Interesting Submariner Homage watch with a Sapphire Crystal Glass for $99 from Amazon. Three colours: blue, green, black.
Pro: Sapphire glass much better than many Seiko watches with mineral glass.
Con: Quartz (battery) operated, not an automatic or self-winding watch. Brand and quality are not well known.
Several reviews online, one is below.
Nice photos; also a more expensive diver watch from the same brand
