 40 year old movement, so the FIRST thing you need to do is get it serviced. My educated guess is your PR should be 40-45+ hours and it should take 40-50 turns to fully wind it. Although the watch may be keeping somewhat accurate time it undoubtably suffers from low amplitude, a sign of being in need of servicing. In the CONUS, that runs $200-300 from a decent watchmaker. If you're in the third world it will be less! Quote Link to comment Share on other sites More sharing options...

RWG Technical Posted February 2, 2012 Report Share Posted February 2, 2012 Every 7734 I have serviced has been neglected for many years...they just don't seem to get the regular attention the movement deserves, probably due to the value of the watches the movements are installed in...

seafoam Posted February 2, 2012 Report Share Posted February 2, 2012 Mine has a recent COA and pr is over 40 hours for sure. About 50 plus turns when movement is stopped. Quote Link to comment Share on other sites More sharing options...

gplracer Posted February 2, 2012 Report Share Posted February 2, 2012 What is fully wound? Can it be over wound? The Zigg did a great job on mine! Quote Link to comment Share on other sites More sharing options...
redwatch Posted February 2, 2012 Report Share Posted February 2, 2012 My recently Ziggy serviced 7734 gets approx 44 hours on a full wind. A full wind is when you wind it until you cannot turn the crown anymore. It comes to a stop (I'm guessing with some sort of clutch mechanism) Quote Link to comment Share on other sites More sharing options...
RWG Technical Posted February 2, 2012 Report Share Posted February 2, 2012 Same rule applies to all handwind models: Rule 1, wind the watch fully as soon as you get up, before putting it on your writs and before you wear it for the day Rule 2, a full wind is NOT a few turns, or a dozen turns, or 20 turns, a FULL WIND is when you wind the watch and continue to wind the watch until you can't turn the crown any more that is a FULL WIND Rule 3, if you ignore Rule 2, you will have poor timekeeping and there is risk of the balance escapment being damaged due to low amplitude More problems with handwind watches are caused by owners who are too scared to wind their watch fully... The mainspring is secured to the side of the mainspring barrel, when you reach full wind the spring is held secure and tight against the barrel. You would have to be super human to accidentally break a mainspring from fully winding it. Quote Link to comment Share on other sites More sharing options...

lhooq Posted February 3, 2012 Report Share Posted February 3, 2012 M, I'm still watching those three 7734s that I fully wound yesterday afternoon. I'll be keeping tabs of when they stop, for my curiosity as much as yours, at this point. Quote Link to comment Share on other sites More sharing options...

woof* Posted February 3, 2012 Report Share Posted February 3, 2012 Winding all the way is true for non chronos? Like my eta 2846 and aj21? Quote Link to comment Share on other sites More sharing options...
Jkay Posted February 3, 2012 Report Share Posted February 3, 2012 Winding all the way is true for non chronos? Like my eta 2846 and aj21? For automatic movements, you should wind it enough to start it running steadily then wear it. The mainspring of an automatic is not permanently attached to the barrel wall and is designed to slip when it's over-wound so the crown will never come to a full stop if you wind it to "full power" ... I suppose the question has a different answer depending on what you do all day. Do you sit at a desk, pushing papers around? You will probably never move enough to keep your watch wound so YES wind it manually. 40 turns for a fully depleted watch. If you spend a reasonable part the day on your feet walking around then the watch will wind itself. I once counted the spins it took for the power reserve meter on my Ulysse Nardin to move from Empty to Full power .. 1000 spins of the rotor!

justlounging Posted February 4, 2012 Author Report Share Posted February 4, 2012 Jus a quick update: mine has been running for 41hrs so far..hopefully can squeeze in another couple hours.. Quote Link to comment Share on other sites More sharing options...
woof* Posted February 4, 2012 Report Share Posted February 4, 2012 Thanks for the reply Jkay, I have never wound any of my automatics to the end or even felt slipping. I wind them up 40 or so and wear them a few days till I switch to another. I don't have any auto chronos yet.. Quote Link to comment Share on other sites More sharing options...
justlounging Posted February 4, 2012 Author Report Share Posted February 4, 2012 Ok..movement finally stopped..running at a very respectable 45.5hrs..i'm very happy at the end result.. Quote Link to comment Share on other sites More sharing options...
lhooq Posted February 4, 2012 Report Share Posted February 4, 2012 After two days, I have a winner. All three were originally set at 12:00, so add 36 hours to the indicated times: The unsigned 7734 in my DW 7032 stopped at 45h07m. My recently-bought Wakmann gets 46h33m. The unmounted, unsigned movement I got from siesta181 last year runs for an impressive 48h48m! Quote Link to comment Share on other sites More sharing options...
