Hi Ashley
Since I suspect there are few people who know more about the Chronostop than you, I will address this technical question to you. I very recently acquired a 145.009 with the standard dial orientation. It runs quite well on the timegrapher, but I still intend to have it serviced before wearing it regularly. I was re-reading your review of the model and I realized that my pusher only executes two functions, not three. The first push starts the chrono hand, and the second push resets it....foregoing the "stop" function. Is this a common problem, and would you know which components are responsible for the failure? I ask, because I would like to source the part(s) before I send it to my watchmaker. I appreciate you taking the time to entertain this request, thank you.
