I was fortunate enough to pick up the new, updated 2018 DSSD on Monday - big thanks to Ryan for facilitating it. I already had the original so I just took a few very quick snaps of them side by side, to highlight the differences for those who might be interested. Sorry the photos aren't the best, not a lot of time this morning!

The new one is on the right. The differences that I can see are: slimmer lugs, wider bracelet and clasp, end links are now flush with the lugs, small crown on the dial at 6 o'clock between swiss made, the writing on the dial appears smaller, and finally of course it runs the new 3235 movement with 70hr power reserve. I weighed them and the new version is 4g heavier.

Although the differences are subtle, they do combine to make this a nice upgrade over the original.
