iceshark099 Posted April 4, 2012 Report Share Posted April 4, 2012 I am in the market for an IWC 3714 and I know about the movement problems but I read somewhere on this forum that a service would keep the watch running as long as it was done right when you get the watch and again every 12-18 months and if you hack it when you are not using it, is that true and if so who would be able to do that in the US? At some point I want to swap out the movement but I don't have the money for that right now. So in the mean time I want to wear it but keep it from dying at the same time. Thanks for the help guys!

dmacnz Posted April 5, 2012 Report Share Posted April 5, 2012 These a lot of mixed reports. Rolexman seems to be the guy to get in touch with. I think Domi also services them, but is some controversy if you have a deep read. Im sure either would probably keep you ticking till you could upgrade. Worst case could get a replacement rep movement! Quote Link to comment Share on other sites More sharing options...

Worst case could get a replacement rep movement! How easy is it to get a replacement movement? I couldn't find one on the interwebz. I suppose a properly serviced movement is better off than a new one anyway Sent from my GT-I9100 using Tapatalk Quote Link to comment Share on other sites More sharing options...
FxrAndy Posted April 5, 2012 Report Share Posted April 5, 2012 The problem with this movement is the design, not the servicing, it is like a 4 wheeled car with only 3 wheel bearings, Quote Link to comment Share on other sites More sharing options...
iceshark099 Posted April 5, 2012 Author Report Share Posted April 5, 2012 The problem with this movement is the design, not the servicing, it is like a 4 wheeled car with only 3 wheel bearings, So then a service wouldn't guarantee that the watch would keep working for awhile? Do you know how much a new movement would cost for this watch? Quote Link to comment Share on other sites More sharing options...
gimme Posted April 5, 2012 Report Share Posted April 5, 2012 I think service is not the right word. What people do to make the A7750 more reliable is do a graphite treatment. Do a search on that. New movement would be around $100. Getting the movement out of the case is a pain in the a$$. Quote Link to comment Share on other sites More sharing options...
nwolf1716 Posted April 6, 2012 Report Share Posted April 6, 2012 So basically I think we all want to know is if it is safe to buy it or are we basically wasting money on it? I know I want one but I think I would want to get it serviced first, not graphite treatment but a service as someone else mentioned in another post about this watch, that the newer versions wouldn't benefit from graphite treatment, I could be misinformed though.

I just made a post on this topic http://www.rwg.cc/topic/145132-portuguese-seconds-at-six-some-facts/ I have not seen any credible data that answers your question. I have placed a 3714 on a winder after it was fully serviced and it stopped working after 3 months. Of course, this is just a random data point.

wtchgk Posted April 6, 2012 Report Share Posted April 6, 2012 wtchgk: An improved model 3714 or the original version without the new jewels Everything I posted refers to the new and improved version with the additional jewels. Please see the details in my thread from earlier today. Quote Link to comment Share on other sites More sharing options...
Jkay Posted April 6, 2012 Report Share Posted April 6, 2012 Did a postmortem of the watch reveal the cause of death? Was it the additional gears of the power-train OR a problem with the 7750 internals? Quote Link to comment Share on other sites More sharing options...
wtchgk Posted April 6, 2012 Report Share Posted April 6, 2012 Did a postmortem of the watch reveal the cause of death? Was it the additional gears of the power-train OR a problem with the 7750 internals? The metal to metal friction of gear 3 and gear 4 of the nine to six transfer gears stopped the watch. When these gears were removed the watch continued to work. I have since replaced the jewels of gears 2, 3, and 4 to eliminate all metal to metal friction. I am testing how much of an improvement this is. The main problems, however, remain, namely too much overall friction because of the size of the jewels and axis and because these gears can't hold normal watch lubricants.

I'm glad to see you have make this a pet project. Perhaps you can crack this problem wide open. Thanks and good luck to you. Quote Link to comment Share on other sites More sharing options...
iceshark099 Posted April 6, 2012 Author Report Share Posted April 6, 2012 So what you recommend, buy the watch get it serviced and hack it when not in use and repeat that every year or so. OR just hack it when not in use and not get it serviced. OR is there another better option to consider? Thanks for all the help everyone!

Guest Posted April 12, 2012 Report Share Posted April 12, 2012 here's a noober question: how do i wind this watch? never had an automatic before Quote Link to comment Share on other sites More sharing options...
gimme Posted April 12, 2012 Report Share Posted April 12, 2012 Just wear it and it will wind. Or 'shake it' with your hand as if you were dealing a deck of cards. Quote Link to comment Share on other sites More sharing options...

Jkay Posted April 12, 2012 Report Share Posted April 12, 2012 The 7750 movement Swiss or Asian suffer from a weak winding gear. If you wind it by turning the crown clockwise, do it slowly and gently or you can strip off the gear teeth. If you do not move around much every day because you are a desk jockey, you will need to invest in a watch winder or your watch will simply stop due to your inactivity. A 7750 movement needs 800 swings of your wrist per day to be fully wound. So you see, if you work in an office that's not going to happen. Place the watch in the palm of your hand, face up, with the strap wrapped around your hand. Swirl your hand like you are swirling a drink in a glass. Only 800 of those and you're wound! That's why people buy watch winders. One last thing. 7750 only winds in one direction. If you swirl it the wrong way you're just wasting your time.
