The community take
Owners talk.
The Seiko Prospex Sea 1965 Heritage Diver's Watch PADI Special Edition is praised for its attractive emerald green sunburst dial with gold accents and its comfortable wearability. Owners note the dial looks gorgeous in the right light, and some find it fits better than other models. The watch features a 40mm steel case, a domed sapphire crystal, and 300m water resistance, powered by the 6R55 movement with a 72-hour power reserve. However, some find the watch wears top-heavy due to its density and case design, and the bracelet clasp is criticized for stamped parts and limited micro-adjustment. The retail price of €1,700 is considered high by some, with sales recommended. Overall, owners and reviewers appreciate the dial's beauty and the watch's comfortable fit, despite some reservations about its weight distribution and bracelet clasp.
