The synchronize-your-watches scene from North Sea Hijack where Roger Moore wears Golden Tuna 7549-7009 in its 1980 movie debut, one year prior to For Your Eyes Only.
A very British movie where the Tuna's day wheel is clearly set to French...or Italian.
The bad guy, Anthony Perkins, wears this evil chronograph.
Spoiler alert: Roger Moore and Tuna are triumphant!
The entire movie is on Youtube in case someone's bored. Just look up North Sea Hijack. YaY!
