Polar Ignite - GPS Smartwatch (Black, M/L)

I bought this watch after open heart surgery to keep an eye on my heart rate so as no to overdo it during recovery. In my cardio rehab sessions, I occasionally checked my bpm against the monitor I was attached to, and found that normally they were exactly the same or within 1 beat of each other. Unfortunately, I found, occasionally, that checking my bpm too often (2-3 seconds apart) the readings on my watch read significantly lower than the hospital equipment. Just something to keep in mind while exercising. This watch is loaded with features! I have only had this watch for a couple of months and have only used a fraction of the features. I downloaded the pdf version of the instruction manual. The English version is 91 pages! The instructions are clearly written and nice to have if I’m not sure of something. The only other feature I wish it had is the ability to read blood oxygen saturation. I would highly recommend this amazing watch.
