I've made no secret of my love for the 5170... a great reference, not a hot watch currently which made choice of metal and purchasing options plentiful... I have been wearing the watch as my daily most Mon-Thur and I love it. Legibility can be an issue in dim light...but it just means I have a reason to stare at my watch for a few extra seconds!
