- This watch face implements the original F-91W stopwatch functionality
- including counting hundredths of seconds and lap timing. There are two
- improvements compared to the functionality of the original:
- 1. When reaching 59:59 the counter does not simply jump back to zero,
- but keeps track of hours in the upper right hand corner. (Up to 24h)
- 2. Long pressing the light button toggles the led behaviour: it either
- turns on on each button press or it doesn't.

+/*
+ * STOCK STOPWATCH face
+ *
+ * The Stock Stopwatch face implements the original F-91W stopwatch
+ * functionality, including counting hundredths of seconds and lap timing.
+ *
+ * Use the ALARM button to start and stop the stopwatch.
+ * Press the LIGHT button while the stopwatch is running to view the lap time.
+ * (The stopwatch continues running in the background, indicated by a blinking colon.)
+ * Press the LIGHT button again to switch back to the running stopwatch.
+ * Press the LIGHT button when the timekeeping is stopped to reset the stopwatch.
+ *
+ * There are two improvements compared to the original F-91W:
+ * o When the stopwatch reaches 59:59, the counter does not simply jump back
+ * to zero but keeps track of hours in the upper right-hand corner
+ * (up to 24 hours).
+ * o Long-press the light button to toggle the LED behavior.
+ * It either turns on with each button press or remains off.
+ *
+ * NOTE:
+ * This watch face relies heavily on static vars in stock_stopwatch.c.
+ * The disadvantage is that you cannot use more than one instance of this
+ * watch face on your custom firmware - but then again, who would want that?
+ * The advantage is that accessing vars is more direct and faster, and we
+ * can save some precious cpu cycles. :-)
