The Konstantin Chaykin Stargazer is a reversible, two-sided “Wristmon” that pairs the watchmaker’s anthropomorphic dial design with astronomical and calendar indications. Konstantin Chaykin Manufacture lists 17 complications and 664 movement parts; its international premiere took place at Dubai Watch Week in November 2023. The dark side focuses on time and sky displays, while the light side brings together lunar and solar indications, sunrise and sunset azimuths, and a tourbillon.

What is the Konstantin Chaykin Stargazer?

Stargazer was created in 2023, the 20th anniversary year of Konstantin Chaykin Manufacture. The manufacture describes it as the most complicated wristwatch of Konstantin Chaykin’s career at the time and says 11 of its 17 functions are astronomical. It received the Revo Awards’ Best Astronomical Complication award, according to the manufacture. These are manufacturer statements, not independent performance assessments.

Chaykin said he wanted the anniversary watch to combine “ultra-complex watch mechanics, an anthropomorphic design and the theme of space exploration.” The result uses two faces, each organized around the familiar expressive features of a face: eyes, eyebrows, nose and mouth.

What does each side of the Stargazer do?

The case is designed to be reversed so either dial can face outward. The manufacture describes a symmetrical case with swinging H-shaped lugs, a double-sided leather strap reinforced with curved stiffeners, and a reversible buckle. This is a purpose-built strap and buckle arrangement, not a standard strap fitting.

Dark side: time, calendar and the northern sky

The dark dial presents mean solar time in a regulator-style layout. Its eyes show hours and minutes; the eyebrows indicate day and night length; and the nose displays the equation of time—the difference between mean solar time and apparent solar time. A retrograde weekday indication forms the mouth. Above it, a third eye carries a rotating star chart for the Northern Hemisphere. A zodiac ring and 24-hour mean solar and sidereal time displays add further context.

Light side: lunar and solar indications

The light dial’s eyes display a continuous astronomical moonphase and a solar activity cycle. A separate jumping indicator shows the four principal lunar phases. Sunrise and sunset azimuth indicators mark the horizon directions where the sun is expected to rise and set. At six o’clock, the tourbillon is framed to resemble an astonished open mouth.

How does the Stargazer moonphase work?

There are two different lunar readouts. The continuous display tracks moon age and phase, while the separate indicator jumps among new, waxing, full and waning. The jumping display is a simplified companion to the continuous one, not a substitute for it.

For the continuous moonphase, the manufacture publishes a deviation of one day in 122 years. It says the display advances once a day and uses a differential mechanism for driving and setting, so it can be corrected without affecting the watch’s timekeeping. That long-term accuracy figure is a manufacturer specification, not an independently verified result.

How do the sunrise and sunset azimuth indicators work?

The indicators point to the horizon positions where the sun is expected to rise and set. To use them, the watch must be held horizontally and oriented north with the solar-compass dial. The manufacture says the indication depends on the wearer’s geographical coordinates and that the mechanism is adjusted accordingly. Because the result is location-dependent, the relevant geography has to be set for the display to be useful at a given place.

What does the Stargazer star chart show?

The dark-side third eye is a rotating map of the Northern Hemisphere sky. The manufacture gives the chart a diameter of 6 mm and says it completes one rotation per sidereal day. A sidereal day is about 3 minutes and 56 seconds shorter than a solar day, reflecting Earth’s rotation relative to the stars rather than the Sun.
