Orvin 1954 Power Reserve Automatic

Back in the 1950s when Sears Roebuck sold pretty much everything, “everything” included luxury Swiss watches, and Orvin was their exclusive brand. I was particularly excited to open this one up, as I had never serviced a movement with a power reserve indicator and I was very curious how it worked. What I found was some very clever mechanical engineering able to track & differentiate the independent rotation of both the mainspring barrel and the winding arbor. Really cool stuff. The watch doesn’t look half bad either. I ended up overplating the case, and it turned out very nicely.
