SOLD - Seiko Crown Chronograph Monopusher 45899






Almost ten years before introducing their first automatic chronograph, the 6139, Seiko decided to celebrate the Olympic Games in Tokyo by launching two distinct and specialized watches that would play significant roles in the Seiko legacy.


The first watch was the 6217 World Time, while the second was a monopusher chronograph featuring a 60-second timer, known as the 45899.


Based on the hand-wound Crown movement, the 5719 marked the beginning of a new era for Seiko. The chronograph mechanism incorporated a familiar pillar wheel, but to drive the chronograph wheel, it engaged horizontally with the third wheel through two coupling wheels. The single pusher served the dual purpose of starting and stopping the sweep hand, as well as resetting it.


This particular timepiece is the rare black dial variation and is likely to be the finest example of this model that we will ever have the privilege of offering.

SOLD - Seiko Crown Chronograph Monopusher 45899

  • The monopusher has been well kept in a private collection and it is unused.

    The case is strong with just some barely visible hairline scratches which is expected from a watch of that age. The dial is the main attraction here as it is immaculate and the hands remain intact. The original glass has a bit of haze with few hairline scratches.

    The bracelet is in mint condition and there are no scratches on the clasp.

    The Olympics torch on the case back is firm since it still retains its protective blue film
