The Apple Watch uses your age, gender, height and weight, in addition to the GPS in your iPhone and data from its own built-in sensors, to calculate both your resting calories and ones you burn during exercise.
By the way, I can already tell from your posted screenshots that your Apple Watch is, in fact, calculating your resting calories incorrectly. Your BMR is something around 1562 per the formula and the Health App information you posted above. Your posted workout shows resting calories of 25 for a workout of 14:51 length.
