Seiko Chronograph “Baby Jumbo” Petrol 6139-7070 circa 1977 The 1970s was a golden era for automatic chronographs. The “Baby Jumbo” is highly sought after by collectors due to its pioneering movement and striking aesthetic—and a refined variation over some perhaps more funky designs like the Bullhead or UFO. Its petrol blue dial, in particular, adds refinement and depth. While no service history on this one, it is running as well as they come.
