The Noobmarina was first sold by TTK who is no longer with us, it was at the time the best cheep sub with a slow beat asian movement and is a quality watch and renound for having the best dial, the same factory makes a number of other watches all being a very good quality, read Bytors reviews to finf out more on this.
WM9 is not a dealer on this board but has his own site as far i know, he also makes a very good sub but i would say that the Euromarina sold by eurotimez is a little better (But i am no expert in this area)
I hope this helps
