Further to my previous post, I do also use a Polar Vantage V.
When I’ve used it in conjunction with the Polar H10 paired with Polar Beat on my phone (and I’ve had no irregular reading issues) the HR readings are virtually the same, except that the H10 responds quicker to any sudden changes in HR.
However, whereas I have problems with the H10 in hotter (and therefore ‘sweatier’) conditions, the opposite is true with the Vantage V. In the winter months, the H10 seems to work fine, whereas the Vantage V is prone to having massive drop-outs due to what I can only assume to being the cold between my wrist and the device.

The watch should press tight and parallel to the wrist skin. If it is a little bit loose, you can forget about it. In doubt use the more tight fitting of the watch strap. (the watch must move with the skin). Guess even more important in winter as the blood vessels are a little bit smaler ...
