Couldn't load pickup availability
This is a superb Citizen Cosmotron from 1973 that screams 70s in its design on that dial which is epic! Recently featured this watch on a rebuild video on my channel. The new owner can see me work on the inner workings of their watch!
The Cosmotron came in many types but this one, the 7801 has a great feature, the flyback second hand. A useful complication for accurate time setting and to use as a minute timer stopwatch perhaps? I have never seen this feature on a 3 hander watch other than on chronographs. Personally think it should be brought back as it offers another useful complication on a watch.
This model has been serviced by myself and is running very well on a new battery. The hybrid balance movement keeps it accurate and reliable whist still presenting in a mainly mechanical watch. it has a new caseback gasket, crown gasket and new glass & battery.
Case and bracelet have been thoroughly cleaned ultrasonically and then the case has been lightly polished to bring back the shine.
As its a vintage watch I would not recommend bathing or swimming with this piece so please take care of it.
The dial is amazing with vertical striping with a light blue center fading to dark at the applied indices.
Watch is all original including the genuine new old stock Citizen replacement crystal>
Bracelet fits my 7" wrist with one hole on the clasp ladder left. Bracelet extenders are available in this store if you feel you need more to size.

Let customers speak for us
from 28 reviewsI love the 70's and I love this watch, case shape and dressy white dial. Delivered with a nice Croc. embossed leather strap and protective film on the spotless dial glass. I am very happy that this is now my watch, it's clearly a keeper.

I love my new Seiko, judging from your Web pictures and the description I knew something special was to be sent to me and oh my what a dial!, it looks like nothing I have seen before, like brown or golden colors on a bark structure, it plays with the light give all these colors.
Bracelet is beautiful smooth with its small links. The whole watch is simply a winner and I am so happy to be the owner :-)

Tshirt is top quality. Will return for another soon.

Wonder watch

Quality timepiece

A great watch and looks brilliant and all working as it should.

I've been watching Mike's YouTube videos for around 18 months which sparked my interest in vintage watches. This is my first vintage watch and I love it. The condition is fantastic and looks fantastic on my wrist. My wife has now put it away for my birthday next month. Can't wait to be a year older ! Thanks Mike

A lovely time piece, absolutely stunning and quick delivery, very well packed

The T-shirt was perfect and love your stuff on YouTube!

Ultimately, there's not much to say.
The watch matches the description exactly and is in perfect condition.
I could have bought it directly from the manufacturer, but now I have a piece of the canal that I love to watch so much to calm down after a long day of work.
Great memory.
All the best, Mike!!!
You are a great person.
