SEIKO Watch Co. - Seiko Watch Corporation is a Japanese company that specializes in the production of wristwatches, clocks, and electronic devices. The company was founded in 1881 by Kintaro Hattori in Tokyo, Japan. Originally named Seikosha, the company started out producing clocks before moving into the production of pocket watches in 1895.   
 
Seikomatic  - The first Seikomatic debuted in 1960, marked by its simple design and functionality, but laying the foundation for what would become the luxurious Grand Seiko line. Early models featured waterproof cases and a variety of interesting complications, such as calendar, slim date, and auto date. 

The original Seikomatic, with its automatic caliber 603 (later renamed 6201), ran at 18,000 bph and was available in 17, 20 or 30 jewel variants. The date complication first appeared on the 24-jewel 394 Seikomatic Selfdater of 1962, which was later renamed caliber 6205. This evolved into the distinguished 39-jewel 395 Self Dater 50 Proof in 1963.

Vintage watches are traditionally smaller than today's watches. Men’s watches typically measure between 29-36mm wide (some larger, some smaller) excluding the crown. In the listing details we typically try to do our best to list all pertinent dimensions of a watch. If you don't see it, or we failed to do so, please reach out to us. Women’s watches from the 1900s-1970s were also much smaller than today's offerings. Please also feel free to ask any questions you have pertaining to size. 

We prefer to shoot photographs outside when weather is permitting. However, when we shoot indoors, please be aware that we shoot our photographs inside of lightboxes that are lit with 360 LED bulbs. This indeed magnifies any flaws. Usually, they are much less obvious to the naked eye. Having said that, we never photoshop any of our photography, remove blemishes, etc. We adjust the lighting, when necessary, but what you see is what you are getting, and we take pride in that.  

The condition is pre-owned.   
The item may have some signs of cosmetic wear but is fully operational and functions as intended. 
Please review the photos and feel free to ask any questions you may have.  
 
It will be carefully packed.
