Good looking watch!
Great price, excellent watch. What more can I say it's the "Tuna"! The steel shroud around the case makes this a very unique looking watch. The lume is excellent, looks great on a Nato/Zulu strap and keeps perfect time being a quartz movement. It wears comfortably despite it's size.

Great value high quality diver.
Best value luxury diver in my opinion. High quality movement, 300m water resistance, beautiful case design, nuclear level lume, and a comfy rubber strap all for around $1000. In this day and age that's a steal. It's a watch connoisseur's dive watch.

I love it!
I've been collecting watches for many years including 5 Seiko Automatics. This watch is in a different league! It's absolutely fantastic! It's built like a tank and I love it's styling. What else can I say?

Pictures doesn’t do this watch justice, it was surprisingly beautiful and just one slight mark on the bezel , other wise the watch was perfect

Seiko Does it Again
As usual, unbeatable value. If there's a better 300m mechanical out there at this price, I'm not aware of it.
