Eberhard & Co. was founded in La Chaux-de-Fonds, the historic birthplace of watch-making industry by Georges Eberhard in 1887.
This complicated wristwatch, named Les Quantiemes (reference 30006), was made by the company in the late 80s. It is powered by an automatic movement with perpetual calendar and moon phase indications. Perpetual calendar is one of the most useful and romantic complications in all of horology. You can track the date, day of the week, month, year, leap year. Thanks to the varying lengths of the months and those pesky leap years, a perpetual calendar watch has a plethora of gears that turn multiple times per second to only once every four years or more. As such, this is a watch that, assuming you keep it wound, will not require any adjustments until the year 2100 at the earliest - leap years are skipped at the turn of a century.
