6138-004x or the Seiko Bullhead is possibly the crown in the line of 6138 models produced by Seiko between 1970 and 1979. Even though this version uses the same movement of the 6138 line, it is somehow special as it uses the “Bullhead” layout of the crown and chrono pushers which can be seen by other vendors in the 70’s such as Omega with its Vintage OMEGA Bullhead Chronograph. Big difference between the Omega and the Seiko – the Japanese bullhead is a very affordable and cool looking chronograph whereas the Omega easily reaches prices beyond $10.000!
The black version with a yellow second hand and blue subdials looks sportier and less retro. On a metal bracelet, it looks almost timeless and is less flashy than the brown version. Both models have reached a cult status among Seiko lovers and the bullhead often makes it to the top rated Seiko watches ever built. Considering the countless models that Seiko has produced, this is quite notable!

The Bullhead is a great watch and almost a must have for every Seiko watch collector. It has the same very robust and reliable 6138 Seiko movement and is probably the coolest looking watch that Seiko has produced in the 70’s. It was produced in a relatively high number and availability of used models is quite good. On the other hand, demand especially for very good and original pieces is very high and prices have increased significantly over the last years.
