the watch was not good from the date of receiving, first thing was the clasp in the watch remain open even we try to close, second thing the clasp in the band(belt) .The band buckle(clasp) opens without notice when the watch is in the arm, forcing me to intervene each time, but any time, in case of movement of the arm it opens, risk to fall down the watch at the ground .
The third main problem is: the watch works up to 20 hours after each winding (20 to 30 daily winding) each time as mentioned in the users manual.
According to the standard on mechanical watches: a daily winding can keep the watch working up 26 to 28 hours, in our case it's only 20 to  22 hours.
So my conclusion was: I received a watch with full shows problems from the first day of use.
