Deciding to quit based on losses or wins suggests that you're playing stakes too high for your bankroll. And it doesn't take into account fatigue or what's going on in your life -- two factors the illustrious Mr. SInger would agree are important.
So yes, a wristwatch should be used. And the idea is far from stupid.
