The postman is the character who hears Bernard's wish, to avoid being late and to have more time, then he gives him the watch. His full name is never mentioned though his first name is revealed to be Ken in the episode Time's Up. He is from the firm which maintains the watches and enforces the rules for keeping them. He is summoned when his clients want him to be there and help them with any problems with their watch. However he is shown to be sometimes forgetful such as not mentioning a client getting a new watch when crossing time zones, or forgetting to set the handbrake in his van which runs away with the client's life files aboard.
