If you have a lot to spend on a special man and he is into more design than function then you might like to consider these chunky watches from Diesel. I say they are less functional but in fact they look to have function. I think the drawback with chunky watches is the comfort of wearing one for an extended period of time. But for me they look great !
The Big Daddy range are the ones that have that massive designer styled look while original and chunky.
There are others in the Diesel stable that might also attract like the 'grand daddy'
