I dealt with him a while ago whilst considering a Grand Seiko homage/rip-off.
Really efficient to deal with but if you ask for something he’ll just give a yes or no answer without making a suggestion for an alternative so you can feel like you’re being a pain in the arse when you keep asking “what about xxxx, can you fit one of them to the body we decided on earlier?”
So make sure you know what you want, have pictures/model numbers etc to link to and if you want alternatives etc then specifically ask for his advice.
I’d go black and white but I have seen a white and black which looks pretty cool. Regardless of colour I’d get a sapphire crystal upgrade though.
