Not actually a clock, this is a Steampunk Thermometer that also displays Humidity. It uses a special IN-19 Nixie tube to display the '%' and degrees 0C symbols. It does also of course have twin Verdurite Emanation coils to help power it all.
Some very nice woodwork to the base, nearly an inch of solid mahogany to support the lighthouse and keep everything stable and firmly planted on the desk. Original period labels also fitted as an extra touch. And of course, it functions as a Lamp - It uses 20 high power white LED's in the top for a cool and efficient source of light, a really novel item!
