I have added another member to my collection . This one is a Hamilton Electric RR Special . This one was sold as a non-runner and had no hands , Otherwise this watch is complete and original .
The RR Special case is 37mm , has a screw down back , and the watches date from the mid 60's .
The RR Specials used the 505 movement and had a micro-sdjuster on the balance cock to regulate the time more accurately . as can be seen in the last photo.
These watches came in 3 variations in the case selection . They being the models 50 , 51 , and 52 .
The 50 is all stainless steel , the 51 has a stainless steel case and back and a 10k gold filled bezel , and the 52 is all 10k gold filled . I have the 51 .
Below is a pic taken from the site , Electric Watches UK , that shows all 3 models and their variations ....and also the correct hands that came with this model .
As I stated , this watch came as a non-runner and I found 2 issues to that affect .
First , there was a tiny screw stuck to one of the case magnets under the balance wheel that hindered movement ,...and second , I had to replace the very tiny contact on the dial side that provided power from the Neg side of the battery , through the contact , to the coil on the balance via the index wheel .
After a complete service and with the replacement contact in place , this puppy took off running ....and keeping good time so far....
Finally after reassembling the watch , I found a set of blued minute and hour hands in my stash that needed a bit if reaming to fit , and also a genuine Hamilton Electric second hand , and set them to the watch .
I will wait a while and see how the watch runs and then re-lume the hands and paint the second hand red .
