At 39mm with the big lugs and great strap you can't go wrong dressing it up or down.
I use it is the summer as my main spots chic swim watch. It has held out very well and is not losing any of its cache.
I am a 42-44 mm guy with Panerai and recently converted to Vintage Rolex so I am all over the map on size but loving every minute of it.
