Excellent watch, but not advisable to buy it on Amazon anymore
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.

Very good watch .
Looks similar to Seiko Sarb. Stunning . 6r35 movement. 70 hrs power reserve. Dress watch & field watch. Amazon India should reduce price.

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.
