Dutch, so the brothers are a couple of 100 km from me away. I cannot afford a Groenefeld, but superb that watch aficionados with enough money know where they can find Groenefeld. I own a Frederique Constant watch to have at least a semi Dutch watch, but i like my American Bulova more! I have a hate and love relation with my Frederique Constant, and a full strike honeymoon with an old cheap Roamer. The dial, and that is similar in both cases.
