OMEGA Seamaster Ploprof 1200M Summer Blue Watch marks a significant milestone for the brand, created to celebrate the 75th anniversary of the Seamaster collection. As one of the most extreme professional dive watches ever produced by OMEGA, this modern Ploprof combines historical design DNA with contemporary materials, advanced engineering, and a distinctive Summer Blue aesthetic that enhances both functionality and collectability.
The case of the OMEGA Seamaster Ploprof 1200M Summer Blue Watch is crafted from OMEGA’s proprietary O-MEGASTEEL alloy, a material known for its exceptional hardness, corrosion resistance, and long-term durability in extreme marine environments. Compared with traditional stainless steel, O-MEGASTEEL offers superior resistance to saltwater exposure and mechanical wear, making it ideal for a professional-grade saturation diving instrument.
The case dimensions have been refined to 55mm by 45mm, offering improved ergonomics while preserving the unmistakable Ploprof silhouette. The watch returns to a monobloc case construction, a hallmark of the original 1970s Ploprof models, enhancing structural integrity under extreme pressure. A large screw-down crown and the iconic bezel locking mechanism at 2 o’clock reinforce its purpose-built tool watch character. The safety pusher is accented with a blue ceramic ring, visually linking it to the dial color scheme.
Numerous refinements improve legibility and usability. The bezel teeth are smaller and more closely spaced, allowing for precise operation even with diving gloves. The enlarged minute scale on the ceramic bezel enhances elapsed-time readability, while the dial features slimmer hour markers to create a cleaner visual balance. The absence of a date window reflects feedback from professional divers and tool watch purists who prioritize clarity and symmetry.
The dial of the OMEGA Seamaster Ploprof 1200M Summer Blue Watch showcases a brushed and frosted surface with a gradient Summer Blue finish. This color transitions from lighter tones at the center to deeper blue hues toward the edges, symbolizing increasing water depth. Lacquered hands and applied markers are filled with light-blue luminescent material, ensuring high contrast and excellent visibility in low-light underwater conditions.
Powering the watch is the in-house OMEGA Caliber 8912 automatic movement. This Master Chronometer-certified caliber operates at 25,200 vibrations per hour and provides a 60-hour power reserve. It offers exceptional resistance to magnetic fields and meets the highest standards of precision and reliability required for professional diving applications.
The caseback features a laser-engraved commemorative Seamaster hippocampus emblem, surrounded by a wave-patterned border exclusive to the 75th anniversary collection. Water resistance is rated to an impressive 1200 meters, confirming the watch’s status as a true professional dive instrument.
The OMEGA Seamaster Ploprof 1200M Summer Blue Watch is paired with a blue rubber strap designed for comfort, flexibility, and durability in demanding underwater conditions. This model stands as one of the most technically advanced and visually distinctive Ploprof references ever released.
