i have did some research on tourbillon watch recently. was thinking to get myself a pcs as the movement is damn nice.
for info, the lowest proper tourbillon will be SEAGULL. price range from RM12k to RM17k. RM17k is a retrodate, moonphase with 1 min tourbillon. SEAGULL supply more than 50% automatic movement to worldwide watchmaker. beside they are the biggest manufacturer to supply tourbillon movement to others watchmaker as well. brands that using a SEAGULL i can think of is perpetual. u can surf online to have a look on the design but offcoz the design is not really nice especially from the back.
swiss doesn't consider SEAGULL tourbillon as a proper tourbillon as their accuracy is not there compare to a swiss made. for a swiss made tourbillon, the lowest i have come accross is RM89k which is JLC & Chronoswiss. others brand like IWC priced at RM120k, Blancpain priced at RM160k, AP at RM250k. even a pcs of frederique constant also is cost more than RM100k.
