Garmin Vivosmart HR will do this fine - and also works as an activity tracker (measures no of steps, flights of stairs climbed etc) tracks sleep patterns (if you wear it in bed obviously) and also tracks resting heart rate (good measure of fitness/potential overtraining for endurance athletes)...
Or, if you're feeling a bit more spendy, there's the VivoActive HR - does all the above, plus has a GPS device that measures how far/fast you've walked/ski'ed/swam/cycled/canoed/ran and a whole load of other stuff... bit shorter battery life (especially if you usee the GPS a lot) but a big cheerful colour display, and a quick charge while you have your shower on a morning is generally enough to keep it going from day to day - then give it a full charge once a week.
For full analysis of the tracking, you'd need the garmin app on your phone (it's available for android or apple, in case you swap affiliations) - you can also use the Garmin Connect software on a PC/Mac which will synch when you plug the trackers into their USB charging stations.
I can personally recommend both of them, I had the old Vivoactive which was pants - display kept dying -after the third expired they gave me a free upgrade to the Vivosmart HR. However in the meantime, I'd bought the VivoActive, so now I kind of alternate between the two - the VivoActive is a bit "outdoorsy" for my working environment, doesn't really sit all that well with the shirt and tie look whereas the Vivosmart is small enough to fit under the cuffs...
HR Tracking on both is pretty decent, at least in general day-to-day stuff - optical tracking isn't quite as good as an ECG type Heart-rate belt when you're really working out hard - you get occasional spikes or lags in comparison (yes, I am obsessive enough to have paired he optical wristband to one Garmin Headunit on the handlebars, and a chestband to another Headunit, and compared the two while riding on the indoor trainer... they track pretty well - but the optical doesn't respond to "spikes" when you do hard intervals as quickly as the chestband. (it's kind of important for me to be a bit over-nerdy on this stuff, as I'm making a recovery from having a couple of stents fitted to a damaged artery I acquired as a result of complications after Pneumonia and Pericarditis a couple of years ago - the cardiologists are happy with the repairs, and encourage me to exercise, but it's only sensible to monitor things as well as you can...)
