Not all movements are equal.
Compare a stock ETA 2824 like in my Steinharts and the ETA 2824 in an older Tudor Black Bay and not many people would begin to suspect they are the same movements.
Same goes for the big pocket watch Unitas 6498 inside some Panerai. You can buy one for £250 from ETA. It was the first movement I learned how to service. Fairly sure Panerai have fiddled with it before selling for $$$$
The SDR version on black rubber looks great in particular.
