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.

Seiko Prospex LX line

Owners widely report the Seiko Prospex LX line's finishing is a step up from other models, with a case that sits well on the wrist, and some praise the green sunburst dial with blue anti-reflective sapphire crystal as phenomenal. However, owners note the high MSRP limited sales, with some desiring smaller cases and a reduced price, and others experienced quality control issues such as detached second hands and peeling DLC coating, leading to concerns about fragility. On balance, owners feel the Seiko Prospex LX line was discontinued due to pricing that alienated its target market, despite its attractive dial.
