My High School Graduation Present
Astronaut "Mark I (AKA Deep Sea 666 feet World Time Zone)
All MK1 Astronauts used the 214 movement with adjustment from the rear of the case.
All MK2 Astronauts used the 218 movement and had twin crowns.
Ergo, subject cannot be a MK1.
Edit- Why does the "Astronaut MK1" newspaper ad only say " stainless steel, water resistant" in the description, when the watch has day/date complication and 666 feet water resist?
All other correct descriptions in that 1971 full page ad have the complications and depth resistance noted in their descriptions.

In reply to Blow up of World Timer by bobbee
There are some subtle differences with this ad and the subject watch: one being that the 'DEEP SEA 666 FEET' is not shown on the watch in the ad; another being the day/date background is white - subj is more in line with the center dial color (or perhaps aged over time); another being the outer lines/ticks between the 5min markers on the subj watch are red - the ones in the ad appear to be another color other than red; also the triangle marker under Greenwich is red in subj watch - not red in ad.
Is it possible this advertised World Timer was not designed as a Deep Sea, and that there are variations of the World Timer different from this ad that may include Deep Sea versions?
Really nice watch BTW!
I take back to the my previous opinion "Astronaut MK I" actually looks completely different

here is "Deep Sea World Timer" http://www.boomertime.com/solditems/A3093/A3093.htm
I would agree with this ID

well it sounds like you guys have your work cut out for you, in correctly identifying my watch.
just to let bobby know i have own the watch sence it was new and it has never been altered.
thank guys
bob
Good find on the watch Jaroslav.
I can see it is mint Bob, and well done to you for keeping it in such good condition, and such a great heirloom.
Bob.
Ken, I think you may be right about the date/day wheels being discoloured with age. The whole photo is a little "dark" too.
Here is another catalogue pic with the same image (no.4) being used, still a little fuzzy! In it you can at least see the red markers in between the hour markers, that just leaves the "Deep Sea 666" missing still. Same ref. no., 21454.

Here is a better one of the first "World Timer" catalogue pic.
So we have 'World Timer" advert with a tan colored center not marked Deep Sea and a "MK1" advert with a dark center dial marked Deep Sea
I'm sticking with MK1 - as the advert originally presented suggests.
i have burst Ken's bouble
the iner dial has always been grey not brown
oh something that might make a diffrence is that this watch would have come from europe
my uncel bought it in the azors islands
did they ever make hibreads?
