Heart Rate taken when not wearing the Watch

While scrolling through the glances this morning I noticed that a Heart Rate was taken 11 minutes ago with my Heart Rate at 111. I don't know how this is possible, since I was not wearing the watch, but had recently taken it off the charger after waking up.

I think the feature is working well and is accurate when I'm wearing the watch, though. Is it normal for the Watch to take Heart Rate measurements when not being worn, or is 111 the last measurement from when I was wearing it yesterday, but perhaps the timestamp is off? I was not active last night prior to taking the watch off (getting ready to sleep), so I don't think the 111 is accurate.

It may be an anomalous sensor reading... Wouldn't worry about it unless you notice it frequently.
