Highlights: The chronograph function handles single stop times and aggregate timing up to 12-hours and is a reliable companion even on long dives. Even with three subdials and a date and day display, the black dial is remarkably uncluttered. The external/internal rotating bezel with a SafeDive system designed to prevent inadvertent changes of the dive time boosts the practical use of the diver’s watch, as does the increase in water-resistance to 30 bar.

Really Great Watch
I picked up a Seiko for daily use and I’m seriously impressed. Keeps perfect time, looks clean, and feels durable. You can tell it’s built to last.

Feels Super Legit
Was nervous buying a Versace online but this one’s 100% real. It has a nice weight, and the face is stunning. I get compliments every time I wear it.

Amazing Deal
Scored a gorgeous Gucci piece for way less than retail. Brand new, boxed, and certified. Will recommend this store to my friends for sure.
