Exceptional example of the famous Seiko 6138-0040, also known as “Bullhead” due to its somewhat aggressive design, the position of the chronograph actuators reminiscent of a bull’s horn and the sub-dials reminiscent of its eyes.

Like the caliber 6139, it was one of the first automatic chronographs launched on the market, featuring the vertical clutch system like its predecessor, but with some subtle changes, such as the addition of the 12-hour accumulator.

It is famous for having been Ayrton Senna's watch, when he was still a kart driver.

This model has appreciated in value very quickly in recent years because it is very difficult to find it completely original, with the dial and case in good condition like this one that we have available in our collection. An unmissable watch for collectors and enthusiasts.

Watch in excellent condition. Dial without damage and with very clear inscriptions, original hands and bracelet. Case with light polishing maintaining the design characteristics. Working perfectly, including chronograph resetting to zero.
