ryaku Posted June 1, 2006 Report Posted June 1, 2006 It surely sounds like a stupid question and probabily it is. I mean: when i HAVE to wind manually my watch? I know we'd better do that the first time we use the watch. Do you wind manually ever time your watch stops running when you don't wear it? waiting for tips
Pugwash Posted June 1, 2006 Report Posted June 1, 2006 Do you wind manually ever time your watch stops running when you don't wear it? Yes, especially when I'm photographing them and I want the time to be right. Winding automatic watches isn't bad for them or anything.
ryaku Posted June 1, 2006 Author Report Posted June 1, 2006 Yes, especially when I'm photographing them and I want the time to be right. Winding automatic watches isn't bad for them or anything. Perfect ...but is there some risk of overwinding? Thanks Pug
retep Posted June 1, 2006 Report Posted June 1, 2006 Perfect ...but is there some risk of overwinding? Thanks Pug According to The Zigmeister you cannot overwind an automatic watch. Venus movements you wind until you feel a little resistance.
Chronus Posted June 1, 2006 Report Posted June 1, 2006 Venus movements are manual winds. Manual winds will give resistance when fully wound. Automatic movements have protection to stop over-winding, otherwise just wearing it could cause it to overwind. Therefore you cannot overwind an automatic watch.
ryaku Posted June 1, 2006 Author Report Posted June 1, 2006 Thanks lads, i learn something everyday here
Chronus Posted June 1, 2006 Report Posted June 1, 2006 True, I'd forgotten about that, and I own one! I have a Breitling for Bentley rep which is the same... this was pre-RWG when I got it off eBay. Never worn it. I asked the seller once I received it why I couldnt wind it, they said it will work if you wear it. Peeeeeeeeeeeeeeeeeeeeeeeeeee...
swdivad Posted June 1, 2006 Report Posted June 1, 2006 My watchmaker told me that winding an auto watch isn't bad if done in moderation... Apparently, the winding mechanism is somewhat like a clutch and eventually manual winding can wear components... He said something about the 'barrell', but this was a long time ago, so can't remember the details.
infinitime Posted June 1, 2006 Report Posted June 1, 2006 You cannot overwind an automatic, as it has a clutch which allows for slippage once the movement is fully wound. Basically, an automatic movement is a regular hand-wind mechanical movement, with the addition of a rotor for "auto-winding" and a clutch to prevent over-winding. In most cases, hand winding an automatic would not damage it....However, if you continue to wind after the mainspring is already fully compressed, it will put unnecessary wear and tear on the slippage clutch...which may result in premature wear...but this would require ALOT of overwinding.
Chronus Posted June 1, 2006 Report Posted June 1, 2006 I would guess 10-30 winds to get it going if you are going to wear it should be fine. Wearing it will wind it unless you stay in 1 position for the whole week!
Highflyingclive Posted June 1, 2006 Report Posted June 1, 2006 The Zigmeister advises that you should not wind basic Chnese autos - just give them a gentle shake and strap them on. He said that winding ETAs is OK - but why would you want to?

He said that winding ETAs is OK - but why would you want to? Because I have far too many watches and can't afford a winder (more watches - feed me FEED ME).
Pugwash Posted June 1, 2006 Report Posted June 1, 2006 Because I have far too many watches and can't afford a winder (more watches - feed me FEED ME). Do what I do. Set 'em when you wear them Otherwise, let them run down.
infinitime Posted June 1, 2006 Report Posted June 1, 2006 actually, 4-watch winders are readily available for about $50 on the Bay, including shipping.
Chronus Posted June 1, 2006 Report Posted June 1, 2006 actually, 4-watch winders are readily available for about $50 on the Bay, including shipping. that could be put towards a relume or AR coat
Highflyingclive Posted June 1, 2006 Report Posted June 1, 2006 actually, 4-watch winders are readily available for about $50 on the Bay, including shipping. Fine. I would need at least a dozen. So, I will continue to choose the watch that I will wear today... set it... and enjoy it. Damn sight cheaper that buying a dozen winders :-)
Chronus Posted June 2, 2006 Report Posted June 2, 2006 Agreed... not to mention the space those winders take up... and I have absolutely no where to put them... not even on top of the stacks of 1000s of records (they reach the ceiling in some cases!).
fitmic Posted June 2, 2006 Report Posted June 2, 2006 actually, 4-watch winders are readily available for about $50 on the Bay, including shipping. Yeah, and then it's $95 shipping outsida USA.
eddhead Posted June 2, 2006 Report Posted June 2, 2006 Yeah, and then it's $95 shipping outsida USA. There is a real good write up by The Zigmeister in the knowledge section on automatics and maintenance. It is comprehensive and detailed and really helped me understand how different automatic movements work, which are best, and how to care for them. Basically, for most automatics, you cannot overwind them because of the clutch. In fact, The Zigmeister recommends winding new ones up to 100 'winds' before wearing them.

Basically, for most automatics, you cannot overwind them because of the clutch. In fact, The Zigmeister recommends winding new ones up to 100 'winds' before wearing them. Actually the clutch CAN wear out, but it will take literally thousands of "over-winding" to do it.
Finepics Posted June 3, 2006 Report Posted June 3, 2006 Lets get this absolutely straight - a handwound watch obviously need to be wound about every 40 hours or so or it stops. An automatic, such as a 7750, also needs to be wound up before it is first worn - it is designed to be wound up - the instructions on a gen will tell you to do this - how else do you wind the mainspring enough to give a 40-50 hour reserve - the action of wearing them simply keeps the spring topped up once it has been wound initially. There is not enough movt of the rotor to wind a watch fully just by wearing it. It is extremely unlikely that you will ever wear out components by winding the watch up during a reasonable lifetime - the balance cap jewels are far more likely to wear out long before then. My PAM 28 power reserve has to be wound if run down as just wearing it is not enough to even move the reserve indicator - but once wound the auto mechanism keeps it on max while I am wearing it. The only rule to observe is with the 2892-3 movts - these need to be wound a little more slowly than say a 7750 due to the more sensitive clutch assembly.....
eddhead Posted June 4, 2006 Report Posted June 4, 2006 Actually the clutch CAN wear out, but it will take literally thousands of "over-winding" to do it. I stand corrected. Thanks.
