What distinguishes it
Look beyond the reference.
Day, date, month and leap-year indications describe a programmed calendar mechanism. The 24-hour indicator helps distinguish the calendar’s day and night.
For the enthusiast
Added complication changes the package: compare the 3.88 mm height and 38–48-hour reserve with the base 240. Calendar setting requires the specific watch manual.
