Slava 114ChN. Crown in : movement running.
I’ve been collecting Hamilton Electrics for the last 10 years and I’ve colleagues who’ve been collecting them for 25+ years but none of us have come across the Slava 114ChN before April 2011!
This watch, produced by the Second Moscow Watch Factory in the early 1960s, seems to exist with one of two movements. One type has a movement similar to the Epperlein 100 Prototype while the other seems to have a copy of the Hamilton 500 movement. This page compares, in detail, this second type of 114ChN movement with the Hamilton Cal. 500 and describes how I managed to get my very rare example up-and-running. But for a high level view of the Epperlein 100, Epperlein 100 Prototype, Hamilton 500 and Slava 114ChN, plus a very interesting video clip from the Second Moscow Watch Factory, be sure to visit the Slava page.
First, the watch as received from a Russian seller in April 2011:

Next, the individual parts compared with those from a Hamilton 500; Slava on the left, Hamilton of the right. Slava seem to have done a very good job of reverse engineering the Hamilton 500; and the gilt plating of all parts is a nice touch.

- Wheel Sets. Same number of teeth but Slava teeth are bigger and therefore wheels are slightly bigger.
And on to the repair. Two main problems: the coil was open circuit and the balance staff had a broken pivot. The goal is use as many original Russian parts as possible; I’d rather keep this rare watch as a non-runner but still be 100% Slava.
- The coil had come away from its brass mounting on one side, breaking its electrical connection. It was re-attached with a little super glue; they original used an Araldite type epoxy.
- To restore the circuit, I use high quality 50% silver conductive paint; success rate is about 60%. It will only succeed if the break is visible and you can see exposed copper metal rather than varnished copper wire. In the case of this balance, it was at both ends of the coil where the break in the circuit was found; the main coil windings were intact.
- Having fixed the coil, this crack across the balance was found.
- Crack now repaired and the two balance staffs; Slava on left with broken pivot and Hamilton 500 on right as a potential replacement. Both staffs have the same overall length and most of the other dimensions are close.
- The small thing above the two staffs is the roller table from one of them. The purple indexing jewel impulses a tooth on the index wheel with each swing of the balance.
- Having assembled the Slava balance with the complete Hamilton staff (including roller table), it was found that the index jewel on the roller table jammed with the index wheel teeth. The position of this jewel must be slightly different between the Slava roller table and the Hamilton one :(.
- In the end, a Hamilton 500 staff was used in conjuction with the original Slava roller table. The latter had to be reamed out a little to fit the slightly larger diameter Hamilton staff. For good time keeping, the Slava hairspring was found to be necessary.
The restored watch, looking good and running well. Some have even suggested that this gold coloured 114ChN movement is more attractive than the original Hamilton 500 from which it is copied… I couldn’t possibly comment on that!
