Omega Seamaster Diver 300M Summer Blue

In 2023, Omega introduced the “Summer Blue” collection to mark 75 years of the Seamaster, an anniversary that celebrates the brand’s long-standing relationship with the sea. Rather than a simple colour update, the collection explores depth through design, with each model reflecting its water resistance through a carefully graduated dial.
 
This Seamaster Diver 300M is perhaps the most recognisable expression of that idea. Its 42mm stainless steel case retains the familiar design that has defined the modern Diver 300M, complete with twisted lyre lugs, a helium escape valve, and a unidirectional bezel with a blue ceramic insert. Built for genuine use, it offers 300 metres of water resistance, combining professional capability with everyday wearability.
 
The dial is where this reference truly distinguishes itself. Crafted from ceramic and finished in Omega’s “Summer Blue,” it features a subtle gradient that darkens toward the edges, reflecting the watch’s depth rating. The signature wave pattern remains, adding texture and identity, while the use of a unique light blue Super-LumiNova® ensures excellent legibility in low light, giving the watch a distinct character both day and night.
 
Turning the watch over reveals a commemorative case back, decorated with a Seahorse medallion set against an ocean backdrop, an elegant nod to the Seamaster’s heritage.
 
Powering the watch is the Omega Co-Axial Master Chronometer calibre 8800. Certified by METAS, it offers a 55-hour power reserve and is resistant to magnetic fields of up to 15,000 gauss. Featuring a free-sprung balance and silicon balance spring, it represents Omega’s continued focus on precision, durability, and technical innovation.
 
This example is fitted to a blue rubber strap with a steel pin buckle, reinforcing its sporty, summer-ready aesthetic while ensuring comfort on the wrist.
 
Originally purchased in July 2024, the watch is offered as a full set, including its presentation box with travel case, instructions and warranty card covering the watch to July 2029.
 
Combining a fresh, contemporary design with the proven capability of the Diver 300M, the “Summer Blue” edition is perfect for sunny days home or abroad.
