Looks like a fancy watch from afar with none of the associated cost or maintenance. Exactly what I wanted. However the crown is kind of exposed and flimsy looking, so be careful to not get it caught on anything. Adjusting the band length is kind of fiddly, give yourself some time and good lighting to work on it. Also the connections are kind of flimsy so don't expect to be running around in the jungle with this thing.

Band included is for a fat wrist.

Surprisingly good quality for the price. Hard to read in dim light. If it lasts I'd buy it again.
