I would have to rank the Cady Automatic Hand Micrometer as one of the most beautiful and well made tools I own. The E.J. Cady company is still in business, making this exact model which looks like it has not changed in design or construction since the 1950’s. It would not be out of place on the dashboard of a Bentley.
Like most people, I have a number of dial micrometers, or dial thickness gauges as they are sometimes called. A deep throat Calati is perfect for measuring in the center of large sheets of paper. A super accurate Ames #2 (.0001″) with a 6oz. weight on top is great for obtaining standardized results with slightly compressible material, like leather. A portable, hand held Mitutoyo is small and lightweight, perfect for taking on the road.
Since I only use micrometers these a couple of times a year, the batteries in the digital ones always seemed to be dead. The digital versions are handy, though, if you use them a lot, or need to easily convert between English and Metric systems. The mechanically geared hand on the dial face has a definite nostalgic attraction for me, like the VU meters on a stereo amplifier.
