Type A Power Station Station Master Clock
Type E Power Station Master Clock
One of only two surviving examples of the Type E Master Clock.
Type B Power Station Master Clock
An extremely rare example of a power station master clock, this Type B model created by Henry Warren in the early 20th century. It was used to precisely regulate the frequency of the power station's generators- which Warren's newly invented, electric synchronous clock movements relied on to keep the correct time. This is a particularly lovely specimen, with a shiny nickel-plated face and a wood case that is still in perfect condition. In this collection there is also a later Model E version of Warren's master clocks.
