Studio 60 countdown clock

I don’t want to hijack the main thread about tonight’s episode, so I’m starting this separate thread for my much narrower question:

Where can I find a countdown timer like the one on the back wall in the studio?

I’d appreciate any leads! Thanks.

A quick look at googles shows this: Welcome to BRG Precision Products - The Leader in Custom Digital Time Zone Displays, Event Timers, Safety Timers, Synchronized Clocks Systems, Carillons, Electronic Bell Systems, Digital Clocks, Analog Clocks, PoE Clocks, Ethernet Clocks, Take-A-Number Queue Management System and More

I was amused that the website that RealityChuck linked to mentioned that their “long duration timers have been configured to maintain the correct countdown, even when power is interrupted for an extended time” since that answers a question posed by Matthew Perry’s character during the show.

BTW, I like the show, but the countdown clock is a lame gimmick.

There are people around here in The Biz. Maybe it’s a real thing. I could see it being quite useful when putting a show together. Anyone?

Thanks, RealityChuck!
