Like any piece of clothing in your wardrobe, a good fitting watch is paramount to looking good. Watches fall in the 34mm-50mm range, my personal preference is the retro style, like a Rolex Submariner or Omega Seamaster. I find a vintage style sexy and timeless , which will not only look great, but in many cases will be less expensive than one that's brand new. What’s not to love about affordable class leaving you money to spend on the rest of your wardrobe?
Just make sure to pick up the right size for your wrist.
