Seiko 7A28-7040 Quartz Chronograph

A friend sent me his 7A28-7040 to bring back to life.  Having never seen one in person before, I was happy to help him out.

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.

Recall -- Seiko Solar Chronograph Diver

I noticed on the Seiko Japan site there is a recall on the bracelet models of the Solar Chronograph Diver models.  Apparently the end links can deform from violent force.  The notice is limited to products with V175-0AD0 and V175-0CF0 stamped on the caseback.  Owners are encouraged to contact their local customer service.
