Anno 2027... anything left to be researched about Omega watches ?

A question I get from time to time:
Anno 2025... is there anything left to be researched about Omega watches ?
☕
The answer is obvious when You're on a forum where Omega fans are asking "How many Straight Writing Speedmaster were produced?"
☕
There's even a topic #AskOmega
☕
And some of us are left with some burning questions in their pockets...
Let me give an example ... and as a GOM - Grumpy Old Man a final (boring) post here on the forum...
1975 Apollo-Soyuz Test Project saw a record of 10 Omega Speedmaster chronographs simultaneously flown-in-space!
AFAIK, what the NASA photos clearly show (and Stafford made sure to photograph all watches in detail), the three NASA astronauts each wore two 321 versions (4X 105.012 + 2X 145.012) while the two cosmonauts each wore two 861 versions (4X 145.022).
Moreover, it was always mentioned that cosmonaut Alexei Leonov carried a third watch onboard ASTP, without being specified if this was an Omega Speedmaster or an Omega flightmaster!?
I'm the first to realise this is nerdy/esotric research but I wonder if the Preference Kit contents paperwork listed this 3rd watch in detail so we finally get the answer which was that (elusive) 11th wrist watcfh worn 50 years ago !

Edit: 1975 ASTP 11 Omega watches in space
Contrary to what I have been told by Omega Heritage in 2015 (40 years ASTP)
More & more echoes/messages reaching me stating that Alexei Leonov's third watch was an Omega flightmaster pilot watch.
It looks like this flightmaster was sold at auction by Sotheby's in 1996... Anyone has a reference (lot number 189 : price achieved)?
.

I was always surprised that the watch does not have any engraving. Artyukhin's flightmaster does.

Well, there surely is... and hopefully before the Speedmaster will celebrate its 70th Anniversary !

Could you please link me to this?

There's so much more... really a pitty it took 70 years before research by amateur-sleuths was taken seriously !

Actually, during the longer J-missions (Apollo 15, 16 & 17) the ALSEP carried a HFE to be deployed onto the lunar surface by drilling two holes for the heat probes. During Apollo 16 this experiment got wordlwide attention as on lunar EVA-1 Commander John Young tripped over the cable !
In fact, also on Apollo 15, during lunar EVA-1, Commander David Scott had also tripped over one of the cables to the probe and moved the electrical box from its position. It had to be realigned on the next EVA.
The cable attachments were strengthened for the Apollo 17 instruments so that even the excessive
force of tripping over the cable would not pull it loose.
Of course the ALSEP HFE is another experiment than the one Omega aficionados have been discussing, which is the Heat Flow and Convection Demonstration, only carried on A14 & A17:
Interestingly, the manipulation and flow pattern data gathering was recorded by the 16-mm DAC.
That's how we can see Apollo 14 CMP Stuart Roosa wearing his Rolex GMT-master 1675 passing in the frames and we can spot the bezelless Omega Speedmaster chronograph on both experiment setups.

Well....... sorry but this still looms over the Omega community.

Are we going to solve this in 2026?

On Apollo 14, the HFCD Experiment was done by Stuart Roosa on the way back-to-Earth
On Apollo 17, the HFCD Experiment was done by Ron Evans just before entering lunar orbit with a stabilized CSM-LM configuration... never heard of a HFCD experiment onboard a Lunar lander !

You're mentioning the HFE part of ALSEP, to be set-up on the lunar surface by the Moonwalkers, which was flown on the J-missions (A15, A16 and A17).
But as far as I know, there wasn't a timing device involved in that experiment, which was an electronics setup measuring the variations in heat transfer in the upper regolith subsurface of the Moon in order to check if there was a correlation with surface radioactivity.
NASA photo AS-15-92-12407 shows the HFE experiment during Apollo 15, note both probes held by the Moonwalker and the rack with drills in the foreground... no Speedmaster involved !

The HFCD Experiment was a small set-up onboard the CSM, with a 16 mm Data Acquisition Camera and a bezelless Omega Speedmaster 145.022-69 chronograph attached to record the 15 minutes of heat flow in fluid dynamics by using Krytox oil.
During A14, performed by CMP Stuart Roosa while returning to Earth, during A17, performed by CMP Ronald Evans just before entering lunar orbit with a stabilized CSM-LM spacecraft configuration.
After the Apollo 17 mission, Ron Evans could choose a memento and he kept the bezelless Speedmaster, which was later sold at the "Omega Speedmaster 50" auction by Christie's New York:
145.022-69 with "FLOWN IN CSM TO THE MOON" scratched in the caseback
861 movement ( 30.593.275 )
.

Changed the title in 2027 as it will be the " 70th anniversary of the Speedmaster chronograph "
(and still we don't know everything 🤨 )
.
SWFG Space Watches Facebook Group is working on a series of infographics...
Talking about updating information:
1. Which Speedmaster version did John Young wear during STS-1 (April 1981)?
(Looks like a reserved NASA-issued Speedmaster with two push buttons 🧐)
.
2. Ten Speedmaster chronographs during ASTP (July 1975), which 861 versions for the Soviets?
(145.022-69 or 145.022-71 or 145.022-74)
...

Or straight writing.
