Yes the Swiss 7750 is still far superior than the Asian 7750 in terms of reliability and build quality.
Watcheden...if it sounds to good to be true it usually is
36,000vph vs 28,000vph
The advantage with the more accurate (alleged) timekeeping of the 36,000vph vs the reliability, accuracy and cost of manufacture of the 28,000vph is not enough reason for them to be more common these days.
Whether that will change in the future with technological advances in manufacture of the movements and lubricants...who knows?
I know of no rep movement that runs 36,000vph?
