Watch heart rate all over the place

[okydokethen]

New watch.
Three days it's been monitoring heart rate and seems all over the place- 49 to 120.

How consistent should it stay a similar rate unless exercising?

I don't really know anything about heart rate, my blood pressure tends to be low (90ish/50ish)

What kind of watch is it?

Mine today is 63-124, some days it's 45-120 or 54-135, depends what I do. Yours sounds perfectly normal, it will go up if you get up and walk round going upstairs makes it go up a bit more, if I run upstairs to do something mine goes up to around 120

Oh ok that's reassuring!
