On offer today is this lovely Glycine ref. GLO261, a collab with Gnomon Watches ([details here](https://www.gnomonwatches.com/products/combat-sub-42-vintage-black-ref-gl0261)) The Combat Sub holds a special place in the market for one very important reason: it is the thinnest automatic dive watch in the world at just over 10.5mm, including the AR coated sapphire crystal. Purchased secondhand here on WatchEx, sold by me a year later which I came to greatly regret, so I bought it back. It's slipped out of rotation with a couple new watches so although I'll probably regret it again, it's back on the block. Prior to selling it the first time, I installed a lumed sapphire bezel insert and it really takes the watch to another level. The stock bezel is also included. From my quick searching, there don't appear to be any of these for sale (in this colorway) right now, and the few blue dial versions were still going for much more. I honestly believe the GL0261 is going to be a little tougher to find in the coming years; add in the lumed sapphire bezel and it really is a unique watch. Overall condition is very good, I would rate this at an 8.0/10. There are a few minor blems right where the bracelet meets the end links, and appears to be unavoidable with normal wear. Some faint and minor desk diving marks but nothing severe. I’ve uploaded a video that I hope shows the condition well. Crystal is still pristine.
