Why don't you run a "real-life" test by actually wearing your Sub vigorously every day as a Rolex is intended to be used. No full winds, just wear 8-12 hours/day and report +- gains once per week based on a source such as Time.Gov for a consistent/precise base reference. Do this for a few months, benefit to you is getting to wear your watch, think of that! I fully realize the practicality of such a test probably doesn't appeal to some following this thread, but it will to those who actually wear a 32xx movement Rolex watch every day.
