I am with you on this - with vibration alarm, it would be an instant buy. Vibration alarm on the wrist is so much less stressful in the morning, plus it doesn't wake up anyone sleeping next to you. I haven't used audio-based alarms in years.

Vibration is precisely what made me sell my brand new (sold out) Pebble watch. No matter the firmware or options (un)chosen, it would randomly vibrate at odd times of the day. Couldn't stand the constant distractions.

Casio G-Shock GW-M5610U back on my wrist where it belongs.

I'd guess it's likely battery and size consideration.

The only thing keeping me on my apple watch is the wakeup.

I'm disappointed because that's what kept me from buying the Amazfit Neo, which is a similar concept to this one. Without vibration it's useless to me. They get so close to a great product and then...
