I do and it runs pretty accurate as far as I can tell. I don't time my watches for exact accuracy, but I've had no problems when I go to use it and when it's running it's pretty smooth. Not jerky like the Claro's were. I'm weird I actually like Neptunes. Have the one auto, one a bracelet, one 48mm one and one other.
I have a few 52mm Quartz's, of course they run well, and their silicone straps are like buttah. They are well fitting, despite their girth.
I was gonna sell them one day, as they get little wrist time.
