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
