Microma esa 931.771 NOS with Digital hands in NOS conditions.
The watch works but the mode menu seems to be lazy sometimes (chrono mode does not works always).it's not a button problem,maybe a lazy module or something similar.
Setting time is off course possible but it's tricky.i suspect a working module with some defect here and there.
Anyway the watch is working and keeps good
time,adjusted with a professional quartz machine (+00.08/9 sec per day).
Thanks
