This Omega Seamaster Aqua Terra 150M Worldtimer pairs a 43mm 316L stainless steel case and bracelet with a green ceramic bezel and a laser-ablated titanium dial. The Clone Calibre A8938 delivers the Time Zone function with independent local hour adjustment, plus a rotating 24-hour glass ring and an approximate 36-hour power reserve.
Omega Seamaster Aqua Terra Worldtimer in Green
This 220.30.43.22.10.001 configuration brings the Aqua Terra Worldtimer layout into a 43mm stainless steel case with a matching stainless steel bracelet. The watch is built in 316L steel and paired with a green ceramic bezel that frames the dial with a clean, defined contrast. On the wrist, this is a full-size Worldtimer format with the substantial presence expected from a 43mm case.
The proportions are clearly stated at 43.0mm in diameter, 50.0mm lug-to-lug, and 13.2mm thick, with a listed weight of 168g. That gives this reference a specific physical identity within the Aqua Terra line, and it is part of what sets this model apart from simpler three-hand or standard GMT layouts.
Laser-Ablated Titanium Dial with Worldtimer Display
The dial centers on a laser-ablated titanium map of the Northern Hemisphere in relief, giving this reference its defining visual structure. Around that central map sits a rotating 24-hour glass ring used to track day and night across time zones. The map itself remains static, while the outer 24-hour ring provides the active display element for the worldtime function.
The bezel is specified in green ceramic, and the dial base is presented in the same green family, creating a tightly matched configuration unique to this version. The combination of the relief map, the worldtime ring, and the green ceramic surround gives this reference a more technical dial layout than a standard Aqua Terra while keeping the display organized and legible.
Clone Calibre A8938 and Time Zone Function
Inside is the Clone Calibre A8938, built around the architecture used for this reference rather than a simple base movement conversion. The key functional detail is the Time Zone adjustment: the local hour hand can be moved independently in one-hour increments without stopping the balance wheel. That means the watch can be adjusted for local time changes while the rest of the movement continues running.
This movement also supports the rotating 24-hour ring that works with the worldtime display. Power reserve is listed at approximately 36 hours, giving the watch the mechanical layout expected for this specific complication set. For buyers focused on function rather than appearance alone, the independent hour adjustment is one of the most important details in this build.
Steel Bracelet, Sapphire Crystal, and Case Construction
The bracelet is also produced in 316L stainless steel and fitted with a butterfly clasp. Its alternating finish adds another layer of contrast to the overall build, keeping the bracelet in line with the case and bezel rather than turning it into a separate design element. This keeps the watch visually coherent across the full length of the piece.
Over the dial, the watch uses a sapphire crystal with double-sided anti-reflective coating. That crystal choice suits the layered worldtime display, where maintaining visibility across the map and 24-hour ring matters. Combined with the 316L steel case, green ceramic bezel, and dedicated worldtimer dial layout, this reference is defined by exact technical details rather than generic styling cues.

Buyer Q&A
Questions about this OMEGA watch
Does the world map dial rotate on this watch?
No. The central titanium relief map is static, while the outer 24-hour glass ring rotates to indicate time across different zones.
How does the Time Zone adjustment work on the Clone Calibre A8938?
The movement allows the local hour hand to be adjusted forward or backward in one-hour increments without stopping the seconds hand or disturbing the minute hand.
