Jay,
If you will only use the chrono. occasionally, the watch is fine and beautifully made. If you will depend on it many times a day for billable hours, this is not the watch for you, as the chrono hours and minutes are too often unreadable. Sadly, Patek has never made any chrono. that is well-designed for this purpose.
I had a similar desire to own this watch, but gave it up because of the unreadability of the chrono. AP and VC make more profession-friendly chronos.
