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.

Boldr Expedition Enigmath

The watch's slide rule function is a convenient feature, allowing for calculations on the go. One potential drawback is the use of the Japanese Miyota 9039 movement, which may be a trade-off for some buyers. Reviewers disagree on whether the quick 'on the fly' adjust bracelet is a more significant advantage than the watch's sapphire crystal for durability and scratch resistance.
