The Santurce Guaraguao True GMT — Automatic Pilot Watch utilizes the Miyota 9075 automatic true GMT movement. Owners note the Miyota 9075 is an affordable true GMT movement. One owner found the 15mm thickness to be substantial, though the 38mm diameter made it wear well; another user considered the lack of a date window a dealbreaker.
