This is a special quartz wall clock. It is a so called Stop2go clock. The second hand stops at 12 for 2 seconds then the minute hand moves 1 minute further. Exactly like the clocks on the Swiss railway stations. The diameter is 250mm and thickness is 42mm. The case is made of aluminium with a mineral glass. You can download an APP from Mondaine in your smart phone to control and set this clock. It only need 1 AA battery for running.
