Aha...you missed the first version of this little toy that was 'analog'. Check it out!

Now, this one mimics a 'smartwatch'...thus, the 'black' display is less telling vs the original that was stuck at 10:10.
No, neither 'watch' tells time.
There's a refill port on both that takes a couple of drops of smoke fluid.
There is a programmable time delay switch in the band...the smoke comes from the band also.
So, when you're in that Philippine jungle and want to have smoke come from your watch in those survival situations that you've mentioned, this is your 'tool'. The natives will love it...you just won't know what time it is!!!
Best wishes.
