the watch is not holding time properly it is running slow(although it has a good loud tick) Sat/Sun 18th and 19th between 11.39 and 01.34 it lost 8 mins then Sun/Mon 19th and 20th it read 06.30 when actual time was 8.45 all GMT. As it is I cant be sure of the indicated time and therfore have no confidence in the time shown on the watch. Can you please change the watch.
