Happen to get my De Ville Co-axial chrono in 2003, among the first batch.Very competitively priced given the FP 1185 based chrono enhanced by co-axial escapement vs other brands -Blancpain, Franck Muller ....Like most 0 samples, happen to have problems with chrono functions, fixed for free by Omega and no problem whatsoever for over 10 yrs. It appears this model was completely ignored and rarely mentioned and articles about the phrasing out of Cal 3313 with modified 7750 movements (confusingly identified as Cal 3330). Given the fact that nowadays 70s mediocre brand carrying 7753 are asking for crazy money. IMHO, the model carries more Bang for the Bucks, just my HK 2 cents.
