I own many independent pieces--Journe, Vianney H, Haldimann, KV, MIH, Ochs und Junior, and have owned others. Service has been excellent, never taken more than three months (I won't tell you tales of Patek and Lange on service time), and all reasonable.
Independent: The ability to think, design, and challenge apart from a large brand image. The ability to change and innovate in many forms without a 'burden' of history or brand efficacy. . . or committees.
I am drawn the the 'philosophy' of being independent.
Best to all,
Douglas
