Nicknamed the “Perpetual Calendar,” this Raketa does things its own way. Unlike Swiss perpetuals with complex gearing, this watch uses a clever dial system operated by the crowns.

The bottom crown rotates two discs:

• Top disc – days of the week

• Bottom disc – years (up to 2012, though it works with any equivalent year in the leap-year cycle)

To use it, you align the current year with the column of the current month on the lower half of the dial. This instantly syncs the upper half of the dial, displaying the days of the week against the correct dates of the month—just like reading a miniature calendar on your wrist.

With this system, you can check ahead—like seeing that June 29 falls on a Saturday—or even work backwards to identify which leap-year cycle a particular date belonged to.

A functional oddity, this Raketa blends Soviet ingenuity with practical utility, offering a tactile and mechanical take on the idea of a perpetual calendar.
