How does KM Factory Patek Philippe Nautilus 5726-1A-010 Super Clone Watch annual calendar work

KM Factory Patek Philippe Nautilus 5726-1A-010 Super Clone Watch uses 48-tooth month wheels with long and short teeth for 30 and 31-day months. The date jumps by itself, so no monthly reset. February only has 28 or 29 days and the wheels can’t read that. So you manually fix it once a year around late Feb. Just one adjustment a year. This is a Patek Philippe Nautilus replica watch that fits the whole annual calendar into the classic case. The day and month windows sit right under 12. The moonphase and date are down at 6. The white dial looks clean and balanced. Among Nautilus clone watches, few annual calendars need just one yearly setting.
