Who was the announcer during Jack Narz's "Beat the Clock"?

Gene Wood was the announcer during Jack Narz's run on Beat the Clock. Wood supplied the show's announcing voice while Narz hosted the syndicated revival that began in 1969.

Beat the Clock was a stunt-based game show in which contestants attempted to complete unusual physical challenges before a large clock ran out. Narz hosted the first three seasons of the 1969–1974 syndicated version. Wood was his announcer and became closely associated with the program's energetic introductions and contestant cues.

When Narz left the show in 1972, Wood took over as host for the remainder of the run. Nick Holenreich then served as announcer, which explains why sources may list different announcers for different parts of the same series. The question's wording specifically connects the announcer role with Narz's tenure, making Gene Wood the intended answer.

Wood later became one of television's most recognizable game-show announcers, working on programs produced by Goodson-Todman and appearing on shows such as Family Feud, Card Sharks, and The Price Is Right.
