Rooted in Omega’s enduring maritime heritage and modern professional dive watch design, the Seamaster Diver 300M stands as one of the most recognizable and technically advanced icons in contemporary horology. Showcasing a laser-engraved blue ceramic wave dial paired with a matching ceramic bezel, it delivers an instantly distinctive presence that balances ocean-inspired character with refined modern execution.

Presents itself in mint condition with little to no signs of wear. Featuring a vivid blue ceramic dial, the laser-engraved wave pattern delivers remarkable depth and fluid motion as light moves across its surface. Showcasing a matching blue ceramic bezel, the glossy finish provides a clean, precise frame that enhances the dial’s ocean-inspired character. Completing the look, the blue rubber strap introduces a refined contrast with subtle red accents, adding visual interest without the use of red stitching.

Functions include hours, minutes, central seconds, date display, unidirectional rotating dive bezel, and an automatic helium escape valve. The screw-down crown on the right side of the case sets the time and quick adjusts the date. The unidirectional bezel tracks elapsed dive time, and the automatic helium escape valve releases internal pressure during saturation diving. Super-LumiNova applied to the hands, indices, and bezel pip ensures clear legibility in low-light conditions while preserving the watch’s refined character.

Comes as a full set, double-boxed with a watch pillow, warranty card, pictogram card, master chronometer card, card wallet, and user manual.

Defined by purposeful beauty and modern maritime character, this Seamaster balances technical confidence with an unmistakably refined presence on the wrist. It delivers quiet assurance and lasting appeal, making it especially compelling for collectors who value depth, authenticity, and enduring design over fleeting trends.
