46mm

Tissot Seastar 1000 Powermatic 80 GMT  is a serious leader in the affordable dive watch category boasting a price point well under $1 000 and similar functionality as a traditional diver's watch.  The bezel is uni-directional for safer underwater functionality the dial is decorated with large luminescent hour markers and hands and the case is rated waterproof up to 300 meters/1 000 feet.  Anyone interested in dive watch ownership will find this model particularly collection-worthy.  Even more fascinating is that it sports a GMT function complete with a ceramic two-tone bezel with 24-hour graduations.  In some ways it reminds us of the Rolex Sprite because it has a similar bezel colorway. However this watch is much more robust measuring 46mm in diameter. We expect this Tissot to sell quickly.  Add it to your collection before it's gone.
