In 1932, Omega launched its Marine watch—the first timepiece of use to civilian divers, tested 73 meters under Lake Geneva’s surface. Thus began the brand’s legacy of underwater design, pushing the limits of what functional, luxury accessories could withstand and conquer.

That history culminates in the Seamaster, Omega’s ultimate marriage of elegance and cutting-edge water-resistant technology. First released in 1948, the watch is marked by its own evolution—with each model introduced over the years, it plunges further, set apart by its distinctive seahorse logo and a mission centered on ocean exploration and conservation.

Now, the Seamaster celebrates its 75th anniversary with a seven-model, 11-watch collection. Varnished in deep Summer Blue, and decorated with a commemorative Poseidon caseback, these new additions span any mariner’s needs, encompassing both style and utility: the Aqua Terra, the Worldtimer, the Seamaster 300, the Diver 300M, the Planet Ocean, the Ploprof, and finally, the Ultradeep.

Here, Document provides a closer look at the latest iterations of the Seamaster, against a suitable backdrop—the Mediterranean coast. It’s an easy choice for the launch of Omega’s latest venture, diving down into the boundless unknown.
