Don't forget to add the fact that the date wheel mechanism is actually a better design on the Asian version and does not have the same issue as the ETA one when changing the date between 10pm and 2am. Quite an ingenious design actually. Surprisingly the Asian's seemed to have improved upon a swiss design flaw!
Very true! Thanks.

The rep Portu has a polished case back whereas the genuine is brushed. A tell that can be easily altered....
A lot of you probably figured this out yourself but it is so easy and the result's are so good I want to share it with you guys.
You need 3 things:
- Jeweler screw driver
- Painting masking tape
- Scotch Brite pad (or similar)
Step 1
Remove your case back by removing the tiny screws with a jewelers screw driver.
Step 2
Mask the area of the case back that does not need to be brushed like the picture
Step 3
Brush the case back in 1 direction with the green surface of the Scotch Brite pad.
Step 4
Remove the tape and wash the case back with water and soap
Step 5
Enjoy!

~~~~~Please know that everything in this thread is my opinion and I don't want to present them as facts!~~~~~~~~
Well, as an old timer on this board I've seen the entire life cycle of the Asian 7750. From the early replicas with the old 21.600bph jewels version which were poorly finished up to the latest 28.800bph version and all the alterations the Chinese could make up.
One thing that clearly stands out when it comes to the Asian 7750 is that there are lovers and haters. The later are in the surplus! Especially the Asian 7750 with the running seconds at 6 gets a lot of negative attention. Not entirely without reason as the Chinese altered a perfectly designed movement (Valjoux 7750) to transfer the running seconds. They could have done that without compromising on the performance but they cut some corners and what you get is a relative unreliable movement when not taken care off properly. There are some modifications that can be done to it but I won't go in to that now.
What I do want to share is what a great movement the Asian 7750 is. Yes, it is great! In it's original configuration (12-9-6) it is at it's best as all the parts and functions work like they should. It is the basic configuration with the least chance of problems occurring.
So why is the Asian 7750 so notorious? Well theoratically it's not the movement itself but the condition under which it is assembled that causes most of the problems. 99% of all Asian 7750 movements are either dirty, dry, over oiled or a combination thereof. Ad poor quality checks /craftsman ship and you can ad loose screws, uneven hair spring coils, loose pallet stones and a lot of other stuff to the balance.
But what can you expect from a 300$ watch? In order to give us these beautiful reps for such low prices they have to cut expenses somewhere. If they would ad 8 hours of proper assembling and QC's the price would dramatically increase. And let's be honest. Most people don't care if their movement is clean and on par with the genuine.They are more concerned with the aesthetics. And for the few RWG nerds that are? There is The Zigmeister of every other watch maker.
So my point is: The Asian 7750 is in it's basic configuration a great movement and on par with the ETA 7750 if assembled and checked correctly. That does mean that sometimes parts needs to be cleaned, oiled or even replaced. But after that... just perfect.
Some nice pictures to conclude!
MarkHere's a random picture of an Asian 7750 as can be found in almost all reps. Dirty and shabby...
Here's an Asian 7750 after a full clean and oiling with the screws replaced by silver ones.
Compare it to a factory delivered Chronometer ETA 7750

WOW Jaw dropping lookers you have there.
I love what you did with the movements!!!! Those ETA gears make a real difference.

Not on a B01.
Yes for the Evolution.

Why would you want to remove them? I would say they are probably pressure fitted or a combination with glue. Removing them will compromise water resistance in the future if you don't reinstall them properly.
-
I know who's wacht in he sales section triggered you
It's indeed a marvellous looking watch. Nice pics and thanks for sharing!
Wear it well.

Wrong. In fact, there was a thread on TZ discussing this a few months ago with a number of members admitting having sold Daydates for their scrap gold value.
You're kidding? Those things are more worth melted?
-
Don't want to sound like an @ss but I really don't care. It mostly are those brands that nobody really cares about. The worth of these watches is made up by the amount of gold used and the movement (brand value=zero). I would do the same as most of the time these watches are hard to sell and assembled seldomly generate the amount they are truely worth. Ergo the best choice is to rip it apart and sell the guts because people just don't appreciate these watches/ brands. Sort of like some Frankens...
That's nature's cycle

Great result. I do however get the shivers of that dirty work bench/ cloth and him not wearing protective finger gloves .....
What did Domi use to fill up the old tube hole?

Thanks Lewis. Great info!!!!!!

How do we contact taka?

What's the point of this thread?
Just to share frustration with eachother so that I feel a little better. Haven't bought a rep for over a month now and I'm having some detox signs
It's just too damn quiet in the rep scene....
-
Can't wait untill the factories start up again and start spitting out new reps.......
Stupid raids!

Dior abomination
Josh has it listed now too!
-
It could be the night shift version from a real factory..
Exactly!!
or maybe Dior is way more popular in China then we realize.
-
Just saw this Dior at Angus' website and although it is not my taste it sure looks genuine. Is this like the recent released Hamilton Basjump? Looks like they are using genuine parts to some extend.
I couldn't spot a single flaw ( I have to say I didn't try that hard because I don't like watch anyway)
I merely want talk about the way things seem to change in the rep industries. Either the standards are getting way on par with the genuine or.....Swiss brands aren't as "Swiss" as they claim to be.
-
Funny. Personally I don"t give a rats @ss about the how good it blocks reflections. I want the blue hue. Aesthetics over function
-
Cool! Why go genuine right

This thread is 3 years old......

Just received new pic with timegraph result.
Please take a look again as I feel that those results are even worse.
rate: -016 s/d
amplitude: 267°
beat error: 1,0 ms
Shall I accept watch in this condition?
R.
What some crown turns can do huh
No seriously. If it was a 'normal' rep + or -15 sec/day is fine. As this one is supposed to be 'serviced' the rate is not acceptable. The amp is on the low side but I have had some A7750's that had a same amp after a full service. So if you believe the watch had a service this could be possible (rare but possible). The rate is the only thing that needs to be adjusted. But in all honousty.... I don't believe this watch had a service and the watchmaker did not regulate it correctly. You probably paid premium bucks for a 'normal' non-serviced rep. Just my 0.02.

great...was hoping it might be easy to work the jewels - easier than finding Asian parts...
Is there a side I should push the newly from?...dial side to back or vice-versa?
as always...thx!
Dial side or back side depends on the bridge you are working on. You always push a jewel out from the cup side of the jewel and you push it in from the flat side. If you look at the jewel from both sides you know what I mean
Good luck and let us know how it went.

Pop the jewel out with a plastic pen tip. You can push it right out. Getting one back in is a greater challenge as it needs to be seated straight. I've done it before. Before I bought a staking set so you can do it too! Just lay the bridge down flat. Position the jewel and push it in with a straight plastic tip. Push from the underside (flat side). Just do it gently, like making love to a woman
You got nothing to loose my friend
Why I love the Asian 7750.. and I think it does not get enough credits!

IMO $300 dollar is the 'consumer price'. That includes dealer mark ups, middle men, maybe pay offs (?) etc. If you look at the cost price of set watch it is much lower. The movement only being a small fraction of the total. So maybe $30 for a7750 whole sale in china?
And if you knew how a Swiss watch is assembled like for instance at Breitling and how our reps are assembled in dark sweat rooms you will realize that that the price of a clean and well performing movement is not only made up by labor costs. Environment, tools, schooling etc. are all equally important and contributing.
If you can get a complete new ETA 7750 powered watch for $300 please let me know where. I will buy a dozen! You can hardly get only the movement for that price
