Eponym	James Watt

Watt is a lunar impact crater that is located in the southeastern part of the Moon. It was named after Scottish inventor James Watt.^[1] The northwestern third of the crater rim has been completely overlain by the same-sized Steinheil, leaving much of the interior floor covered with the outer rampart of ejecta from the latter formation. The remainder of the rim of Watt 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 walled plain Janssen to the northwest past Steinheil.
