This is another Indiegogo crowdfunding product but it’s done, it’s passed its threshold and will be produced. Ritot is a projection watch, reportedly the first such thing, but it’s easier to show you. Have a watch, so to speak:
For some reason it reminds me of my very first digital watch where you had to hold down a button to see some red LED readout. The watch band for this is rather nicer than those but still, I’m not sold.
Plenty of other people are, though, so if this is your bag, go pledge on Indiegogo to get it early or cheaper or with some rewards.
