Just got a Seiko SBDX017, known to all as the MM300 or Marinemaster 300 - I bought it from the Forum, used but like new, (thanks Marek!) - now that is a very nice watch - it exudes quality and is certainly up with my 16610 - it is just lovely and wears great on a Crafter Blue Strap - CB03....... it is not at all "too big" or "too heavy"
I've not felt this enthusiastic about a watch since I bought my 16610 years ago, it's just beautiful
I'm so impressed that maybe the original SBDX001 could be added soon
