I owned the older Palm Watch.
http://www.amazon.com/Fossil-Abacus-AU5005-Wrist-Palm/dp/B00077ALQ4 show it but given it didn't hold a charge long I stopped wearing it.
I wrote (and still do) PalmOS apps so beyond the many watch faces it had, you could create your own.
Yes, I had a few. But the battery not lasting for months as it needs to was the end of it.
The phones have the time and work quite well at that.
