Haven't seen them before. Nice clean and minimalistic design. 41.3x28.5mm is big enough to make them not look like a ladies watch. Hard to say anything about the quality with these crappy photos.
Not sure if I like the "Pie Watch" or the "Digital One Watch" more. The "Orbital Watch" readout is not intuitive IMHO.
BTW: this watch remineds me a bit of the Neolog A-24 II. Anybody have experience with that one?
