For Sale is my Seiko Prospex SUN 023 Kinetic GMT
This has the black shroud with orange accents on the bezel and blue accents on the dial.

A Blog to Watch has a nice review of this model. From their article - "Being accustomed to the size of my SKX007 diver, the Seiko Prospex Kinetic GMT SUN023’s 48 mm width seemed rather daunting, but when I received the watch and tried it on, I found it to wear smaller than I expected. At 48 x 16mm, it certainly wears larger than an SXK, but because the bezel is just 42mm across, it doesn’t seem a full 6 mm wider. The additional width comes from the shroud-like external case element that also forms the lugs. On the SUN023 version of the Seiko Prospex Kinetic GMT, the outer case is black and visually less noticeable than the bright orange font on the bezel, which in turn makes the overall case appear smaller than its true dimensions."
Regarding the movement- "Sporting Seiko’s 5M85 kinetic movement, the Seiko Prospex Kinetic GMT SUN02X series uses a quartz movement with a rechargeable battery that is charged by the motion of your wrist which, when full, will offer six months of power reserve."

It's a fun, big watch that wears nicely. Comes with the OEM rubber strap and a generic Seiko box.
