I hope this hasn't been discussed here before - if it has, apologies.
Being a diver, I was expecting my Doxa Sub 300 Searambler lume to blow me away.
It's quite bright initially (charged via a black light) but rapidly fades.
Compared to my Seiko diver (or my now sold Submariner) it pales in comparison. Their glow lasts for hours.
Not a big problem - since I only snorkel and the rest of the time I'm a desk diver.
What's everyone else's lume like?
