Specifications



The official logos of the Army, Navy, and Air Force engraved on the dials of the Kentex-JSDF series are provided by the Ministry of Defense Joint Staff Office.
In addition, the JAPAN (national flag) mark is also designed on the dial, anticipating frequent interactions with other countries through overseas assignments and other means.
This watch is not simply solar-powered, but was designed to be one that would allow soldiers to feel the pride and courage of Japan every time they look at their wrist.

The solar panels that make up most of the dial seats are decorated in colors based on the uniforms of the Japan Ground Self-Defense Force. In addition, the design makes the emblem stand out across the entire panel. In terms of power supply, which is a key feature, the device has excellent charging performance not only from sunlight but also from indoor light, supporting activities in any field. |

The indexes and hands are coated with luminous paint, making them highly visible even in dark places. The Kentex JSDF Solar Standard, a model in the JSDF series equipped with solar power generation capabilities, is powerful enough to provide the power source needed to safely carry out missions day and night. |

The logos of the Self-Defense Forces, Navy, and Air Force engraved on the case back are official logos provided by the Japan Self-Defense Forces Joint Staff Office.
The Ground Self-Defense Force logo is based on the motif of "cherry blossom stars and cherry leaves," the Maritime Self-Defense Force logo is "anchor and cherry blossoms," and the Air Defense logo is "hawk, sun, moon, and stars in space and soaring wings" with the words "Ministry of Defense Ground Self-Defense Force," "Ministry of Defense Maritime Self-Defense Force," and "Ministry of Defense Air Defense" written above.
Additionally, since Kentex JSDF Watch is often used as a commemorative item for events or as a souvenir at the request of units or personnel, it is intended that blank space be left at the bottom for various characters to be added, such as the name of the ceremony, the year, the unit name, or the name of the ship.

The design of the case back may change depending on the manufacturer's circumstances. The photo on the left shows the design as of June 2018.

The watch is equipped with a reliable and accurate Japanese quartz movement.
The internal movement reflects the quality of "Made in Japan" - producing high-quality products at low prices - and embodies Kentex's simple philosophy.
![]() Introducing the solar-powered watch from the Japanese brand Kentex, part of the JSDF (Ministry of Defense) series. This is the only JSDF watch in Japan registered as a Ministry of Defense Headquarters contracted product.
Kentex continues to produce practical military watches with the cooperation of the Self-Defense Forces and by listening to the voices of those on the front lines. The case back features the official logos of the Ground, Maritime, and Air Self-Defense Forces.
This is the only watch in Japan that is registered as a "Ministry of Defense Headquarters Contract Product." The Kentex JSDF series watches are not only practical for private use, but also attractive for their cost-effective price range. Seibido Co., Ltd. Fumino Kawamura |

*The image is of the Japan Air Self-Defense Force, but the products sold here will be engraved with the Japan Ground Self-Defense Force.
The above is an example of engraved text as a gift to celebrate passing an exam.
I've always wanted a JGSDF watch. It's expensive, so I finally got it. I'll treasure it and use it for a long time.
I like the fact that it is a JGSDF specification, that it is also designed for night use, and that it has the Japanese flag mark.
If possible, it would be great if there was a tool that could adjust the thickness of the arms.
