Aqua Terra 150M Worldtimer – Summer Blue 75th Anniversary Edition (43mm)

The Aqua Terra Worldtimer “Summer Blue” is more than a watch; it is a celebration. Released to mark the 75th anniversary of the Seamaster line, this edition wears a unique gradient finish that captures the depth of the ocean. It combines the technical prowess of a worldtimer with an artistic dial that is arguably the finest Omega has ever produced.

Design & Craftsmanship

The Earth in Relief:
The center of the dial is a work of art. Crafted from Grade 5 Titanium, it features a laser-ablated texture showing the Earth viewed from the North Pole. The continents are raised in relief against the blue ocean, creating a 3D effect that is mesmerizing under a loupe.

Summer Blue Gradient:
Omega developed a specific “Summer Blue” tone for this collection. The sun-brushed dial features a gradient finish that darkens towards the edges, symbolizing the transition from shallow to deep water. The hands and hour markers are filled with a unique light-blue Super-LumiNova to match.

Global Connectivity:
Surrounding the map is a 24-hour indication ring split into light and dark blue sections for day and night. The outer circle lists global destinations, allowing you to track time across every time zone simultaneously with a single glance.

Technical Specifications

On The Wrist

The 43mm case has presence but sits surprisingly well thanks to the integrated-style bracelet links. The “Summer Blue” colorway is refreshing—it feels lighter and more casual than the standard blue model. It’s a sophisticated travel companion that doubles as a piece of commemorative art.
