Not gonna lie, I was really worried about the sizing. People online talk a lot about how much smaller the 013 is against expectations, given its dimensions. For me, this is the absolute perfect size for a watch. It's crisp, classy, and (to me, at least) more sophisticated than something larger. I think it'll age well as a permanent piece in my collection. Mind you, I've got 6"3/4' wrists, so I'm not a big guy. If you're struggling to decide between the 007/9 and the 013, I'd just look at the watches you're used to wearing. If you are used to wearing watches 42mm+, the 013 is gonna feel really small for you. On the other hand, if you usually wear anything 40mm or below, it'll fit great! Classic!
