Citizen Watch Co., Ltd., was founded in 1930 as the Shokosha Watch Research Institute by Japanese jeweler Kamekichi Yamazaki. The company was later renamed Citizen in 1937.

In 1956, Citizen introduced its first wristwatch with an automatic movement, the Citizen Parawater, marking a significant milestone in the company's history.

The Citizen Seven Star was introduced as a premium watch range in the 1970s and is one of the most sort after Citizen vintage range.

This Citizen Seven Star has a beautiful and immaculately preserved silvery-white linen dial, twin day/date window, 3D-styled silvery-white block Indices’ and dauphine hands that were given a deep cleaning and are now in excellent condition. Do note that the DAY WINDOW IS MISSING but does not affect the watch performance. I have already taken into consideration this issue when I determined the selling price.

Its cylindrical shaped silver case was buffed as best as possible without compromising its shape and lines albeit a few minor scratches that are barely noticeable to the naked eye. Its SS Milan mesh bracelet was cleaned via ultrasonic immersion and looks almost brand new! The acrylic crystal is original and was given a good rub to remove all age marks and miniscule scratches albeit a few hairline scratches do remain.

The crown is located at the traditional 3H position and is easily accessible.

The movement was given a general servicing and simple calibration on 28 August 2023. Its timekeeping is excellent i.e. ± 1 minute every 24 hours, and should be able to operate unhindered for the next 5 to 10 years thereby providing the owner peace of mind.

The case width and height are approximately 36mm (without crown) and 41mm respectively. The lug width is 18mm and the SS bracelet can accommodate wrists up to 21.0cm; hence it is suitable for men and the modern women.

Due to its age, this timepiece has not been water-resistant tested.

The pictures provided show the watch in very good condition. It has also been demagnetised to improve parts reliability, minimise wear & tear, and improve accuracy. The only drawback is the lack of documentation and original box. An aftermarket box or purposeful carrying case will be provided instead.

Bear in mind that this watch has seen many of the previous owners’ ups and downs in life, and should be cherished and preserved for the next generation to savour such engineering beauty.

Do also bear in mind that it will cost between S$ 80.00 to S$ 100.00 for a general servicing, an estimated S$ 40.00 for a basic calibration, and S$ 40.00 to buff the watch case and bracelet - these costs do not apply when purchasing this timepiece. So, if anyone was to sell such a timepiece at a low price yet claim that it has been serviced, one has to ask what kind of servicing was conducted, if any.

This is a beautiful timepiece that would make a beautiful present for that special someone.

This is a must-have for the Citizen die-hard fan, and in fact, any serious watch collector for that matter!
