Why this movement matters
Power reserve
60 hours means you can take the watch off over a weekend and it will usually still be running Monday morning.
Frequency
25,200 beats/hour / 3.5 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
COSC and METAS Master Chronometer 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
Best handled through Omega authorized service or qualified Omega-capable watchmakers. Do not describe servicing as cheap or simple without a direct source.
Movement honesty
Movement honesty classification pending editorial review.
