I own a DM500 (an older quartz one - not PVD). Very well made watch - the case and bracelet are way better than I would expect for the price. Lume is excellent. I don't own any of the micro-diver brands for comparison but I doubt they'd be much better. I would warn you it's a heavy watch, one that you should prob try on before you buy it. Personally I love mine and it's one of FEW watches I own that has garnered compliments. Here's a pic of me wearing a DM500 and a monster (SKX) side-by-side. Sorry it's a lousy pic but hopefully it will help you.
Cheers,
NM
