Elliot Brown Watch Bloxworth Chrono Black Cyan Bracelet 929-018-B07. A classic tech diver chronograph designed for those who like a little more function, the Bloxworth is a true go anywhere, do anything watch. Its Swiss made 13 jewel chronograph movement has a three year battery life (subject to how much the stopwatch function is used) and is secured inside our proprietary shock absorbing steel movement housing. The 44mm diameter case is pebble like so it wears beautifully even on smaller wrists and is machined from solid 316L marine grade stainless steel.
