Mr. Masaaki Watanabe of Watanabe Koubou is a watchmaker who makes watches one by one by hand at his workshop in downtown Tokyo. We have worked on many watch works that are full of warmth and a tasteful expression unique to handmade.

Mr. Watanabe does everything by hand, from making watch parts such as cases, dials, and belts to assembling them. There is a wide variety of products, from simple designs that can be used for both casual and business purposes, to unique models that incorporate originality and ingenuity. Watches created through a very time-consuming process give warmth and healing that ready-made products do not have.

For the material of the case, we use materials such as brass and silver that can be enjoyed over time. The leather belt is made of genuine leather that is thick yet fits well, giving it a sense of quality and presence. With the flow of time, you will grow attached to it - it is overflowing with such warmth.


An open heart model that allows you to see the movement of the machine from a part of the dial.
It is a soothing work that moves like a human heartbeat.


The accent is a small window where you can see the “heart (machine)”.
(The belt color in the photo is "brown")


With the warmth that can only be achieved by hand, the watch seems to come to life.


This watch named "Open Heart" is a self-winding mechanical watch with a small window on the dial.

The movements of the movement can be seen through the small window, and it looks like a human heartbeat. You will be healed by the sound of the second hand that sounds quietly, "Tick, tick, tick, tick, tick, tick".

The hand-wound type winds the mainspring by turning the crown manually. In self-winding, the crescent-shaped part called the rotor of the movement rotates when worn or when the watch is shaken, and the mainspring is wound.

You can feel the time while enjoying the expression of brass with a rich texture.
