Wow, this thread has taken on an unfortunate like of its own. Good watch smiths are extremely hard to find. Although the Hublot and Pam are reps, the hublot has a clone DD2020 chrono module and the Pam has either the same movement as the hublot or it has an A7753, which (in either case) makes these trickier movements to work on than a standard 7750.
I had my Hublot (H-Factory version) serviced locally by my usual watch smith, who tried hard but couldn't get my hublot right. I brought the watch to another smith i have used for gens and asked him to look at and let me know if he could fix (this guy actually worked as a senior tech for Rolex in switzerland and later for Richmond group in NY. He now has his own shop doing specializing I vintage and ultra high end watches and working under contract for a number of ADs). He is expensive, but he can fix anything (it just isn't always worth it). I paid him $50 just to tell me what was wrong with the watch. In his view, the movement on my hublot was an elegant design, but not well executed. The parts are made of low grade materials and aren't well finished to begin with. These imperfect components are then assembled by workers that don't have the skills to put it together correctly and are assembling the movements in a rush and in a dirty environment. The only way to get it right is to tear it down completely, replave and upgrade all of the jewels, replace most of the gears (many of which were already showing signs of wear and deformation), replace every spring and bearing, refinish the components as needed, clean the component a second time, then reassemble. The estimated cost was have been around $500.00, and could have been as high as $700.00 if there were surprises. Not worth it for that watch, so I sold the watch at a huge loss.
