What people say

Owners + reviewers, side by side

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

Astor + Banks Sea Ranger M2

The Astor + Banks Sea Ranger M2 is widely praised for its balanced design, excellent legibility, and strong GADA (go-anywhere, do-anything) capabilities, featuring 300m water resistance and a scratch-resistant coating. Reviewers note its comfortable 40mm case size and good lume, though one source describes it as good but not great. The movement is a Sellita SW200 adjusted by the brand, with accuracy reported around ±8 seconds per day. The pre-order price is $650, with a standard price of $850. On balance, reviewers find the Astor + Banks Sea Ranger M2 to be a compelling option due to its functional design and robust specifications.

Tudor Pelagos Ultra

The Tudor Pelagos Ultra is praised for its 1000 meters of water resistance, METAS-certified Calibre MT5612-U movement, and fully lumed dial and bezel. Reviewers highlight its titanium case and self-adjusting clasp as key features. The Tudor Pelagos Ultra is slightly larger at 43mm than some other models in the line but wears comfortably. Overall, owners and reviewers rate the Tudor Pelagos Ultra highly for its technical specifications and comfortable wearability as a flagship dive watch.

From video reviewers

The Tudor Pelagos Ultra's all-titanium construction provides a lightweight and durable case. One weakness is the lack of lume brightness. Reviewers disagree on whether the helium release valve is a notable feature or a drawback for a more streamlined design.
