The latest edition of the Blancpain magazine arrived a while back and along with the article on the new Fifty Fathoms I was interested to read the article on the 1185 chronograph movement.
I was amazed to learn that several un named top Swiss manufacturers have evidently copied the design of this movement including it's vertical clutch. Apparently this replication is so exact and extensive that major parts from them are actually interchangeable with the original!.
Immitation is the most sincere form of flattery or so the saying goes, but I am now curious to know who the culprits are. For instance do they include the new "in house" calibre for the Rolex Daytona as hinted at elsewhere?

The other part of the mysterious behind the scenes goings on that I find intriguing is that certain "manufacture" houses also supply their movements to other brands, some of them very prestigious names indeed.
I'm refering to the part of the market where the customer isn't only buying a watch, he is also buying into the Brands heritage and reputation. For example I would not be happy to learn that my BP had a movement supplied by another company. But I am led to believe that this happens at some very exclusive houses.
Yes, Lettres du Brassus is the Blancpain magazine. However, the statements about copying and imitation in the article are factual. I have personally laid transparencies of a rival brand's chronograph over the design of the 1185. It matched--as the article said "part for part" in the critical areas. This was not a case of close similarity--it was a case of striking similarity. As a copyright lawyer, drawing on 30 years of intellectual property law experience, I can say that the law would draw a firm presumption of copying with similarity this striking. Other brands have also admitted to careful study of the Blancpain design.
In the other case mentioned, involving the split second isolator, the brand's technical director admitted that he was "inspired" by the Blancpain design. The words are his not mine.
