What people say

Owners + reviewers, side by side

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

Oris Big Crown ProPilot Big Date

Owners and reviewers widely praise the Oris Big Crown ProPilot Big Date for its legible dial and comfortable 41mm size, with many noting its sharp, original design suitable for daily wear. Some reviewers flag the 38-hour power reserve as unimpressive for the price and suggest the movement's decoration could be improved, while others point out the "Big Date" complication is misleading and the bracelet lacks micro-adjustment. The cockpit-style clasp is a noted highlight. Overall, owners and reviewers rate the Oris Big Crown ProPilot Big Date highly for its legibility and comfortable wearability at its price point.

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.
