On Day 3, did you notice whether the watch was still running or not when you recorded the time?

I would note that, for whatever reason, PC clocks aren't always accurate. I sync mine every couple of days to the atomic clock server, and find that it's not uncommon for the PC to be way off. For example, I just synced it while I was typing this, and it turned out the PC was off by about -57 seconds.

 

I usually use one of the atomic time websites like, Time.com, for a reference when checking a timepiece for accuracy.

That way there is no worry about computer or other variation.

Good luck!

 

The watch was still running when I recorded the time on day 3.

Also, I know my pc clock hadn't changed or was out, because I also compared my watch to other clocks and it was ~32mins slower.

What I'm thinking happened is that whilst I was asleep, the watch stopped, then when I moved my hand it started again (after 32mins).

The thing is that it should not stop at night if I've worn it for 2 days straight.

 

Doesn't matter that you wound it 30 times to begin with.... I would re-time it with www.time.gov over the next couple days and let us know the results. Sounds very odd it would be fine 1 day and not the next.

Yeah it is odd... and I'm sure it's done it before which is why I started testing it.

Anyway, I will sync it with timeanddate.com and post the results in a few days.

 

Update:

I set my watch in sync with timeanddate.com today at 2:30pm and all is going well. Then I take my watch off whilst I play sport for 1 hour. Come home and it's stopped. It started again as soon as I picked it up... but now it's half an hour or so slow (just like what happened before after 2 days).

So any ideas what's going on?

 

whats the temperature there now?
my vintage poljot was regulated to about +15 seconds a day, and it lost 30 minutes one day, nearly gave me a heart attack. it was -20 degrees celcius then, now its 2 degrees celcius and its gaining 5 minutes a day, gotta regulate the balance wheel again when the temperature normalizes.

 

I have an 8926 that slowed down and stopped after an hour or so the first few times I wore it - one saturday - I wore it to play tennis and it worked fine - never have had a problem after that but I only wear it about once a month - must have been some little wrench in the works that got shook out from the extra activity.

 

Ok thanks for the tips.

I'm pretty sure it didn't put the watch in a vertical position... just lay it down on a table on it's side.

Anyway, before setting the time do I need to manually wind it again so there's enough charge? Or just set the time and leave it on my wrist?

I'm really confused at this... it's like it works fine, but if the watch is off my wrist for half an hour it will stop.

At first when I got the watch I thought it was just because I never manually wound it to begin with (didn't know you could do this)... after I manually wound it, it was a bit better but still slows/stops.

 

I put the watch down on the desk beside me whilst I worked... it stopped after 2 hours!

Seems as though something in the mechanics is stuffed I guess?. Looks like a job for the watch repairer. It's too expensive to send back to Invicta overseas and I'm sure it will take ages to get fixed by them.

 

and the watch started moving again once you picked it up?

a fully wound watch will last AT LEAST 36 hours and manually winding the crown, 2-3 turns will last you like 5-6 hours. :think::think::think: to be on the safer side... how do you wind it manually? did you twist the crown clockwise or anticlockwise?

Have you checked the movement through the display caseback to see whether there is any visible fault(dirt, dust, loose little screws etc). but it is prolly best for you to send it to the local watchmaker.

 

I am assuming this is the Miyota movement, that's the standard in the 8926. I have five watches with the Miyota movements and none of them behave that way, regardless of the position they are left in when set down. I would think that something is awry. If you do send it to Invicta, plan on not seeing it for a very long time... I have heard their customer service moves slower than cold tar... If you have a local watch maker, I would have him look at it first. Sounds like it could be something jamming up the works. How old is the watch? Have you had it open? Unfortunately, if it does need a service it's probably less expensive to buy a new 8926 from Amazon:-s Seems the latest going rate for an 8926 is about $60-80. That's probably about what you would pay for a service.

If servicing an invicta cost as much as a new invicta, i would still get it serviced. It is better to have a decently serviced invicta than 2 poorly QCed invictas.

I heard that too, so i think a better plan would to send it to me.. you won't be seeing it for a very long time too(maybe forever), but at least i will thank you.. :-d:-d:-d:-d:-d

 

It's still losing time (I guess from stopping, thought I don't see it stop).

The manual says wind 30 times, then every week or two.... BUT what I'm going to do is wind it 15 times each morning manually and wear it all day/night. I'll see how long it keeps up that way.

edit: I've just noticed that quick/sudden movements of the watch stop it for a moment. I don't think I do it much, but very interesting.

 

It sounds like it runs ok but is not getting fully wound by the rotor during the course of the day.

So, could be you have a sticky rotor (does it spin freely?), or a problem of some sort with the clutch which prevents overwinding, or just a sticky mechanism in the rotor to the mainspring. Could also be some dirt in the movement or oil which was too liberally applied.

Try winding the watch and watching if the mainspring winds up in the movement during winding. Wind it like 40-50 times twice a day and see if it still loses time after 12 hours during the day.

The Miyota movements are variable in their power reserve and dont seem to have the reserve of the ETA automatics. Seems if they get 20-24 hours powere reserve on the Miyota that is about average although they sometimes get more.

Talk to a watch maker and they can probably look at it and give you an estimate for $10 or so I would think depending on who you have look at it and where you live. Get quotes on prices prior to having the estimate done.

As another poster noted, you can get a new one for around $60-$80. Look at Croton autos also. Their movements have lifetime warranty.

 

I wouldn't think that its the problem with the automatic mechanism.. the watch moved again after he picked it up and shaked it. It might be that he didn't get enough movement to wind the watch sufficiently for it to last the whole day.

But now he mentioned that sudden movements will stop the watch for a moment.. now that is interesting.

jefnando, I did some more research into this. Turns out it is normal and doesn't affect the movement.

Dragoon, the rotor does spin freely so I don't think there is an issue there.

I've just wound the watch 50-60 times and I will see how it goes. I think I will just keep an eye on the watch and get a better feel for how many winds last for how long before I take it to a watchmaker.

 

You might consider just leaving the watch on the nightstand or watchbox and see if it keeps time with manual winding without wearing it. 50-60 winds should keep it going for 24 hours at least.

Synch it up and let it run.

The only thing that is sort of puzzling is that is loses 30 minutes or so over 24 hours. Not really a balance or movement calibration issue. That usually is more like a minute or two kind of error.

Sounds more Like a dirty movement or lack of mainspring getting wound by the automatic mechanism to me.

 

Ok, yeah something is wrong.

Wound it 50 times this morning and set it to sync with timeanddate.com. Wore it all day. It's now 10-15mins slow, 12 hours later.

I'll be taking it to a watch repairer.

 

No sense repairing a movement that can be purchased new for $40. Hardest part would be refitting the hands. Depending on your confidence level I'd suggest tackling it yourself.

 

Hmm... confidence would be 0. I don't know much about movements or repairing watches. Any online information?

I will still get a quote from a repairer.

 

http://www.pmwf.com/Watches/WatchSc... remove and replace a watch movement/WS 11 How to remove and replace a movt.htm

Lots of info over by these guys.

 

So pissed off with Invicta!!

I took the watch to a watch repairer. They checked it and told me it was due for service. I said I'd only had the watch a month. They said well it must've been sitting in storage for a long time before you received it.

Anyway, to fix it they quoted be $230! It was something to do with the lubrication. I said can't you just replace the movement, and they said it would cost more to do that.

Ah. So now my options are to ship it to Invicta overseas and wait weeks upon weeks to get it back. Or buy another one. Or just buy a different watch.

It's such a shame because the watch is great.

Did you buy it new? If so, it's under warranty! Also if you purchased with American Express -- just use that to return/fix it for free. Also, if you used paypal there could be protections (not sure). Also, if you ordered from a company the company should accept return as it's clear it arrived to you broken. If you bought it from a person in the secondary market, then ask him to refund your money and send it back to him.

There are so many options here, please use one.

PS -- with this movement if it's a "lube issue" it should cost $30, not $200.... If you really need to get it fixed locally for some reason, then go to another place.

As I stated above, sounds like a dirty movement or oil misapplication vs. old oil which has lost its lubricating properties.

So, movement needs to be cleaned and oiled.

I think your choice of places to have the watch repaired may be the problem.

Let me know if you would like me to check with my watch repair guy. He would probably drop a new miyota in it for relatively cheap.

If it is an 8926...just buy another one and chalk it up to bad luck and look to get your money back from the original.

Good luck!

Thanks, yeah I emailed the place I bought it and they are allowing me to ship it back for a refund. So I'll buy another one.

 

Just an update for everyone:

Got my new Invicta 8926 last week and it's running much better than the last and keeping the time!

Just waiting on the refund from my other one.

But all seems to be good now. Thanks to everyone for your help :-!

 

Congratulations! some photos perhaps?
