it was actually very simple. i put the watch onto a piece of thin ice at the edge of a lake so you can see the water underneath it. i then used photoshop to change it to B&W, changed some of the highlights a bit and that was it. its one of my best pics i think and i've taken 1000's.
if it wasnt my pic you were referring too then i apologise, but you got a free lesson in photoshop
best
