In my example startTime[msg.sender] is the time where the watch has started, ie the user first request to the contract. Then startTime[msg.sender] + 60 minutes is 1 hour after the first request. In that case if now <= startTime[msg.sender] + 60 minutes is true, it implies that less than an hour has elapsed.

Actually, wouldn't be if (now <= startTime[msg.sender] + 60 minutes) with an less than equal to operator? So we can check as long as now is less or equal to now + 60 minutes?

This is what I have been trying to do! Let me make sure I have this right: you are mapping the msg.sender to the current block (a uint), then checking to see if the current block is more than or equal to the msg.sender's time of transaction + 60 minutes, and finally doing whatever you need to do in the if function.
