Alright, it is now available to ship! And all inserts will have an adhesive back for easy installation. Check out my website at radialproject.com I did this for myself, but wanted to offer it back to the community as well (and to recoup some of the costs!) enjoy, I'm happy to answer any questions.
Among others, NASA requested a redesign of the chronograph subdials to improve readability, so Omega initiated the "Alaska" project to create the "perfect" astronaut watch...
By September 10, 1972 the Research & Development department of Omega, under SSiH (Société Suisse pour l’Industrie Horlogère), had redrawn the design for a new clearer dial to be used by astronauts and the Speedmaster radial dial design was born.
- I think the redesign was about improved readability in general. So an improved contrast and non reflecting dial was the most important. that's why all black radials are way darker than the regular production dials.
- About the radial design one can see a clear line of evolution (radial Seamaster 321 already existed in 1967-68)
White dial ALASKA II (more or less same font as Seamaster )
ALASKA III earliest dials have same font as ALASKA II
ALASKA III issued one have a different font
the 1978 radial dial Speedmaster chronographs delivered to NASA came with a Tachymètre bezel with no use in space ?
It may have been useful if the capsule missed the expected landing zone.
The NASA Chopping Tool would have had little or no use in space but it was a standard issue survival tool.
If a person wanted to put a radial bezel on a NEW321…
If I understand correctly, in addition to purchasing this bezel insert, with the NEW321 having a ceramic bezel I’d want to get a second bezel itself. I wonder if (A) the NEW321 bezel part is available without the ceramic insert, or (B) if another model bezel can be fitted to the NEW321
[...] However, one of the requested changes was the replacement of the Tachymètre bezel by a clear "60 minutes" bezel [...] Speedmaster in June & July 1971.
Hi OF,
this year we have already the 50th Anniversary of that event - perfect timing to fit the bezel to my Alaska Project
Today the upgrade was done and I am very very happy with the result 😀
Still working on the complete detailed Omega Speedmaster puzzle for NASA.
(By June 1965 NASA had 30 astronauts on active flight status and only 20 Omega Speedmaster chronographs).
Between April 1965 and May 1968, 97 Omega Speedmaster were delivered in 4 batches...
Early days 3 survived the December 1964-April 1965 NASA testing procedures. Two of these were used onboard Gemini III by astronauts Grissom & Young, their 2nd watch was an Accutron Astronaut).
Gemini III backup: Thomas Stafford also received a NASA-issued Speedmaster as Walter Schirra already owned his personal Speedmaster CK2998 (at that moment without a bezel).
First official batch was delivered on April 23, 1965 ( 17 each 105.003).
Second official batch was only delivered in May 1966 !
I have no exact dates for the 1967 & 1968 batches deliveries 🙁
Is there any undated information on the "unassigned" late 321 (145.012-68) models? Used on Apollo 11 and 14, Skylab 2 and 4 and ASTP (two by Stafford)
But S/N 74 and 78 I have no issue data. Then 83-97 I have a note "not assigned", which doesn't make sense. They went on to buy more from Omega but (cheap NASA) never issued 15 watches? (Also, S/N 92 was auctioned in 2022 so SOMEONE got them).
Mainly for curiosity, and perhaps some went back to Omega for modifications or something as part of the testing process... I don't know!
