What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Seiko Prospex Sea 1965 Heritage Diver's Watch PADI Special Edition

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.

Yema Superman Slim CMM.20

Owners and reviewers praise the Yema Superman Slim CMM.20 for its appealing retro design, balanced 39mm case, and in-house CMM.20 micro-rotor movement, with some finding the fish scale bracelet attractive. Concerns exist regarding its $2500/€2,490 MSRP, with some owners questioning its value and noting the potential for QC issues or a "jittery" seconds hand attributed to the new movement. The bracelet's articulation and stamped clasp draw criticism, though some owners report it improves with wear. Overall, owners and reviewers appreciate the Yema Superman Slim CMM.20's vintage styling and unique micro-rotor movement, but its value proposition and some finishing details are points of contention.
