It's no doubt built and finished well and the movement and performance testing should ensure an overall quality watch. My issue is what it's competing with at £5k. That's a huge market with many top players in it and I know for sure that I personally would have this way down my list of £5k watches to buy. I think one of their issues is there's no in-brand distinction around quality in the way that Seiko and Grand Seiko works.
So it's a no from me.
