It looks as if the day wheel has popped off the movement. There is nothing but the dial holding the day wheel in place, if there is too much of a gap between the wheel and the dial then the day wheel can pop off... The only fix would be to remove the dial and fix the day wheel. RG

Thank you so much for the feedback and kind words. It was my pleasure being able to help you out. RG

Impossible to know what the problem was/is. Watches don't fix themselves, I think your problem is going to reappear...sorry... RG

Great picture, thanks... The case number of this watch is 178.0514 Crown 42154 Tube 090 ST 1237 RG

I consider a "Tic" to be one move of the hand, and a "Toc" to be one move also... RG

I wish I had better news, but I had to replace all of mine... To make sure I give you the correct part numbers, please post a picture or a link of your watch, the PO automatic and the SMP chrono take different crowns and tubes, I dont' want you ordering the wrong parts. I'll have to look in my reference info to get you the correct parts once I see exactly what you have. RG

Common problem on most of the Omega's lately, PO, SMP Chrono etc... Only fix is to replace the crown, I have replaced them all with genuine crowns to eliminate the problem all together. RG

I am indeed referring to the rep swan necks, most are purely for decoration and dont' work. Swan necks have been around as you say for a long time and work great, just not on most of these reps... RG

No technicalese is lacking at all, there is no such thing as overwinding a watch as I already stated. If you can't move the crown anymore, the watch is "Fully Wound", if it's not functioning it's defective. But it's not defective because you can't move the crown anymore, if this was true, each and every hand wind would stop running once it was fully wound. Overwinding is the watchmakers way of lying to the layman, since it's not possible to overwind any watch... If the watch is running, then as it runs, the mainspring unwinds, which is why you can move it again as time goes by... Most people on the forum want to understand what is really going on with their watches. Understanding that "Overwinding" is a lie, is how we help them avoid getting scammed by shoddy watchmakers. No time to go revisit the thread, sorry... Wow, he has a watch problem, he didn't loose a first born...I don't want someone hugging me if my watch stops working... While some take you up on that offer, I prefer to deal with the purpose of the forum, Replica Watches and leave my ear wispering to real in the flesh people, not via the internet where no one really knows who any of us really are, or what we are... Enough of this off topic discussion, lets focus on what the member asked and stay on topic. Lets hope RWG can help him get his watch fixed. RG

Those are both interesting pictures, but have nothing to do with a running problem. For the record, it's impossible to to OVERWIND any watch, manual, auto, whatever. That is an old wives tale and simply not true, so it couldn't be the cause of your problem. Whoever told you that was blowing smoke your way... As for the swan neck lever being out of place, that has nothing at all to do with the watch running or not. The fact you moved it and the watch started running is nothing more than a coincedance. The swan neck is only concerned with the speed of the movement, and on most models is purely a decoration, and serves no useful purpose. Members do give out very useful and valuable information when it comes to watch problems. But expecting to diagnose a movement issue, via the internet, without actually seeing the watch in person, is next to impossible. Just because the particular advice given didn't fix your problem, doesn't discount it's value. It's better to discuss these issues in the open and on the forum than in private. This is how we all learn and help each other out, not on PM"s... RG

First question would be is the watch fully wound, did you wind it until you couldn't wind it anymore? If the answer to this question is yes, then you have another problem that is probably hard to diagnose from a distance. RG

Your welcome. I think he gave you some BS so you would go away...the pictures I posted show how to fix the hand if you find someone who can do it for you. I did this particular hand repair 3 years ago, and the hand has NEVER slipped after hundred's of resets. RG

What a shame that you just had access to the hand and could have fixed it... I certainly don't consider my self anything other than a RWG member and contributor willing to lend a hand. RG

Well I can tell you that it surely isn't the reset hammer, your watchmaker is not correct. And he's also not correct that it's not fixable, anything on a watch is fixable, which is why there are watchmakers... Is your 30 minute subdial hand resetting ok? Yes it is? If so then consider that the same hammer resets both the 30-minute timer and the center seconds...it either works or it doesn't. In other words, if the 30 minute hand resets correctly, so does the center seconds one reset correctly. The problem is with the hand itself, as andrew pointed out. I have fixed dozens of them, and it's always the same problem that has been around for 3 years now. I also suggest you find a new watchmaker, this is an easy simple problem to diagnose and fix, any watchmaker worth his sald should be able to sort this out in a few minutes. For reference, here is a hand, and here is the fix... RG

21,600 is 6 ticks and tocks per second, 28,800 is 8 ticks and tocks per second. The balance goes from neutral, 270 degrees CW, stops, goes back to neutral, swings 270 degrees CCW, stops, and goes back to neutral. This consititues a tic and toc, at 21,600 you have 6 of these per second...on a El Primero, you have 10 of these per second. RG

As already stated, check out the RWiki section the info is there... RG

Yes it is true that you can't change the date or time on a 7750 between 8-2, but that is not limited to only this model, that rule applies to any movement that does a slow date change. If you follow the golden rule of watches, never EVER force anything, then if you tried to set the date between 8-2, you would feel resistance, and following the golden rule, you would not damage the watch because you would stop trying to change the date once you felt resistance. The problem is that people force things, if it doesn't work, turn it harder...grunt... I see many 7750's in for service with stripped winding transfer gears, stripped meaning that the teeth are all ground off of the gear, it's smooth as a baby's bum. Now, if they followed the golden rule, this could not happen. But no, they decide to keep winding, eventhough there is a lot of resistance. This rule also applies to watch work, never force anything, and you can also add this rule to watchmaking, there are no short cuts - none. Follow these, and you won't break anything from mishandling. I covered in detail in the RWiki section how to use and handle all types of movements, the info is there for the reading. RG

If someone gets it, I'll gladly chip in towards it... I also have the ETA Factory 7750 course on CD...maybe I can trade copies of it as well. RG

Speed does not affect life, as long as you clean and oil the movement on a regular basis. Speed does affect how long the movement runs between windings...faster, shorter running... The difference in sound could be many things, what your hearing is the escape hitting the pallet stones. If the beat is out it could be a bit noisier, or it could just be the way it is with a particular movement. Oiling doesn't normally make a big difference in sound. RG

Size and speed go hand in hand with a balance wheel. The difference between a 21,600 and a 28,000 wheel is slight, and not easy to discern. A Zenith El Primero wheel at 36,000 is quite small. RG

It's either 18,000 or 21,600. Check out the balance wheels, smaller one is faster, larger one is slower. You should be able to note the difference between the balances, this will confirm your ticking estimate. RG

You hear recommendations from people who don't know what they are talking about. RG

Movements are user proof...meaning that nothing at all happens if you press the reset while it's running. They design movements to last and be user friendly. RG

Thanks, there is always a bright side... RG

My pleasure as always. RG
