The Pyramid 7000 110V replaces the Lathem Sonachron, Lathem DWA and DWA-S workshift timers.

Adding these features: 
Forward and Reverse buttons for dramatically easier schedule setting and changes
Longer lasting internal battery - no need to replace it every 4 years, a common nightmare that the Sonachron had
Variable duration rings, from 1/2 second to 59 seconds  AKA 1 second ring for a "two minute warning"
200 Ring times PER DAY (15x more than the Sonachron had), shared across 7 days
Very easy set-up, Secure locking metal case - instead of a passcode
Run up to 200 digital or analog clocks - or up to 8 Pyramid analog (dial face) clocks
Run as a master clock along with bells, or as a workshift timer alone, or as master clock alone.
