If you look up Fields on companies house, there is an office in London N2, Fields Luxury, I think under which the brands are run.
If you think of dragons' den, where the inventors often talk about, "we get it made in China"...just wondered, possibly, if it's that way. A bunch of graphics people, send their "look/design" to China and they knock it up and they make their money that way and the legal work conditions is the Chinese are then allowed to resell same design in the East or as a generic OEM to others.
I don't know, just asking the question.
@Hammy60 I think it was did put links weeks back in the IW thread to a Chinese website offering "OEM generic watches" to order and customise, I think, but that could still be after the UK requirements were manufactured and then put in a catalogue to be resold as OEM generic for others to also buy.
