Seiko Caliber V158

One of the few unfortunate things associated with the more reliable quartz, solar charged watches is that pictures of the movement are rare simply because there's hardly ever any reason to open up the watch.

I previously wrote about the Seiko solar diver model SNE107 HERE which uses the V158 caliber inside.  A friend was kind enough to open up his Rail Road approved model which happens to contain the same movement and shared a picture with me.  Looks like a nice construction with a metal top plate and 2 jewels.
