Defined by Omega’s modern evolution of its dive watch legacy, the Seamaster Diver 300M stands out through its ceramic construction and precision-driven movement. The blue wave dial variation captures the essence of the ocean through its engraved texture and deep tonal finish, giving collectors a version that feels iconic.

Presents itself in near mint condition with some signs of wear. The blue ceramic dial features Omega’s signature laser-engraved wave pattern, creating depth as light moves across its surface and revealing subtle shifts in tone throughout the day. The blue ceramic bezel frames the dial with a smooth, glossy finish, offering a crisp contrast through its white enamel diving scale. The case and bracelet showcase a refined combination of brushed and polished stainless steel, allowing the watch to reflect light differently at every angle while maintaining its style.

Functions include hours, minutes, seconds, date, unidirectional rotating bezel, and helium escape valve. The screw-down crown on the right side of the case manually winds the movement in its first position when rotated, while pulled to the outermost position it sets the hour, minute, and seconds hands. The date is adjusted by rotating the crown in the intermediate position, allowing for quick and precise setting. The helium escape valve, located at the ten o’clock position, is designed for professional saturation diving where helium can build up inside the watch under extreme pressure. This valve allows that gas to safely release during decompression. The blue ceramic bezel rotates counterclockwise with firm, consistent clicks, enabling accurate tracking of elapsed dive time.

Comes as a complete set, double-boxed, wooden presentation box, watch pillow, international warranty card, Master Chronometer card, pictogram card, instruction manual booklet, and leather wallet holder.

Recognized for its modern ceramic construction and signature wave-pattern dial, this configuration brings together Omega’s dive heritage with a clean blue-on-blue aesthetic that remains one of the most sought-after looks in the Seamaster lineup. A strong fit for someone looking for a versatile daily piece with a sport-forward presence, making it an easy addition to any well-rounded collection.
