Today, we're going to take a look at a watch which is both very good, and very good proof that a little bit of iteration can make a huge difference: The 2021 Refresh of the Omega Seamaster 300 (Ref. 234.30.41.21.01.001). Thanks to Lewis Jewelers in Ann Arbor, Michigan (https://www.lewisjewelers.com/) for helping me pick one of these guys up for review.
