Discover the Perpetual Calendar Watch: A Timepiece for the Ages


The world of horology is filled with countless innovations and fascinating complications, each offering unique functionality and aesthetics. The perpetual calendar is one such complication that stands out for its practicality and sophistication. In this blog post, we will delve into the intricacies of a perpetual calendar watch and highlight the exceptional Vostok-Europe Lunokhod models that utilize the YM86 perpetual calendar movement.

The Perpetual Calendar Explained

A perpetual calendar watch is a remarkable timekeeping device designed to automatically account for varying days each month, including leap years. This intricate mechanism ensures that the wearer never has to adjust the date on their watch manually. The only requirement is to set the watch initially by providing the date of the last leap year. Once this information is entered, the watch takes care of all the calculations, correctly displaying the date whether the month has 28, 29, 30, or 31 days.

Vostok-Europe Lunokhod Models with YM86 Perpetual Calendar Movement

Vostok-Europe, a renowned watch brand, incorporates the YM86 perpetual calendar movement in several Lunokhod models. This movement offers the perpetual calendar feature and includes a world time function, a 24-hour chronograph, a subdial displaying the day of the week, and an impressive 5-year battery life.

In addition to the exceptional functionality of the YM86 movement, the Lunokhod watches boast numerous features that elevate their overall design and utility. These watches come equipped with stand-up tritium tubes in patented "candle holder" reflectors, significantly enhancing visibility in low-light conditions.

The Lunokhod models are also designed for the rigors of professional diving, with 300 meters of water resistance, a screw-down crown, and a unidirectional bezel. The watches feature a durable 3.5mm thick K1 crystal, protecting against scratches and impacts.

Regarding style and comfort, the Lunokhod watches offer leather and silicone straps, along with the option of a stainless steel bracelet. Each timepiece is packaged in a professional dive case, making it an ideal gift for watch enthusiasts and divers alike.


A perpetual calendar watch is a marvel of horological engineering that blends practicality with sophistication. The Vostok-Europe Lunokhod models with the YM86 perpetual calendar movement are an excellent example of timepieces that incorporate this complication and offer a host of other features to suit the needs of the modern wearer.
