Im told that the watch will be made avaliable thru your Official Audi agent in your respective country and not the Chronoswiss AD as it is an Audi product. (for Singapore at least). The Tachoscope comes under the arm of quattro GmbH germany (who manufacture the specialist RS/S/R cars in Audi), any order is therefore handled via them.
hope this info helps and that im not contravening any forum rules? (please feel free to delete this post if necessary)
kind regards as always
