I bought this watch from concepta about 2 years ago. The watch was running excellent, but i decided it was time for a service to keep things nice, clean and in perfect condition.
As i was discussing the details with my good friend and watchmaker Aris, i saw an opened a7750 on his bench and i thought lets compare the two..
So here it goes:
1)
2)
3)
Automatic winding mechanism (different wheel)
4)
5)
6)
movement without auto winding mechanism
7)
8)
Small difference in the cut-outs
9)
10)
11)
12)
An area of the plate is removed, the module for the transfer of seconds fits here
13)
14)
The module for the seconds tranfer
15)
16)
Reassembled!
Apart from the things noted, the decoration was different and also the finish of the gen movement. The a7750 counterpart was surprisingly good but not up to par with its Swiss cousin.
Forgive any mistakes i have made, as this is my first attempt to contribute to this forum i thought its best to let the pics speak rather than me.
Regards
Angelos
