Full kit of parts, including double dot neon colons, pre-soldered passives and SMD ICs, tube sockets, RGB LEDs and Double Dot Neon Colons. 
433 Mhz Receiver included if you also order the matching XTERNA transmitter.



All the SMD components are pre-soldered! Only the through hole components need to be soldered.

Here is the assembled Clock, ready to mount in the included case.

A high quality 12V Power Supply is included, with a long 6ft cable. 


Optional Time Receivers (Select with the dropdown box):
1. GPS Time receiver, easy to configure, but the module needs to be within 2 metres (6 feet) of a window

2. XTERNA Time / Temperature Transmitter:



3. WiFi Time receiver. Use a smartphone to configure, sits discreetly behind the clock on a 15cm cable
