This is not a watch,obviously, this is the world’s thinnest 2,500 lumen projector. The projector is 43-mm (1.7-inch) / 1.7-kg (3.7-pounds) XJ-S46 projector blasts 2,500 lumens for ¥268,000 (about $2,263). The XJ-S36 brings the same form factor but drops the brightness down to 2,000 lumens for ¥238,000 ($2,010).
Projectors I used to know was bulky and heavy. This one looks like it could fit into a suitcase and carried along to meetings and what not. The Casio XJ-S46 also comes with a USB port for functional friendliness with a computer. Whoopie. Everything’s USB these days. There are also two other models to choose from, the XJ-S41 and XJ-S31 configurations. You’re going to have to ask others what those XJ numerics means.
