Hand-assembled by Seiko's expert watchmakers, this new Speedtimer is powered by calibre 8R48, which features a column wheel with vertical clutch and a three-pronged hammer that allows instant resetting of all functions. Inspired by the 1972 automatic chronograph model, it has been updated to add a touch of elegance and a sportier look.
