Seiko Prospex SBDC165 (2022)

Seiko Prospex SBDC165 is the Japanese-market code for the blue 1965 Heritage Diver Save the Ocean, also known internationally as SPB297. The 40.5 mm 62MAS-derived case, curved sapphire, black bezel, steel bracelet and 6R35 movement keep the tool-watch package familiar, while the glacier-textured blue dial gives this edition its own atmosphere. A 70-hour reserve makes the modern mechanics useful without changing the basic brief.

When comparing Saudi listings, confirm the SBDC165 and SPB297 pairing rather than treating them as separate watches. Check the dial texture, DiaShield coating, bracelet and full-set documentation, then separate this reference from SPB143 and the other Save the Ocean siblings. The special edition is defined by its surface and exact code, not by a generic 62MAS label.
