Thanks Lobster,
by the way, i just tested the Lume, I 'charge' it with my 120 lumens flashlight for +- 15 secs,
then count how long does it last.
and it remain visible bright for 4 minutes 50 seconds
then start diminishing - I need to turn off all my lights and computer screen, just to be able to see the rest of the lume.
then after +-60 secs, it all gone to darkness.
Quiet disappointing for AU$4K watch. But again, this is for Dress Watch, not for diving, so I guess I cant complain.
