🔎 Case Notes

The grey-dial Seamaster Diver 300M is one of the more distinctive modern configurations in Omega’s lineup.

The 42 mm stainless-steel case is paired with a polished grey ceramic dial, laser-engraved with the familiar Seamaster wave pattern, and a blue ceramic unidirectional bezel. On the matching blue rubber strap, the watch feels sportier and lighter than its bracelet-equipped siblings while retaining the same technical capability.

The grey and blue combination gives the watch a noticeably different personality from the more common black, blue, or white versions. Depending on the light, the ceramic dial can shift from cool silver-grey to a deeper metallic tone, while the blue bezel and strap keep the overall presentation unmistakably maritime.

This example dates from 2022 and presents in excellent pre-owned condition. It includes its box, papers, and cards and is fitted to accommodate approximately an 8-inch wrist.

A 2022 warranty card should also leave some portion of Omega’s five-year international warranty remaining, subject to the exact activation date and Omega warranty terms.

🌟 Collector Provenance

The fourth-generation Seamaster Diver 300M brought the model fully into Omega’s modern technical era while preserving the visual language that made the line famous.

The wave dial returned, but now laser engraved into ceramic. The bezel became ceramic as well, and the movement moved to Omega’s Master Chronometer Calibre 8800, visible through the sapphire caseback.

Within that generation, the grey-dial version stands apart from the more familiar black and blue models. It keeps the same core architecture but feels more contemporary and less traditional, especially on the blue rubber strap.

🌟 Technical Provenance

The Calibre 8800 is one of the strongest reasons to own this generation of Seamaster.

It provides approximately 55 hours of power reserve, Co-Axial escapement, and METAS Master Chronometer certification, including resistance to magnetic fields up to 15,000 gauss.

That technology sits inside a genuine 300-meter dive-watch case with screw-down crown, helium escape valve, ceramic bezel, and sapphire display back.

🧾 From the Case File

This configuration is especially easy to wear.

The 42 mm case still has the presence expected from a modern Seamaster, but the rubber strap removes a meaningful amount of weight compared with the steel bracelet and gives the watch a more relaxed, athletic feel.

The grey ceramic dial is the visual highlight. It reflects light in a way that darker Seamaster dials do not, while the blue bezel and strap keep the color palette cohesive.

This 2022 example adds excellent condition, BPC, generous 8-inch fit, and likely remaining factory warranty, making it a strong alternative to buying new.

🗝️ BST Verdict

A modern Seamaster with one of the most interesting color combinations in the range.

The grey ceramic wave dial and blue rubber give the watch real personality, while the Calibre 8800, Master Chronometer certification, and 300-meter capability provide the substance underneath.

👉 Every case deserves a closer look.
