7750 Question

[esthera]

Hi I am new here and have spent lots of hours reading different articles and looking at different sites op rep guys.

Please correct me if I am wrong.

About the 7750. The original swiss version is very good unless it is used in a daytone model 2000 and later where seconds etc have been moved. This will give problems because of the extra gears.

Asion 7750. From what I read only the 28800 new asian version of the 7750 is worth looking at. all the previous version are sometimes in a poor quality. If the chrono is used life expectancy is even worse.

For the daytona version of the 7750 having the extra gears the same applies as to the swiss 7750 dytona version, in the end it will stop working because of the extra stress on the movement.

Up to now my conclusion is that when I would look for a 7750 model replica it could go for one with a swiss 7750 and have to pay $500 more than when I would go for one with the new asian 7750 28800.

Can someone tell me a bit more about this new asian 7750 28800. Does it require oiling when it is new from the box or can you just use it and have it serviced after a few years.

Can I use the chronos on the new asian 7750 28800 without the movement breaking down like in the old versions.

What is the accuracy on the movement, can it be trimmed to stay withing the cosc values of + or - a few seconds a day ?

I also looked at water resistancy. I see some rep guys offer a total inspection before shipping, oiling and 50 metre waterproof. As for the water resistancy, can 100 m be achieved of is this a general problem with replica's.
