Just wondering your thoughts on this. Besides high precision clocks that are designed to keep accurate time in a variety of conditions, do solid plates really make that much of a difference in the integrity of a clock movement? Take for instance an earlier Seth Thomas Sonora with cut out plates - both movements did not have solid rear plates until later on. I presume that this was more for show, because the front plates of both movements were still cut out. Solid plates especially look nice when they're lacquered and shiny, but besides looking more expensive I don't see any other benefits. What is your experience/thoughts on this?
