1955 Helbros 10K 21 Jewel P61 "germany" watch

1955 Germany made Helbros watch 21 Jewel PUW61 movement (top of the line!)
10K gold filled case, interesting design
crystal is magnifying and concave so at a sharp angle the time can still be seen (like a distorted magnifying lens)
Freshly cleaned and oiled, running like a chronometer (timed with my citizen eco-drive)
nice 1/20 gold band (expansion) fits good

"the 60/61 was regarded as the only German movement with chronometer capability"
