OMEGA Releases 8 New ‘Summer Blue’ Watches to Celebrate 75 Years of the Seamaster

This year, OMEGA celebrates an important milestone for an important timepiece. Many watch models have gone by the wayside since 1948, but the iconic Seamaster has endured for those 75 years. One of the most important dive watches in history, the Seamaster rose from the Swiss brand’s military expertise and has since become a standard for both style and underwater performance. It debuted in 1948 to honor the brand’s 100th anniversary, and now, we get to celebrate the collection’s very own 75th anniversary with a series of “Summer Blue” editions that span the breadth of its range.

First up is the Aqua Terra 150M in 38mm stainless steel form, from a series first released in 2002 but inspired by the understated design language of the 1957 Omeag Seamaster 300. It’s powered by the in-house Co-Axial Master Chronometer 8800 automatic movement, which is sealed by the commemorative medallion caseback. Featuring a sunray-brushed blue with a subtle gradient effect, the watch’s dial echoes the calmness of crystal-clear water. Filled with unorthodox light blue Super-LumiNova, the hour markers are even shaped like sailboat hulls.

At 41mm, this Aqua Terra 150M reference is not merely a larger version of the one above. It features a style more true to the line, with a blue teak dial pattern and standard indices — albeit with the same light blue lume as the 38mm watch. Powered by the Omeag Co-Axial Master Chronometer 8900, the timepiece also sports a subtle gradience but comes with two strap options: a stainless steel or an integrated blue rubber strap.

The last of the Omega Aqua Terras for the “Summer Blue” collection is the 150M Worldtimer, which sports a giant map of the Earth at the center of the dial using OMEGA’s laser technology with silver details. Around the map is an hour ring, colored light or dark depending on daytime or nighttime. On the very outside of the dial are 24 city names around the world. Here, the blue dial goes along with both the dive premise as well as the classic GMT style. Also available with stainless steel bracelet or a blue rubber strap, the timepiece is housed in a 43mm case.

Becoming the de facto face of the Seamaster series is the Diver 300M, which was first released in 1993 and has had its own fair share of iterations. This 75th-anniversary version is easily one of the more notable, with a blue laser-engraved wave-patterned dial with light blue lume in the hands and indices. Surrounding the dial is a classic blue ceramic bezel with some light blue enamel on the 60-minute scale. Housed in the 42mm stainless steel case and powered by the caliber 8800, the watch comes with either a steel bracelet or a dark blue rubber strap.

In 1957, the Omeaga Seamaster 300 began the company down a path of innovation unlike anything it had ever done before. The first professional dive watch from OMEGA, the 300 solidified the Seamaster line as the template for all of its divers. In 2021, the brand started modeling these watches after the ‘57 original. This “Summer Blue” edition falls in line with the rest in the 75th-anniversary series with a blue dial, but with a darker gradience compared to the others. Powered by the in-house Co-Axial Master Chronometer 8912, the piece sports a blue ceramic bezel and a 41mm steel case.

Once you get above 300m, the list of dive watches really shrinks down. OMEGA has made some of the most capable divers on the market, and this Omega Planet Ocean 600M is just the tip of the iceberg, with unbelievable capability at just 39.5mm across. Here, the steel case surrounds a blue ceramic dial with a vertical brush pattern. Underneath the commemorative caseback medallion is the Co-Axial Master Chronometer Calibre 8800 automatic.

Aside from the 75th anniversary itself, the big talk of this 8-watch series is the Ploprof 1200M. Launched in the 1970s, the Ploprof (then with a 600m depth rating) has been revived a couple of times over the years (most recently in 2016). However, this “Summer Blue” version is notable for bringing back the case dimensions from the ‘70s: 45mm high and a whopping 55mm across, all within the O-MegaSteel case material. Likewise, the Omega Co-Axial Master Chronometer 8912 movement has to be assembled through the front of the watch due to the return of its monobloc construction. You’ll also notice the giant bezel lock at 2 o’clock and the overt crown cover. Not equipped on the ‘70s versions was the helium escape valve, which is new to the watch. Oh yeah, and the dial and bezel are blue.

Last year, OMEGA released a consumer version of its record-setting dive watches that got sent to the bottom of the Mariana Trench in 2019. Boasting an incredible 6,000m of water resistance, the Planet Ocean 6000M is emblematic of the brand’s commitment to innovation and exploration. It’s only right that the watch be included in the 75th-anniversary festivities. This version sports an incredible deep blue dial whose pattern is made to be an exact representation of the deepest point of the Mariana Trench, with a finish that looks like rippling waters. Shining a UV light on the dial reveals the words, “OMEGA WAS HERE.” It’s housed in a 45.5mm O-MegaSteel case.
