Dear Volker
I saw your old post about this turquoise ROO color series. I’ve just picked up a purple one myself - had no idea these existed until recently. I’m trying to do a bit more research but can find almost no information about them.
All I know is that Philipps sold a red one in 2017 for about 23,750 Swiss francs and of course there were many colors (Apple green, orange, your gorgeous torquoise, brown/burgundy, purple, lime yellow, etc).
Do you have any information about these watches, or have you discovered anyone who does?
With kind regards.
Gordon
