I really like the watch. Great work.
One of the things that popped into my mind is that it would be really cool to have Block time there, either instead or along the "normal" time.
It would need to be connected to the internet though, either directly or indirectly, for example with a Bluetooth connection that syncs with your phone or laptop, or an NFC connection where you need to tap your phone to update.
Thinking about it, it might be a bit too much hassle to add the block time, but it would be so cool to see it on your watch.
