The timepiece «Quartime» of the «Konstantin Chaykin» manufacture proposes a new vision of indicating time. The unique idea of the watch consists in the separated counting the time in morning, day, evening and night hours. Instead of dividing the day into halves – après midi and post midi (AM/PM), the Quartime Watch divides the day into 4 segments, reflecting how we actually divide the day in our minds.

The Quartime Watch divides the day into four 6 hour segments: morning, day, evening and night. This is how we naturally perceive the daily cycle: thus, the Quartime Watch helps us stay attuned to natural rhythms. Four times of the day, four quarters – morning, day, evening and night, the circle is complete. The name of the watch is formed from the Latin word «Quarta» – a quarter, and the English «time».

The hours are displayed in 6 tiny apertures on the face, and the time of day is displayed in a small window on the bottom.

The numbers used to mark the hours are 12-5 for the night, 6-11 for the morning, 12-5 for the day and finally 6-11 for the evening. At the start of each segment of the day the hour disc and the time of day disc both move.

Konstantin Chaykin invented a new movement to tell time. The patented caliber was developed and manufactured by the “Konstantin Chaykin” Manufacture. All 200 details of the caliber are created, decorated and finished in a complicated multi-step process. The completed movement is tested for 2,000 hours on special equipment, including robotics designed to mimic the natural movements of the human hand.

The new generation movement is contained in a classic case made of steel or rose gold. There are three models available: a classic model in a steel case with hour and minute hands and two models with a second hand on a secondary dial available in rose gold or steel cases. The dial is decorated with clou de Paris guilloche, and the hands are all blued in a traditional and complicated process, whereby the hands are heated to a certain temperature which creates the lovely shade of deep blue.
