Hi, I got this one as a present from a friend... so I wore it for about 4 days and went to check how precise it was... to my suprise it was still exactly like my phone time... so I installed and bought an app to measure acuracy.. and here I will post the results... the movement is an AS1538... so is this just luck or is this calibre very good ?? I get +0.4 sec and mostly 0.0 sec...
