Seiko quartz spare parts

[Preddo]

Hi. I'm currently fixing a Seiko quartz 5y23 8a60. The module as pictured is fried. I don't know how. Where can I get another one? Does anyone have a donner movement that I can use? 

Thanks WRT

Hi  the 5Y20/30/35 are cheap modules to replace entirely, depending where you are located  Cousins uk Watch parts will have them  or   Jules borel, Esslingers , Timesavers in the States   cost approx £5

Hi Just checked with Cousins uk   and the movement and parts are marked as obsolete, so maybe find a donor module on ebay will be the best choice.

Well the circuit module for the 5Y23 is Pt No 4001-527 and the coil number is 4002-522 if that helps. The same circuit and coil will also be found in the 5Y22, 5Y30, 5Y31, 5Y32 and 5Y39 movements, so this will widen your search for a donor.......
