Watt is a lunar crater that is located in the southeastern part of the Moon. The northwestern third of the crater rim has been completely overlaid by the same-sized Steinheil crater, leaving much of the interior floor covered with the outer rampart of ejecta from the later formation. The remainder of the rim of Watt crater is somewhat jagged in appearance, with an inward bulge along the southeast rim and a pair of small outward projections to the northeast. The rim is otherwise relatively sharply-defined, with only a minor amount of wear.
Nearby craters of note include Biela to the south-southeast, Rosenberger to the southwest, and the Janssen walled-plain to the northwest past Steinheil. This crater should not be confused with the small Watts crater located to the north, just past the lunar equator.

By convention these features are identified on lunar maps by placing the letter on the side of the crater mid-point that is closest to Watt crater.
