The mystery has been solved. Those who collect flip clocks that have appeared in the movies or on TV now can put a model number to an obscure TV flip clock that appeared on "Fringe" in 2011.

Fringe is a TV series created by J. J. Abrams, Alex Kurtzman, and Roberto Orci that premiered on September 9, 2008, and lasted 5 seasons, concluding on January 18, 2013 after 100 episodes. The series revolves around Olivia Dunham (Anna Torv), Peter Bishop (Joshua Jackson), and Walter Bishop (John Noble), who are part of the "Fringe Division" of the Federal Bureau of Investigation. The trio and their cohorts investigate and seek to find the underlying cause of an endless string of strange to downright disgusting mysterious happenings, which are eventually discovered to be related to a parallel universe. Interestingly, the parallel version of Walter Bishop comes to be known as "Walternate."

In episode 15 of season 3 entitled "Subject 13" of Fringe, which aired February 25, 2011, at 30 mins 45 seconds into the show, if you don't blink, you can spot a period flip clock. The episode, "Subject 13" is a flashback to 1985 with scenes set in both the prime and the parallel universe. In this episode "Walternate" in the parallel universe struggles to deal with the kidnapping of his son, Peter. The flip clock appears for only 16 seconds on the night stand beside the alternate Elizabeth Bishop's side of the bed.

Your author spied this clock when bingeing on this series in 2014. For years queries went out across the internet trying to determine: 1. If this was indeed a flip clock, and 2. If so, what was the make and model. Then, on February 4, 2017, while searching on eBay simply for "Flip Clock" there appeared what is certainly the Fringe Flip Clock.

Drum roll please.

The flip clock that appeared in the television series Fringe, is the Baycrest Model HB-23, distributed by The Hudson's Bay Company, Canada.

This makes sense as the filming of the series moved to Canada for Seasons 2-5. The props department obviously picked up an available period flip clock locally. Which explains why a flip clock that wasn't even sold in the US appears in this scene.

So there you have it, collectors of Movie and TV flip clocks, the "Fringe Flip Clock," the Baycrest Model HB-23.
