After starting Uncle Seiko I was inundated with requests to make a bracelet for the 6138 chronograph called “Kakume,” meaning “Square Eyes.” The name comes from the unconventional square sub-dials which stand out among the Seiko chronographs. So, after a long time in the making, here it is. My name on the clasp is an homage to the original without putting the Seiko brand name on it. This has become one of my favorite projects to date and I think you will love it also!
