What people say

Owners + reviewers, side by side

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

Bremont Supermarine 300M

The Bremont Supermarine 300M is praised for its comfortable 40mm and 42mm case sizes, with owners noting the 42mm wears well on smaller wrists due to its lug design. One owner highlights the 13mm thinness of the 40mm case, considered compact for a 300m diver. The watch is priced at $1375. On balance, owners and reviewers appreciate the Bremont Supermarine 300M for its wearability and compact dimensions, especially for a dive watch.

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.
