I have had two of them--a Monaco YS, and a Ti model. They were both purchsed new. The Monaco's minute register never advanced past the five minute mark. Thinking that I had a fluke bad experience, two years later I purchased a Ti flyback that had an even more ridiculous problem--the center seconds hand was not mounted on the center arbor with enough friction such that with every reset to zero the seconds hand rotated more and more to the left of 12 o'clock. At the end of the first day, to my dismay, the center seconds hand would reset to the 10 o'clock postion!
The FP 1185, while interesting in concept, is IMHO the least reliable chrono movement out there. One could argue that the problems I had were secondary to poor QC at BP (which I would not disagree with, BTW) but I think there are intrinsic problems to the movement as far as reliability and ruggedness. As evidence, the derivative Omega 33XX movements have had significant problems also. I had to chuckle when the first owner's reports emerged because not only did BP screw more customers indirectly, but this time it had caused shame to its older Swatch group sister.
One might think that this was too small a sampling size for me to draw such a conclusion. I argue that it was two separate watches produced at different times (I bought my second Flyback two years later) yet both had problems. That's not unlike the random sampling that a company must use to ensure good QC. I will never be a Flyback purchaser again and I may never purchase a BP again. Search the archives here and at other websites and you will see a disproportionate number of posts questioning BP's overall reliablility. No other brand forum exhibits this amount of uncertainty; I'm sure that I am not the only previous owner that can give you insight as to why that might be the case.
Again, this is my experience with the Flybacks and this post was not crafted to troll. You are buying an expensive watch and should be provided with all opinions. I will say that in fairness that I had an Aqualung on a rubber strap that did very well for me and I do miss it indeed.
