Official Seiko custom cases - Dentsu Anniversary

I recently acquired a Seiko pocket watch that was produced for the 70th Anniversary of the Japanese Dentsu Ad agency in 1971.



Dentsu is an international advertising and PR agency that was founded in Japan in 1901. They have worked with Seiko on numerous campaigns over the years and were involved in early Japanese commercials. It is quite possible that they may have helped produce Japan's first TV commercial that was created by Seikosha https://www.facebook.com/video.php?v=10153200735565193

Dentsu continues to work with Seiko and was responsible for the recent successful Tokyo Marathon campaigns.



In 1973 Dentsu became the world largest advertising agency and today is still number five globally, the market leader in Japan and many other countries.

In 1971 to commemorate the 70th Anniversary of the company Dentsu had a pocket watch created and I believe this was distributed to staff and potentially key customers. I am not sure of the number of units produced but these seem to come up for sale quite often in Japan auctions.

The watch features an electronic 37A movement and a silver 885 case and chain clasp with the case number of 37-3000.




It has a unique dial and case design that was obviously only used on this model as the back states Dentsu Ad.




I am not aware of any other model that was produced by Seiko specifically for a private commission.

We have seen numerous models featuring company engraving or logos applied to the dials of regular models such as seen with the ScubaPro models, but I do not know of any other instance of a totally unique model being produced for non-sale.

Does anyone now of another unique model that was specifically manufactured for a customer and not sold publicly.
