These might just be the watches with the highest RRP for a Ronda 50x0-series movement - even the comparable Tag Heuers offerings are a couple of hundred pounds less (though admittedly, you won't find them for £300 or even near that)! Anyway, for what it's worth, the movement is among the best quartz chronographs, but except you're dead set on this particular design, you can do a lot better for the money, and even for less, even with established brands such as Victorinox, Wenger, Swiss Military Hanowa, or Roamer. Then for a bit more you have Davosa, Delma, Zodiac, Cyma, Doxa, Buler, CWC even, Edox - it's a very popular movement as you can tell.
