Re: 7750 w GMT IS IT A TIMEBOMB

Here's the deal. When I started the 7750 thread several people were commenting about certain models being the problem. Well this is not like buying gens. A 7750 is a 7750 no matter what rep it is in.

I tried to explain that by making this comment on Jan 21st:

The ones that run seconds @9 are the best bet. But I have held the belief for some time that as more time passes we will see that it is not model limited. It's just a matter of waiting for more of these stories to filter in. And they will because regardless of any warnings people are still buying them by the truckload.

Now from the posts that are appearing lately what I said has come to pass. It is no longer model specific. Everything is being affected. Now the reason has to do with supply chains. The thing you have to understand is that movements are produced in the thousands. The ones that are coming in our watches at THIS moment were made as long as a year ago. Completed watches are the same way. They may have been sitting around in a bin for an extended period of time. That's why you open the box and there is rust on them. So why did the Skylands blow up first? Because it was a new model. When they began assembling the manufaturers dipped into the new supply of movements. Now as the old stock of other watches is depleted and new ones are built the same thing is happening with them.

Now I'm sure that there will be many comments here as there were there. Some of them will be the same as in the other thread. They will praise the 7750 and talk about how the 20 watches they have are outstanding. But they aren't thinking about what I said above. Even if the last one they bought was within a month of when the problems started the movement in them is from the PREVIOUS batch which WERE fine. I suggest you not let these comments confuse you as to the bigger picture here which is there is a problem. Are they all a problem? Of course not. We have already discussed that they either have problems or they don't. But there's no way to know which ones they are.

I expect that it could take as long to get out of it as it did to get in. That's about a year from the time the trouble started. So assuming they didn't make another bad batch behind it that's how long I would wait. Now you can take my advice or think I'm full of shit. Personally i don't expect people to stop buying them. They didn't listen before. For some crazy reason they never think it's going to happen to them. It's always the other guy. Why? Because they have this illusion that the dealer who is DROPSHIPPING it to them is a 'special friend' who is going to make sure THEIRS is right. How they could think that when the dealer never sees it i have no idea. But if you want to take the chance then go for it. You might get lucky. Hey if a monkey hits enough buttons he can turn on a rocket ship. Either way if you decide to do it then drop a couple of bills and have the thing serviced as soon as you get it. That will at least reduce the chances of a catastrophic failure.

I guess what you are saying Fakey is what my parents have been saying for years.........
'They don't make 'em like they used too!'

Thanks Fakey for the insight.

Re: 7750 w GMT IS IT A TIMEBOMB

I can only say this about the 7750 GMT Pam I got last month.
When h_U opened it up, he said there were a lot of metal shavings in there
and that is not good. But this is how most of them are shipped these days
and to think you won't get a bad one would be wishful thinking.
H_U cleaned it and lubed what he could but knowone knows how long it will run.
For now, it is running great though, not long enough to tell. It's my avatar, I wear it almost daily.

Re: 7750 w GMT IS IT A TIMEBOMB

For the experts...... What is the difference between the A 7750 and the A 7750 b1?

 

[takashi]

Re: 7750 w GMT IS IT A TIMEBOMB

The b1 is just another name for low beat movement.

As for the GMT modified A7750, I have seen problems in DW star (this is the modified part to run the GMT). Nevertheless, my PAM089 is still running (2 years old).

 

[hpy540]

So the low beat is the least dependable movement of the 7750's.......

 

[andreww]

So the low beat is the least dependable movement of the 7750's.......

Not really. The original low beats weren't that good, but by the time the 28ks came in to production the 21ks had become quite reliable. In fact, I found that after its initial release, there were far more 28k failures than with the 21k. I have no problem with either movement now.

 

[hpy540]

So none of thepams thathave the gmt function have a independent adjustment fo the gmt arm? Is this correct?

 

[horologie_unitas]

there are many beautyful watches out there with simple, reliable mvmnts.

please, tell me .....anybody ! ...who will work on a 7750 with GMT modul.

ok, i will be honest.....if problems occur....you will throw the watch away, or just not care about the correct function of the GMT...

who needs that anyway ?

 

[Dogma]

I know one guy h_u, LOL. But can't remember his name. :mrgreen:

 

[fakemaster]

I can and have worked on them. Unfortunately I had to stop due to the issues with them. Much like the eta clones they can vlow up if you breathe on them. And people aren't willing to toss something as easily as you might think. If something goes wrong they want you to fix it even if you have to drop another two bills to do it. Even if it wasn't your fault. All for a watch they paid $180 for. Totally unrealistic and totally sad because I really enjoyed it.

 

[horologie_unitas]

Fakey,

honestly.....can you imagine somebody takes a 7750 fully apart, cleans and services it, then lubing AFTER ETA STANDARD

all for $ 75 ???

please tell me ! honestly !

 

[fakemaster]

Honestly? I have. In fact I have done these types of services for people for free. But I am not in it for the money. But most are. And you are right. They would not touch it for less than $150 or more.

 

[horologie_unitas]

i have had a look at the ETA datasheet for this movement....

to be honest, it takes me a few hours to take a 6497 apart, clean it.....assemble it, lube it....

not to mention the various oils you need ( and their cost )

----but doing that to a 7750 ??

no way.....i would ever do that. taking it apart....anytime. but thats it.

i only touch what i am 100% sure i can handle.....and i work slow. been through some pocketwatches.....6497's,

and half a 2824. to much stuff can go wrong......get lost, break.....

i doubt that ziggy asks 75 $ for a standard 7750 service.....with lubing correctly.

i get what i pay for ?

Ziggy will, no probs. The GMT hand on these is set using the date set gears and this has on occasion been problematic. This is usualy unrepairable however this seems to be their only weakpoint. A good service imediatly usualy sees good service from this MVT.
