LUMINOSITY!!!!!!!!
I own 70+ watches and being able to see the time during low light or dark conditions is an important consideration. I admit most of my watches cost far more than this little Swiss Made gem, but only a couple of others can match its ability to be clearly seen in any lighting condition.
Well made, accurate, lightweight, oh yeah its 100 meter WR as well.
Note: I have few watches as small as this 40mm, but due to the thin bezel it plays much larger, now and then its about telling time and not about a fashion statement.
