The other day, a watch retailer explained to me that, for example, the ETA Valjoux 7750 movement is available in three different "precision categories", 7750 1A, 7750 2A, and 7750 3A. He also explained that the 1A movements are sold by ETA to watch companies like Breitling and Tag Heuer. The 2A's and 3A's are sold to lesser known and cheaper companies because they are not as precise as the 1A movements, although the parts are completely identical. ETA just doesn't want to go through the hassle or disassembling and reassembling the movements again in order to make them more precise. Wouldn't all this movement categorization be obsolete the moment the movements are overhauled by a professional watch repairman? And wouldn't a cheaper watch with 3A movement be just as good as a more expensive watch with a 1A movement after it has been overhauled? I hope my question makes some sense to you.

Thank you,

Common man
