It sports a black dial, which contrasts nicely with its visibly raised luminous hour markers & hands. It also features a diagonally-placed screw-down crown & a sapphire glass crystal.
Collectors are particularly drawn towards the size of its case at 44mm x 50mm, reminiscent of the brutalist era!

GOOD-TO-KNOW: The SEIKO Professional Diver 300m succeeds the SEIKO 62mas Diver, but both run on the same caliber 6159A 10-vibration high-beat movement. It's also interesting to note that the same movement is installed in Grand SEIKOs.
GOOD-TO-KNOW: The SEIKO Professional Diver 300m was worn by adventurer Naomi Uemura, known particularly for his solo exploits, when he summited Mount Everest in 1970.
