What people say

Owners + reviewers, side by side

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

Citizen Promaster Skyhawk U830

The Citizen Promaster Skyhawk U830 is praised for its updated 43mm titanium case, legible memory-in-pixel display, and cleaner, less cluttered design compared to previous versions. Reviewers highlight its versatile contemporary look and enhanced functionality from the caliber U830, while owners appreciate the MIP display and screw-down caseback. Some users find the interface clunky and the face busy, particularly noting the "calendar" label and the lack of radio or GPS time synchronization, with one owner finding the 45mm size and busy subdials less useful for non-pilots. On balance, owners and reviewers rate the Citizen Promaster Skyhawk U830 highly for its impressive technology and improved legibility in a contemporary package.

Oak & Oscar The Humboldt GMT SAR Edition

Oak & Oscar The Humboldt GMT SAR Edition is praised for its anti-magnetic properties, sandwich lume dial, and overall construction quality for its price point. It features a brushed Grade 5 titanium case, a navy blue sandwich dial with an orange minute track and seconds hand, and a Sellita SW330 movement with a 56-hour power reserve. Minor drawbacks noted include bracelet sizing adjustment and lume brightness. On balance, owners and reviewers rate Oak & Oscar The Humboldt GMT SAR Edition highly for its robust construction and unique dial design at its price point.
