Narrative
Tracks the real synodic lunar cycle of 29 days, 12 hours, 44 minutes and 2.8 seconds — the mechanical approximation drifts by roughly one day per 122 years, which is why the correction interval on the case-back is dated that far out rather than promised as “perpetual” without qualification.
