The Seiko movement in 6139 was known as one of the best chronograph movement Seiko have ever made.
Yes, Zenith El Primero and the Swiss company joint force Caliber 11 are the first to come to watch geek's mind when talked about automatic chronograph, however, it is Seiko that actually launched the first automatic chronograph movement 6139 and made it available in the market in May 1969.
With this 6138 movement, Seiko has taken one step further in the automatic chronograph movement by fitting an hour counter sub-dial in the movement. With this new feature added to the movement, the user of the watch can time accurately beyond 1 hour and for hours within a day.
Seiko movements are known to be durable and tough, so tough that it has been taken into space by astronaut Colonel William Pogue in his 1973 space mission. Pogue took the bigger brother of the 6138 the Seiko 6139 as a personal item during his space mission and the watch survived the mission without a single problem.
There are a number of special 6139 case reference, this particular one 6138 0040 "Bullhead" we are offering was fitted with a black dial with navy blue subdial on top. To give the watch an easy time measure reading, the chronograph was fitted with a contrasting yellow second hand adding the sportiness toward the watch. The Bullhead with its almost 50 years of history has been nicely preserved. The lume of the watch was aged to amazing patina yellow and the tachymeter bezel was aged to an amazing dark grey.
This special reference Bullhead gained its name from the position Seiko place the watch's crown and pushers. The two pump pushers resemble the horn of a raging bull. Seiko placed it in this position to avoid the discomfort the push press against the wrist while wearing and also enable racing drivers trigger the chronograph function of the watch easier. This is truly a unique feature you don't get to see in modern time watches.
The condition of the watch is amazing with its original bracelet and parts. With the hype of panda dial Seiko 6138 keeps rising every day and, it's time for us to find truly unique hidden treasure from the market and looking beyond the hype.
Whether you would like to keep it all original or swapping it with a Nato strap, the Bullhead can certainly help you stand out from all of the usual sports chronographs you see in the market.
