Rado Voyager MK 1 25 jewel automatic this model has the 5 figure model number 11814 which means it was made between 1970-72, later models had an eight figure numbers. The movement is a Rado 2794, which is a customized ETA 2788 day/quick date.
Vintage Rado watches have the famous Anchor logo which rotates independently of the watch mechanism which is a great feature. The day date display at 6 o’clock is a feature that really appeals to me.
The name Voyager, make me wonder if the inspiration came from Star Trek? Well I would like to think so, the date certainly matches.
The ‘Voyager’ model name went on to become the entry level watch for Rado, in many shapes and reincarnations but I am happy to say this model is a high quality first generation Rado ‘Voyager’ Tonneau cased. The model is listed in this brochure from 1972, it is the middle watch of the above trio.
Rado 2894 equivalent to the ETA 2788, but customised, also has a German day wheel. 
The earlier models also have the screw on back case, later models push on. A lot of Rado automatics from this era is the use of the Seahorse logo. Rado water-resistant case backs of the era were engraved with a medallion picturing two or three seahorses with the words “Water-Sealed” beneath. And the anchor logo on the crown.
