Ricoh LCD watch reset

[ultraputa]

Anyone knows how to reset a Ricoh LCD wathc (Riquartz)?

I have 3 NOS ones and replacing the battery is not enough to make them work.

I think they are OK, because they are rally NOS, the inside of the watches are perfectly clean.

The problem is that they have 4/5 possible places to shortcut too much combinations for me :(

EDIT: Pictures of the Ricoh watches added. I will add pictures of the open watches later.

SOLVED!!!

No reset needed. There were some destroyed connections due to the age of the watches.

Time to take the welder and the thinnest wire I have to make they work again!
