Has anybody got this Montbrillant Datora?

[Agrippa]

Yo!

After looking at, and drooling over, far too many watches since I joined RWG I've decided that my first purchase simply has to include a Navitimer. There's way too many of them out there, particularly for someone as terminally indecisive as myself, but I believe I've finally landed on the Navitimer Montbrillant Datora and I wonder if somebody here owns one already and can comment on it? Just so it's said I'm not all that concerned with accuracy vs. the genuine article; to me build quality and durability is far more important.

Like most watches they vary quite a lot in price, but this is the one I'm thinking of getting: Montbrillant Datora @ PureTime costing $285. The problem is that in my noobishness I can't tell if that one is the same as, for instance, this one @ Watcheden at $325, or if they're not the same, whether the more expensive one is any better.

If anybody out there can shed any light on this I'd be most grateful!
