I listen for the clicks, THEN confirm with altimeter and VSI (which is usually the last one).
The only "click" that
may be audible in non EFIS type aircraft is the landing gear lever latch solenoid.
If the landing gear lever can't be raised after take off, Boeing procedures state the the gear must remain down. Flaps up on schedule. After flaps are up and lights are out, and if the takeoff configuration warning horn remains silent and if the trust levers are beyond the vertical position... landing gear lever override trigger pull... landing gear lever up and off.
