I've bought unworn Maurice Lacroix Miros Chrono Diver watch and need some help: watch is running, but chronograph doesn't response to push buttons, it does nothing. When crown is in position 0 or 1, chronograph hour and 1/10 hands are not zeroed (1st picture), when crown is set to position 2 (or 3), hands move quickly to new positions (2nd picture) and vice versa. I can't set the counters to zero according to the manual, no response to the push buttons in either crown position, no chronograph start/stop/zero function. Is that something wrong with the watch or am I missing something or the watch should be "reset" (battery removed and insert back)? For the moment I haven't got watch case opener, so haven't tried to open the watch. Is it possible, that battery is weak? The watch is ca. 1.5 years old. Thanks for advice.
