Have been eyeing this for a year for my husband. Watch enthusiast! It was perfect. Just like the picture. There are some complaints about the band. He felt it was stiff but tried to soften it up but he will probably get another metal band. Beautiful watch.

An excellent Seiko watch, sapphire crystal glass, very good power reserve. A really nice looking watch bought at a good price.

This was probably last good Seiko available online at a decent price. After March 2023, you won't be able to buy a good Seiko at a reasonable price on Amazon. There are importers who are charging twice (even e times of actual market price) the amount these days online. Please avoid online shopping to buy good watches.
