Why this movement matters
Power reserve
72 hours means you can take the watch off over a weekend and it will usually still be running Monday morning. That is a genuinely useful reserve for a daily wearer, not just a marketing rounding exercise.
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 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
Good through Longines / Swatch Group service channels. Independent servicing may be less straightforward than common ETA/Sellita three-hand movements because this is a modern GMT calibre with silicon components.
