Remove the back of a Seiko

Hello,

 

How to remove the back of a Seiko V157 0AC0 R2 watch? (problem o battery)

nothing to use a "Knif"...

 

Thanks for you help.

At the very minimum you need a good case knife, e.g. "Japanese type". In stubborn cases a lever type special tool may become a saving. Then the problem could become closing it, for which a small press is used.
My advice, unless you are willing to spend money for proper tools, bring the watch to a shop. Otherwise more damage than the one it has already suffered will be made.

One can only repeat what jdm has said, I notice the case is scratched by some one trying to gain entry without the proper tools.  a good case knife and a back press are a must. If you are into changing batteries it might be a worth wile investment.  See the attached

Agree with both above.

Also have you got a new cell yet?

They are particularly pricey for the V157 / V158 (£50+)

Good point. As with any quartz watch there is no guarantee that just giving it power it will work. Perhaps one should attempt with a long exposure to strong light, or temporarily powering from a regular battery before spending for a new rechargable cell.
