Picked this one up yesterday at a flea market. Stainless steel with unusual day/date at 4 position. Face market T and S on either side of / under the 6 marker. Inside of caseback marked "T-9258 Taiwan" Caseback dated N5, no date code on movement that I can see.
Band is a Maruman 18-8 SS bracelet - not original. Polished up the crystal and cleaned the case after replacing the cheap replacement band that came on it. Been wearing it a little over 24 hrs and it's within 3 seconds of perfect. Date quicksets by pulling out crown all the way and pushing back in.
Only one like it on site was uploaded by Geoff in 2013. After 5 years, it still resides in the unknown section
EDIT: 03/02/19 Inserted an ad dated Dec. 1, 1974. It's the watch (with maroon instead of gray dial)....but no name given.
