Seiko produced Stellaris for Sears, Roebuck, and Company as the in-house brand for Sears – and this sharp late 1960’s Stellaris, with a Hamazawa 5020A manual wind movement is no different. 

 

Hamazawa Ltd – founded in 1954 – had and unofficial relationship with Seiko.  In the 1970s, Hamazawa took out several joint patents with Epson (one of the three core companies of Seiko Group in contemporary times) on non-watch related items.  

 

It appeared to have sold a lot of movements to various Japanese and foreign watch companies, and in 1983 Hamazawa merged with two other companies, one of which was a major watch case supplier for Seiko-Epson.  Subsequently, in 1986, this company was taken over by Seiko.


That said, we are getting ahead of ourselves – in the 1960’s, Hamazawa released the 5000 family of movements, both automatic and manual wind.  Of note, the self-winding mechanism partially uses the Seiko Magic Level System. 

 

Back when this watch was made, Hamazawa was most likely somewhat independent; however, the mechanism on the 50xx movements (like the one here) would have required a license agreement with Seiko who held the patent at that time.  The movements were sold widely overseas and may be found in US brands including Sears and Benrus, and the British brand Astral.

 

This Stellaris comes with two NATO straps, Pelican travel case, and springbar tool.
