Did we save the best for last? Maybe, with this absolutely gorgeous SRPF77 “Manta Ray” Diver. Just like the SRPE33 above, this watch face positively glows, with a rich, dark, gradated blue, graced by several manta rays in the foreground. The blue of the dial is meant to evoke variations in sunlight as it penetrates the ocean’s surface, and we daresay it succeeds.
Other aesthetic features include a black ceramic unidirectional bezel, a magnified day/date calendar, and LumiBrite hands and markers.
Inside the watch, the 24-jewel automatic movement beats at a frequency of 21,000 vibrations per hour, with a power reserve of around 41 hours.
Rounding out this beauty, you’ll find a screwdown crown and caseback, anti-reflective sapphire crystal, and deep blue silicone strap to match the blue of the watch face. And at around $430, we know we’re sold.
