Undone Basecamp Gmt

Microbrand

The Undone Basecamp Gmt is widely praised for its vintage military aesthetic, comfortable 40mm case, and excellent value under $300, with reviewers noting its smooth, precise bidirectional bezel. Owners and reviewers consistently flag the Lexan polycarbonate crystal as a concern for long-term scratch resistance. The watch uses a Seiko NH34 automatic movement, and while its water resistance is listed as 50 meters, it is reportedly tested to 100 meters. One forum user points out that the orange arrow hand indicates the 12-hour time, not the 24-hour GMT function. Overall, owners and reviewers rate the Undone Basecamp Gmt highly for its versatile vintage design and strong value proposition.
