Want to see a real astronaut's watch?

With the 1953 Airman probably the first wristwatch with a rotating 24hr bezel combined with a 24hr movement/dial, I don’t know of another watch before 1954’s GMT Master to present a 12hr movement/dial together with a rotating 24hr bezel and “GMT hand.”

I’d love it if someone (inevitably) chimed in with a little-known contrary example!

Rotating bezel:
1929 Longines Weems
1937 Rolex Zerographe
1953 Glycine Airman (24 Hrs bezel)
1954 Rolex & Blancpain diving watches ... ...

The 1959 LeCoultre 24 hours dial "astronaut watch" was based on the military-inspired Quartermaster 114 and 112 versions, aka "thin lugs" versions.
The LeCoultre Quatermaster came with a special hand-wound caliber K831/CW, 18 K VpHour, 40 hours power reserve, of course with a single full rotation per day, hence the 24 hours dial.
Quartermaster versions came in a 33,5 mm stainless steel waterproof case, with the 114 & 112 having a locking-ring caseback, while the angular profiled lugs 2405 version came with a screw-in caseback.
The bespoke version, ordered by NASA for the "Mercury 7" astronauts came with a totally different matt black dial with white painted hour and minute markers. No luminescent material was used as safety reasons prescribed any radiation was to be avoided.

A bit of an exclusive preview 😉 "" First Watch ""
65 years ago... NASA procured the very first astronaut watches!
In September 1959 the close cooperation between the NASA Space Task Group and an important wrist watch brand was fulfilled by the delivery of bespoke 24 hours dial anti-magnetic stainless steel wrist watches for the "Mercury 7" astronauts.
How and why this was accomplished can be read soon in another MoonwatchUniverse article on wrist watches in spaceflight....

Cooperation between "On-the-Dash" and Fratellowatches and MoonwatchUniverse : 65 years ago... LeCoultre "Mercury 7" astronaut watches

That's a good question, we guess LeCoultre USA... the bespoke watch was realized in only 6 months time !

NASA astronaut Walter “Wally” Schirra’s 1988 book “Schirra’s Space” revealed that the 8th LeCoultre “Mercury 7″ wrist watch went to NASA STG engineer Harold I. Johnson, a member of Flight Control Branch Training Aids, who was responsible to get the wrist watches in the first place.
Although in sink with the Zulu time zone of the wordwide NASA tracking station network, the Mercury 7 astronauts only wore the LeCoultre 24 hours dial watches, nicknamed ” the Johnson watches “, during training and PR events between September 1959 and October 1963.

65 years ago… NASA survival training
1960, between July 12 & 17, the Mercury 7 astronauts participated in the very first NASA survival training which was organised at the Stead Air Force Base in Nevada. During a week, the USAF trained the astronauts in desert survival near Carson Sink the northeastern part of the Nevada Carson desert.
By that time, LIFE magazine already had a contract with the “Mercury 7” and photographer Ralph Morse hired a small aircraft to search for the astronauts, dropping bags of flower so he could join them by surprise to take photographs.
Wrist-watch-wise interesting as the astronauts wore the bespoke 24 hours movement/dial LeCoultre wrist watches NASA had issued in September 1959. The NASA STG for project Mercury wanted a time piece with 24 hours indication as the worldwide tracking network worked with 24 hours Zulu time.
These 34mm LeCoultre “Mercury 7” astronaut watches were based upon the LeCoultre Quartermaster and 8 were delivered to NASA but only used during training & PR events up to October 1963.
Thus far three have resurfaced, with the Grissom & Glenn watches being sold at auctions!
