So, finding myself a bit of a Citizen fan as of late, after a few great purchases off the Bay, i was feeling gutsy and decided to try to acquire a Spacemaster. This is what i managed to find:
First impressions were mixed as the watch was advertised as working but with a dead battery, and after a battery change it was still dead, didn't react to the specific reset procedure that Citizen provides. On the other hand the watch feels barely used, it came with the original Green Citizen strap that seemed unused as well, so that led me to believe the movement was indeed working.
I decided to just leave it with the new battery installed for a good few hours and lo and behold, it came alive. The procedure to align the hands and the date wheel is somewhat involving, and quite hard on the fingers. Maybe the pushers on these watches were easier to push when new, but they are quite un-ergonomical due to being round, and takes quite a bit of force to depress. After aligning it was time for a manual receive, so i set the watch up for that and placed it close to my Junghans RC 2 table clock which i know receives a signal.
The 8410 movement is quite nice, it features a signal strength indicator, and as soon as a stable signal is detected the small red LED flashes satisfyingly.
The watch has alarm feature as well, i recommend everyone contemplating getting one of these watches to read the instruction PDF, available from Citizen.
All in all, i'm happy with my new watch, it's in great condition and working well. I especially like the caseback engraving which is typical of watches from the era sold in Germany, or so i'm told.
Feel free to chime in with any info you guys might have, such as what the TA means in the model name. I doubt the watch is titanium, it feels much too heavy for that. Possibly the caseback. Info on the watch is scarce, mostly german watch forums.
