Watanabe Kobo Handmade Watch Automatic Winding Back Skeleton Jumbo Brass “Open Heart” Arabic Numerals Hand-sewn Belt [NW-BAM060-T]

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.

The naming of the mechanical movement is likened to the “heart of the watch”. Maybe it's because it's handmade that you can feel the heart of the watch.

The simple dial is accented by a small window where you can see the "heart (machine)". (The belt color in the photo is "brown") I feel like I can see the heart of the watch because it is handmade.

A self-winding mechanical wristwatch with a good naming that makes the watch feel like it has a heart, named “Open Heart”. Except for the part of the machine that can be seen through the small window, it has a clean and cool impression. That's why I feel that the small window that casually opens at 8 o'clock looks lovely. 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.

When the movement moves, it reflects glittering light and makes a casual statement



tasteful brass case



A warm atmosphere unique to handmade, where you can enjoy aging



Back skeleton specification.
By vibrating the crescent-shaped parts, the mainspring is automatically wound up.

The belt material is made of cowhide with a good texture and is thick and sturdy. It has much more durability and quality than the leather belt of a common watch.
