The Transformation Applicant Wristwatch is a special wristwatch invented by Bulma for Son Gohan.

It's a wristwatch for storing the Great Saiyaman suit which Bulma also made this at Gohan's request. It's normally worn as an ordinary wristwatch, and is used when transforming into the warrior of justice, "Great Saiyaman." The watch itself is like a Hoi Poi Capsule, with the transformation suit being stored inside in particle form. It took Bulma only 2 hours to make this, perhaps because it's simply an application of the same general principle behind capsules. It works on simple function: By pressing the red switch on the right, the transformation suit is instantly equipped; By pressing the left button, the suit is once again stored inside the watch.[1][2]
