The Drive Extra Flat retains the same shape and basic design codes, but with some pretty serious changes. First off, the case has been sized down just a hair to 39mm and it's crazy thin at just 6.6mm. It's a small change, but it makes a huge difference on the wrist. The watch is also only available in white and rose gold, with no steel option on offer. The caseback is closed as well (which gets you major bonus points on a watch like this) and the overall shape of the case is extremely clean and crisp. It's not a major selling point, but the grey alligator strap that comes with the white gold model suits the watch perfectly too.
