What people say

Owners + reviewers, side by side

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

Phoibos Eagle Ray No Date

Owners widely praise the Phoibos Eagle Ray No Date for its value at the price point. One owner notes the watch is a great purchase with no regrets, and is unbothered by its lume. The Phoibos Eagle Ray No Date features a 41mm steel case and a Miyota 9015 automatic movement with a 42-hour power reserve. However, one owner received a non-working watch and reported difficulty obtaining a refund, citing horrible customer service. On balance, owners rate the Phoibos Eagle Ray No Date well for its value, though customer service experiences can vary.

From video reviewers

The Phoibos Eagle Ray No Date features a high-beat Miyota 9015 movement, which is a notable strength. A weakness of the watch is its relatively weak lume brightness. Reviewers disagree on whether the added features of the Ceramic model justify the extra cost, with one reviewer finding it worth the extra cost and another noting it's a trade-off for the No Date model.

Seiko King Seiko KSK

Owners and reviewers widely praise the King Seiko KSK's sharp, faceted case design and harmonious mid-century aesthetic. Its compact 38.1mm or 37mm size and slim 10.7mm thickness are noted as highly wearable. However, accuracy is a point of contention, with one reviewer reporting a wide range of +25 to -15 seconds per day for the 6R31 movement, while others criticize the standard 6R movement as too thick and a departure from the brand's history. Water resistance is consistently cited as limited to 50 meters, and one owner reported misaligned screws on the caseback and clasp. On balance, owners and reviewers find the King Seiko KSK appealing for its design and wearability, though the movement choice and accuracy are significant drawbacks for some.
