Wow, what a treat today! SpeedyPhill Thank you!

I hope this thread continues, it is a pleasure to learn more on the space theme. Here's Pogue collectors guide

I am after 1974 specimen of 6139-6002, let me know if any of you has one and is willing to part with.

New information ssys Pogue's watch was probably the 6139-6005.. there is some debate so make sure you are decided yourself before buying one if you want the exact watch. Otherwise they are the same.

There's no doubt of that - Pogue's was a US market watch (identified by saying only SEIKO AUTOMATIC not SEIKO CHRONOGRAPH AUTOMATIC), so it was a 6139-6005.

Thank you for illuminating me. Indeed it says Seiko Automatic on Pogue's actual watch

If I may ask a "stupid" question: the crown is only for the internal bezel operation? It does not hand wind?

Correct. You must wear/move the watch to wind.

Winding the crown only moves the bezel.

Another feature of the crown is by pushing it in once or twice you change the day date.

The crown is for the interior bezel and for setting the time and (by pressing in) day/date, but it doesn't hand wind. The 6139 movement is auto only, whereas the later 6138 movement can be both hand wound and automatically...

I loved David Williams' (canadian astronaut) Talking Watches episode.

So is there still a question as to whether a self winding movement will operate in weightlessness?

I guess not. The rotor does not rely only on gravity in its movement. It has mass and whereas inertia. If the watch itself experiences changes in motion i.e. acceleration, the rotor will accelerate and consequently rotate winding up the watch. The experimental proof is the existence of Pogue’s Seiko. The only thing the astronaut has to do is move around, at least his/her arm.

High school physics would tell you the answer...inertia...

Actually we learned of inertia in grade school. Some apparently forget such things. Inertia is something you can observe in daily life without it being explained to you, it becomes common sense.

Well, it turns out Gerald Carr's automatic chronograph wasn't a Datron but a 1970 Movado Datachron, gifted to him by Gen. Thomas Stafford !

That Fortis is breathtaking. Beautiful. I have a Sinn 156 (non-military) with the L 5100. Great movement. The 156 is nice but I wish it was more substantial and had a bracelet. Maybe I'll go looking for some cases and a dial and build a franken.
