change asian 7750 for a real swiss one

[candide2424]

Hi everybody

I would be interesting in buying a Portuguese Chrono, I've looked through many topics about asian 7750 reliability problems, it seems to be a F...G movement. So, here is my newbie question: I wonder if it would be possible(sensibly) to remove it and to put a swiss one into the case??

This watch is too awesome !!!

thanks for your knowledge and wisdom

regards from France

Not possible, the Portuguese has running seconds at 6 o'clock. Swiss 7750 has running seconds at 9 o'clock.

thanks for your kind answer, excuse my ignorance but I was told there was a 7750 in the portuguese.

What's reality??

thanks for patience

The Portuguese has a modified asian 7750 movement with extra gears to make the second hand work at 6 instead of at 9. But these extra gears put too much stress on the movement and will break most of the time.

Too Bad, I'll have to wait for the next upgrade,( one is being sold in trade area) and I'm afraid of this reliability problem, I thought I could find a solution by replacing the bad movement with a good one.

For my culture, what's the type of the movement in the real one

thanks

On the gen there is a specific module which causes much less drag on the mainspring and movement. It may be doable but the results would be questionable as the rep gears are very inefficient. Seconds at 6 are largely luck and proper servicing as to how long it lasts. If your watch is currently working I would save your money and count yourself lucky.
