Chia Lun wears a Seiko 6159 Hi-Beat Professional Diver

Golgo 13: Assignment Kowloon (1977) is a live-action adaptation of Takao Saito's long-running manga, directed by Yukio Noda for Toei and shot in Hong Kong. Sonny Chiba plays Duke Togo, the assassin known as Golgo 13, and Chia Lun plays the Hong Kong detective chasing him through Kowloon.

On the detective's wrist, visible in a rooftop confrontation, is a steel diver's watch on a bracelet. The only identification of it comes from a user-submitted watch-spotting site that calls it a Seiko 6159 Hi-Beat Professional Diver, the 300-meter hi-beat diver Seiko launched in 1968, though the site files it under a different character's name and shows no clear frame of the dial. A large steel Seiko diver would fit a 1977 Toei production, but the specific reference is not confirmed.
