Where are you wearing your 235?

Given the problems some people can have getting consistently reliable optical HR readings, thought might be useful to start a thread to share where you find wearing the 235 works best for you?

I'll start with this picture.

Here my 235 is "up the wrist" somewhat from a 630 and quite tight such that if I push and/or pull it from side to side it does not slide up or down my wrist at all.

BTW I put the 630 there in a more "normal" watch position not because I usually run with it there but to illustrate how far up the wrist the 235 is.

Good idea for a thread. My 235's HR has been flawless through 500ish miles - whether slow, fast, temps in the 20s through 60s, cold/windy rain, you name it. Here's where I wear it and, perhaps more importantly, here's what my skin looks like immediately after taking it off. I suspect a lot of people dealing with inaccuracies think that they're wearing it tight - and probably are compared to their day-to-day watch - but really aren't wearing it tight enough for the desired precision. I still have a faint watch imprint an hour post-run, even after I shower.

I personally don't have any discomfort wearing it this tight. I'll take the imprint over the chest-strap chafing any day.

This describes my practice as well. I will go 2 notches tighter (than normal daily wear) before a run which makes it QUITE snug and I wear it about the same place on the wrist (as the pic above). However, I will often slide it up the wrist ever so slightly (1/8 - 1/4 inch) ... my thinking has been to get the sensor out of the 'reddish sensor indent' on my skin (which I get from daily wear tightness as well) onto 'fresh' skin for my run. When I finish the run, I loosen it down 2 notches again for comfort. I have never had any real issues with HR accuracy, so I keep doing what's working for me.

I have occasionally forgotten to tighten the watch before a run, but have tightened it when I've noticed it bouncing around a bit on my wrist. On those runs, my HR seems somewhat erratic during the looser KM's. Snug is good!

Glad I've found this thread!

Had the 235 for about 2 weeks, did my first race last Sunday and HM was about 15bpm faster than when I ran the race with 620.

Last two runs HRM has been about 15bpm too slow. Looks like I'm not wearing it tight enough even though it doesn't move while running. Will try putting it a notch up.
