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.

Citizen Series 8 870

The Citizen Series 8 870 is praised for its compelling value proposition and modern Japanese design with a sporty edge. Reviewers note its 40mm steel case, glossy dial with applied markers, and the in-house Calibre 0950 automatic movement offering 50 hours of power reserve and enhanced magnetic resistance. The flat sapphire crystal is noted to collect fingerprints, and the solid caseback omits a view of the movement. The limited edition variant features a 40.8mm black DLC-coated case, a carbon fiber dial, and the 0950 movement regulated to -5/+10 seconds per day. Overall, the Citizen Series 8 870 is viewed as a strong offering for its blend of design and features.
