I saw my flight was showing a diversion. I called the [Chief Dispatcher] to see why I was not notified of such an event. At that time I was told a window fell off. Flight was already back on the ground. Upon the flight arriving at the gate Captain explained the situation.On takeoff roll the Captain's window slid open. The captain transferred control to first officer who continued the takeoff roll; Captain tried to close the window but window came off tracks and landed in the Captains lap. The flight advised tower of the issue; remained in the pattern; and returned to land.
During takeoff roll; the Captain's window came open. Captain transferred aircraft control to First Officer and continued takeoff. Captain was unable to close the window because the window was completely off the track. Captain secured window off to the side of Captain's seat. First Officer leveled off at 8000 ft. Communicated with ATC to return for landing. Entered data to receive landing data. No overweight landing. Notified Flight Attendants of situation and the need to return due to inability to pressurize aircraft. Landed and taxied to the gate uneventfully. Notified Dispatch and Chief Pilot on Call. Updated passengers upon arrival at gate.
B737 flight crew and Dispatcher reported the Captain's sliding window had come open during the takeoff roll; then came completely off the track. The flight returned to the departure airport.
