PERPETUAL TIME
The perpetual calendar is one of watchmaking’s high complications, and it has always been highly sought after by collectors. This popularity is partly because of the sheer complexity of the movement — it takes a skilled master watchmaker to assemble one, something that connoisseurs appreciate — and partly because it is such a useful complication. It displays day, date, month, year, and leap year, and doesn’t need adjusting for 122 years, hence the moniker perpetual. An annual calendar, by comparison, needs to be adjusted once a year at the end of February, and a simple calendar has to be updated every month of 30 or 31 days, plus February. The only caveat: don’t forget to wind your perpetual calendar or you’ll have to reset it.
