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.
Serviceability
Swatch Group service network. ETA-based architecture ensures broad independent serviceability. Silicon hairspring reduces escapement lubrication needs. Moderate authorised service costs.
Movement honesty
