While the Diver 300M is built for wetsuits, the Omega Seamaster Aqua Terra 150M (41mm) and the breathtaking Aqua Terra GMT Worldtimer (43mm) represent the pinnacle of versatile “GADA” (Go Anywhere, Do Anything) horology. What makes the VS Factory (VSF) Aqua Terra one of the most celebrated accomplishments in replica watchmaking history is not its dial—it is the true-clone Calibre 8900 and 8938 visible through the sapphire caseback.
- Not a Decorated Plate—A Purpose-Built Twin-Barrel Clone: Unlike competitors that glue a decorative Omega bridge over a noisy Miyota 8215, VSF built the Calibre 8900 from the ground up with dual series-coupled mainspring barrels delivering a 60+ hour power reserve.
- True Independent Jumping Local Hour Hand: Just like the genuine Omega Master Chronometer 8900 (and the Rolex GMT-Master II), Position 1 of the crown jumps the hour hand in 1-hour steps forward or backward to change time zones or advance the date.
- Grade 5 Titanium Laser-Ablated Worldtimer Map: On the 43mm Worldtimer, the central 24-hour northern hemisphere relief map is laser-carved onto a genuine titanium plate—not printed or stamped.
- 25,200 vph Co-Axial Beat Rate: VSF tuned the escapement to oscillate at the exact genuine Omega Co-Axial frequency of 25,200 vph (3.5 Hz).
1. The 43mm Aqua Terra GMT Worldtimer: A Miniature Planet on the Wrist
Examine our Omega Seamaster Aqua Terra 150M GMT Worldtimer VSF Edition closely. Surrounding the central titanium topographical map of Earth—where deep blue oceans meet raised, warm-toned continents—rotates a 24-hour hesalite crystal ring divided into light blue (daytime) and dark blue (nighttime) halves. Around the outer perimeter sit 24 global destinations printed on two levels: London (UTC) in red, cities observing daylight saving time in silver, and non-DST locations in blue.

2. Aqua Terra 150M 41mm & 43mm GMT: Yacht-Deck Elegance
For collectors who prefer a cleaner 41mm dress-sport silhouette, the horizontal “teak concept” dial—inspired by the wooden decks of luxury motor yachts—comes alive in deep ocean blue, emerald green, silver opaline, or jet black, such as our Omega Aqua Terra 150M 41mm Black Teak Dial, Omega Aqua Terra 150M 43mm GMT Black Textured Dial VSF, and the classic Omega Seamaster Aqua Terra Co-Axial Stainless Steel.

Collector FAQ & Pre-Shipment QC Answers
How do you change the date on the VSF Aqua Terra 8900?
Just like a genuine Omega Calibre 8900, there is no traditional quickset date position. Pull the crown to Position 1 and rotate it to jump the local hour hand in 1-hour increments—passing midnight twice advances (or reverses!) the date cleanly.
Does the 24-hour ring on the VSF Worldtimer actually work?
Yes, the inner 24-hour day/night crystal ring rotates continuously once every 24 hours, allowing you to read the exact hour in all 24 world cities simultaneously.
