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.

Zelos Helica Moonphase

Owners widely praise the Zelos Helica Moonphase for its gorgeous aventurine dial, unique industrial-dress aesthetic, and comfortable wearability, with one owner calling it spectacular and another their favorite Zelos. The moonphase complication is frequently highlighted as beautiful, though some find the double moon distracting or the dial cluttered. A manual-wind movement combined with a screw-down crown is noted as a drawback by some, requiring adjustment and potentially feeling fragile when fully wound, while one owner reports a 43-hour power reserve. On balance, owners rate the Zelos Helica Moonphase highly for its stunning aventurine dial and unique design at its price point.
