1973 Seiko GMT (Ref. 5619-7010) Blue Dial
While the World Time and Navigator Timer may be the favorite Seiko GMTs among enthusiasts and vintage watch collectors, this 5619-7010 Duo Time may be the coolest.
Featuring the same incredible 56 base as was featured in Grand Seiko and King Seiko pieces of the time, this piece was unique in that it allowed independent quick setting of the 24-hour hand. This removed the need for a rotating bezel and allowed for the watch to have all the functionality while maintaining a relatively svelte and classy design.
These pieces were only in production for 2 years, from 1972 to 1974, making them as rare as they are intricate and innovative.
