I think the watch-sizes will go down soon. We have all become "speed-blind" with bigger and bigger watches. It's like with everyting else in fashion - it will peak - become to much - and then go back to more normal sizes again. Look at the height of shoes in the 70's, they started out looking cool, but after the peak they just looked like clown shoes. And we don't want to wear clown sized watches, do we?
Also remember the personal taste is the important thing here. If you like it -wear it!
