The Black I think. Had a very limited production run before it was replaced six months or so later with the new one with the in-house movement. The other colours have been around for a few years.
Black bay black was launched 15th October 2015 with the tudor rose logo and " smiley " dial and discontinued March 2016. Some stockists didn't even receive their order. So very small production run and very few in UK. I'm Mr Omega geek and I bought one as is sooo cool. Deffo gonna appreciate.
Are these the ones with the rose logo? Any particular colour?
I had a look recently and there seemed to be a lot of red ones on eBay.
