Quoting the Tweet you mentioned:
The average CRYPTOMAT sold for around 3 bitcoins... of course the price of BTC was in the $200's back in those days
While these are rare, I don't think you would get anywhere near 3
BTC for this watch at current BTC price.
I would offer something myself but I have no idea what a more realistic price for these will be. Maybe someone else can chime in?
I mean it is rare, you cannot buy them with fiat, I have never even seen one sold for fiat, they list their prices in fiat $880 USD typically retail but only payable in BTC at least back in 2014. I did pay ~3 BTC for it and it is a low number. I know some high profile Bitcoin figures owned these and possibly still do.
I am certainly open to offers...Hopefully maybe minerjones will chime in with more information on if any were sold as well 3rd party?
Hmm true. I see they're selling the newer editions for around the same ~$880 price range. I can certainly see the watch going for more than the original ~$880. My advice would be to look at it in terms of USD and not BTC or you'll get nowhere near finding a buyer. 3 BTC in 2014 wasn't worth the same as it is in 2021. Otherwise my old note3/note4 would be worth over a 100 grand today and my Steam library hundreds of thousands
Also, you'll be better off using an escrow on this forum and not someone off site
