The 6138 - 3000 chronograph – or “Jumbo” – is a very popular watch made by Seiko in the 70’s and due to its very big size (42mm diameter, 15mm thickness), it can be nicely worn even today.

Even though the Bullhead and Ufo are even bigger in diameter, the Jumbo is the watch that seems to be the biggest of all, explaining the nickname quite well. The reason is the huge dial and a thin outer border which lets watches appear bigger as they actually are.

The most “striking” feature of the 6138 - 3000 is its very timeless and graphical design which still seems modern even after 40 years! It can be worn as a day-to-day watch and probably catches less attention than the Ufo or Bullhead chronographs.

Watch looks sporty to elegant with impressive wrist presence due to its diameter and thickness.
