What people say

Owners + reviewers, side by side

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

Hamilton Jazzmaster Skeleton Auto

The Hamilton Jazzmaster Skeleton Auto is praised for its redesigned dial that balances complexity and legibility, forming an "H" logo and highlighting the H-10-S movement. Owners appreciate the 80-hour power reserve and the seamless blend of the bracelet with the lugs. The watch is available in 40mm and 36mm sizes, with prices ranging from A$1,925 to A$2,200, and features 50m water resistance. Overall, owners and reviewers rate the Hamilton Jazzmaster Skeleton Auto highly for its distinctive dial design and impressive power reserve at its price point.

From video reviewers

The 80-hour power reserve from the H-10 automatic movement is a notable strength. Water resistance to 5 ATM is considered on the lower side for the price point.

Halios Seaforth IV

Owners widely praise the Halios Sunburst Blue for its perfect 40mm size, stunning sunburst dial, and excellent lume, with one owner calling it Halios's best effort and a potential "Omega AT killer." The ETA 2824 movement is noted as running smoothly, and the watch is considered a great value with strong resale. Some owners desire larger sizes or different dial colors, and one reviewer found the Sinn 556i more versatile. The sapphire bezel is described as tall and flat, which is a point of contention for some. Overall, owners rate the Halios Sunburst Blue highly for its design, size, and value.

From video reviewers

The sunburst blue dial is a standout feature. Limited water resistance is a shared concern.
