Hi all,
I bought an AP "End of Days" from m2m section, mine has the A7750 with non secs@12 mod, but with regular running secs@9.. I know back in the days the Chinese mod this with transfer gears to take secs @9 to @12. This mod was a time bomb and then with time some modders/WSs came up with a jewel mod, making it more robust. Nowadays I don't know what Chinese factories use but afaik new movements with secs@12 are somewhat more reliable.
Does anyone know what they actually do with these movements nowadays? also, if I'd like to replace my A7750 with secs@9 to a secs@12 one where can I buy it from? I'd try to use a local WS to perform the swap.
thank you all for reading!
