I have owned this watch for about 10 years now and love it.
the past few years the chronograph buttons (on the left side of the watch) were not working well rendering the chronograph and count down timer functions unusable.

repairing a chronographs is expensive and watch makers usually charge several hundred dollars which is not a feasible fee for a watch of this value so i decided to open it up my self and clean it up and that did the trick.. its working like new!

enjoy the watch!
