Seamaster 300 233.90.41.21.03.001 in blue
This version swaps black for a deep blue on both the dial and the bezel. The case is silver tone in our photos, and the numerals, hour markers and hands are a warm beige that stands out on the blue. The words Seamaster 300 sit in small script above the 6, and there is no date to break up the dial.
