Rover, very sweet and a very nice wrist shot. That was a very smart idea on getting a base timing. The first thing i look at before i touch a watch is to see where the regulator is set at. Almost all are set fast and so out of beat you can actually hear it. Especially in high beat watches like these. The first 67-9054 i ever bought gained 15 minutes in an hour. It ran "wide open foot to the floor" for 3 hours and locked up. I timed it off my Omega and the sweep seconds hand was passing the other. I was actually impressed with the 8110a that it could possibly run that fast. 31Here's mine. I was fortunate enough to find an all original one on eBay for a reasonable price. When I received it, it was not keeping consistent time. Somehow the beat lever had been moved considerably. Lacking the equipment to reset the beat the proper way, I started checking out photos online of 8110 movements and observed that all of them had the beat lever in the same spot. I carefully moved it to match the position in the photos. Now, it keeps very accurate time!
