The chrono function is also hardly useful to me, unless i wanna time my runs or dive. But then again, under such circumstances i would rather use a digital watch or a proper dive watch. Or i could use the chrono to time my half boiled eggs.

On a more serious note, i personally would not look for a mechanical chrono watch. Firstly, due to under usage for me. Secondly, the selling price will also be higher. Thirdly, the service costs will definitely be much higher too. And if i want a more complicated looking watch, i'd go for small seconds/PR indicator/moon phase/calender functions.
