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.

Praesidus Service Watch

Owners widely praise the Praesidus Service Watch for its 38mm size and solid build quality, with the domed crystal providing vintage distortion and the unbranded dial appealing to history enthusiasts. However, owners report jumpy hand sensitivity when setting the time. One owner experienced a scratchy crown and a noisy rotor on their DD-45, which persisted after warranty service and eventually led to the crown locking mid-way. Concerns about slow customer service and a negative reputation for Praesidus's support are also noted by owners. On balance, owners appreciate the vintage aesthetic and wearability of the Praesidus Service Watch, though persistent customer service issues temper enthusiasm.

From video reviewers

The 38mm case size is a strength for those preferring smaller watches. The dial may show slight discoloration or unevenness in finish.
