Why this movement matters
Power reserve
42 hours means you can take the watch off over a weekend and it will usually still be running Monday morning.
Frequency
28,800 beats/hour / 4 Hz is a common modern automatic rate. Higher frequency can improve stability in some conditions, but service access and long-term ownership matter more than Hz alone.
Certification
Not chronometer certified means the movement passed an independent timing standard before leaving the factory. That is useful, but it does not replace long-term ownership feedback or service network access.
Serviceability
Excellent long-term serviceability. The Valjoux 7750 platform is serviced by independent watchmakers worldwide. Parts are broadly available and service costs are moderate compared with column-wheel manufacture chronographs. Typical interval: 5 to 7 years.
Finishing
Circular graining on base plate, perlage on bridges, TAG Heuer rotor branding Finishing on tool-watch calibres is often practical rather than exhibition-grade. That is not automatically a flaw if the movement is robust and well regulated.
Movement honesty
