This is a piece by Tag Heuer a Aquaracer Ref: Waj1112 a mix of rubber and full brushed stainless steel. A quartz version as they do make a automatic version as well, a very distinctive blue rubber bezel and blue dial with a watch case size of 43mm including the crown so not a small timepiece at all.  The watch is water resistant to 500 metres so could be used as dive watch. A distinct feature on this particular model is the date window is on the left instead of the right which feels a little strange as always used to seeing a date window on the right at 3 o clock.  The bracelet is used on various other Tag Heuer models but overall a lot of watch big, chunky and great everyday wearer for the lower end of the price range.
