In no case, I do not advocate TTF with all their shortcomings, and even more so, a clone is preferable to any movement with a different type of control, but it should be noted that using the А7750 and deco plate, TTF does not greatly violate the overall thickness of the case, all the more so, that the PAM1157 has a sold caseback, and for the PAM1359, the use of the P.9000 clone would be completely inappropriate due to its appearance.
I should also note that even for the P.9000 models, the clone was not a 100% solution either: it is not at all difficult to distinguish both externally and functionally (due to the absence of resetting the second hand to "0" when setting the time), therefore, externally, not much more difficult to spot it through the transparent caseback than the decorated 7750, which depicts p.9010.
I am not at all against VSF and clones, and again, I am not defending TTF, and my whole thought is that there are flaws everywhere, and the question of personal preferences in their adoption is very personal.
VuA returning to the topic, I am extremely interested that the PAM1157 has a dial texture. If that glossiness of GEN is not there, then there is no point in discussing the specifics of the 7750 ...
