Optical sensor Damage??

Have any of you seen damage to the optical sensor similar to what is in the attached picture. I charged the watch just over a week ago and there were no crack, the watch has been on my wrist since then. The only reason it was off my wrist was to charge it and I noticed the marks. ciq.forums.garmin.com/.../1391464.jpg

    My 935 has got the cracks on the sensor - for those who have already had this, is there any impact on performance?  Mine does not seem to impact on the working of the watch - I have never found the optical sensor to be great anyway so use a Wahoo Tickr.  Having had issues with the altitude on previous models, I don't use the 935 for swimming (except races) - I got an old 920 for swim sets.

    I am part minded to ask for a RMA but if the performance is not impacted on not sure why I would be needing it (other then I appreciate that for items this expensive it shouldn't happen anyway)

    there is probably minor impact on the HR accuracy. But since the signal is very noisy anyway (thats just how it is with OHR), i don't think the difference is huge.

    On the other hand, i recently had some occassional HR spikes. When resting, the watch suddenly jumped to ca. 240 bpm. Could be a software bug though.

    This being said, if i were you i would take the chance and get a replacement device because this will improve reselling value. I am on my 3rd now and the guarantee period is over. So i have to sell it in this condition eventually.

    A friend of mine had the same. He went to the dealer and they gave him a new one.

    I'm having problems with my 9 months old 935. I wear it constantly apart from charging but change bands frequently. I've noticed a little crack around Xmas but the accuracy of the sensor seems about the same. I'm running with a slightly lower heartrate than a few months ago but that could just be my fitness improving. I'm really disappointed to have to do warranty repairs/replacement after how well I look after the watch...

    Well. I can join the club. Today I noticed the first cracks in my heart rate sensor. My watch is almost 3 years old, but I don't think that's a great excuse.

    Not that I really need ORM. It doesn't work for me during workouts and even the rest heart rate, which I'm very interested in, is not that reliable (Garmin reports a higher number than I regularly see measured, but thats not a sensor error but one of the many bugs in Garmins software).

    To bad the competition is also not very attractive. Suunto is either very big (Suunto 9) or a Android wear device (Suunto 7) and Polar still lacks navigation feature which I do use quite a lot. 

    Well, as long as the battery still holds I keep my FR935.
