The time is determined based on dawn and dusk. This Edo no Toki clock is a modern reproduction of the timekeeping method of the Edo period.
Edo time literally changed with the changing seasons, a natural rhythm rooted in the Japanese climate.
Since we are often pressed for time and our days are often hectic, why not try to be conscious of the leisurely flow of time?

The time rules of the Edo period that were rooted in people's lives

During the Edo period, people's lives were very simple. They woke up to the bell announcing the dawn. They worked while the sun was up and slept when it went down. The sound of the bell and the sun were the foundations of life.
The day, from dawn to dusk, and the night, from dusk to dawn, were each divided into six equal parts, meaning that a day was divided into 12 parts, each of which was called an "hour," and was assigned the names of the twelve zodiac signs: Rat, Ox, Tiger, etc.
Naturally, the length of one moment during the day and one moment during the night differs, and the length of day and night also differs throughout the seasons, so at that time time was not a fixed length but something that changed according to the seasons.
At the time, Japanese clocks in Japan also used this time system (seasonal time system). They were uniquely Japanese improvements on mechanical clocks that were brought over from Europe during the Sengoku period. Naturally, they were very expensive, and were luxury items that only a select few feudal lords and wealthy merchants cherished.

Edo time is now recreated here.

Now, the "Edo no Toki" we are introducing here is a modern revival of the traditional Japanese clock that remains highly popular among collectors.
At the time, clocks were adjusted by craftsmen using complex mechanisms to compensate for the difference in time caused by the change of seasons. However, Edo no Toki uses 12 types of removable rings on a clock that goes around once in 24 hours, allowing for a realistic reproduction of the seasonal time system. Once a month, the rings marked "Rat, Ox, Tiger..." are replaced to adjust for the changing time. (This has already been patented as a simple method of displaying seasonal time for the 12 zodiac signs.)
The black part of the ring represents night, and the white part represents day. In addition to the names of the twelve zodiac signs, the number of strikes is also displayed, so you can instantly tell the time in Edo, such as "Hour of the Rabbit, Six Hours of Dawn."
Of course, the dial of the watch itself has modern hour markings, so it is designed so that you can tell the time in modern times.

The attention to detail adds a beautiful touch to your time.

The ring that shows the time in the Edo period is clamped and firmly fixed in place by a screw-down bezel (face). This seemingly tedious process is also part of the fun.
When you remove the ring, the luxurious record pull inner bezel appears, allowing you to enjoy a different look.
The crown (screw) on the side is large, creating a sense of presence and nostalgia. The single character "Toki" (time) is engraved on it. The beautifully rounded back is also engraved with "Edo no Toki," showing meticulous attention to detail.
The strap, designed to match the "stylish wristband," is made of high-quality cordovan (horse leather), a leather renowned for its strength and texture. The more you use it, the more it develops its own unique character.
The paulownia wood box packaging is both stylish and luxurious, making it a perfect gift.

How to read the time

1. Time in the Edo period (temporal time system)
The black band from Rooster to Tiger represents nighttime, and the white band represents daytime.

2. The number of bells in the Edo period This represents the number of times the hourly bell is struck.

3. Zodiac ring use month The ring is replaced every month, and this ring indicates which month it is for. (This is for August.)

4. Current time scale (fixed time system)
Just like a regular clock, it shows the current time.

5. 24-hour scale of current time The left half indicates the 12 hours of the morning and the right half indicates the 12 hours of the afternoon.

[Time shown on this clock]
