24-Hour Dial · Reading and design
How to read
The hour hand turns once a day; the minute and second hands keep their usual cycles. Use the even hour labels for hours and the 60 divisions for minutes.
Historical background
Greenwich’s Shepherd Gate Clock has displayed time publicly on a 24-hour dial since 1852.
Design and this interpretation
Morning and afternoon occupy different parts of one circle. This face uses even-numbered hours and simple marks rather than reproducing the historic Roman-numeral dial. Unlike the single-hand face, its separate minute hand gives a direct minute reading.
