The brand of golf ball found by James Bond (Sean Connery) during a golf match with Goldfinger (Gert Fröbe) in Goldfinger. Goldfinger also plays a Slazenger, but it’s a Slazenger 1.

When his adversary decides to make up for a bad lie by having his caddy, Oddjob (Harold Sakata), illegally drop a new ball on the main fairway, Bond decides to use the Slazenger 7 in a counter-cheating ploy.

Pulling his Penfold Hearts and Goldfinger’s Slazenger 1 from the cup, Bond substitutes the Slazenger 7 for the Slazenger 1, which Goldfinger promptly bangs onto the next fairway. Losing the final hole on purpose by blowing his last putt, Bond goes to the cup and announces that poor Goldfinger has been playing the wrong ball. Since strict rules of golf are in force, Bond’s opponent must lose both the hole and the match.
