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 Monster

On balance, owners and reviewers rate the Seiko Prospex Sea highly for its exceptional value and robust, classic dive watch design.
