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. On balance, owners find the Miyota 9075 movement appealing for its true GMT functionality at an accessible price point.

Owners widely praise the Timefactors Commando PRS-47 for its faithful vintage design, particularly the tropical dial and hi-dome acrylic or sapphire crystal which enhances its visual appeal. The 36mm case size is frequently highlighted as a positive, offering a comfortable and historically accurate fit, complemented by 20mm lug spacing. Some owners note the Miyota 9039 movement's accuracy, with one reporting +1 second per day. Criticisms include the stock bracelet clasp being flimsy or a "solid MEH," and one owner found the 36mm size too small. On balance, owners rate the Timefactors Commando PRS-47 highly for its vintage aesthetic and wearability at the price.
