Garmin fitness band, with wrist based 24 hour HR monitoring, and, making it actually useful, GPS, so you can use it as a running and, albeit limited, cycling watch.

I found a shop display unit at Amart Sports in the Brisbane CBD for $199, not sure as to field stocks but are available online. I have an original model Vivoactive (the actual watch) and looked at the Vivoactive HR and found the LED HR unit to be uncomfortable, but I've had this on pretty much constantly for the last 30 hours or so and it's fine.
Pricing window seems to be $240 - $320. Garmin list it at $349 (https://buy.garmin.com/en-AU/AU/p/548743)
My Vivosmart HR+ usually needs 5 minutes or more to get GPS information. Which is useless to me.
HR tracking is also useless with its incorrect reads.
Another cons is it doesn't allow setting for multiple alarms - I just want to set one to wake me up, and another to remind me of taking the pills, but it can't.
