Thought I'd come to give a heads up for possible future buyers. The gunmetal color definitely isn't grey like in the photos, it's aaalmost black and the strap is a lot darker too, sort of a muted army green color. It's not a bad combo per se, just not something I would've gone for, and as such the watch doesn't really match most of my jewellery or clothes, which is a shame. Massdrop should consider taking new, less misleading product photos.
Whatever material they used for stitching seems good, unfortunately the ends of the stitches are very scratchy against your skin, I had to file them down a bit. The crystal gets smudged surprisingly easily. Other than that, I really like the watch. It's heavy as hell but I'm a big fan of things that feel sturdy so I don't mind that.
