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.

Longines SPIRIT ZULU TIME 1925

The Longines SPIRIT ZULU TIME 1925 is widely praised for its handsome, vintage-inspired two-tone aesthetic, featuring a rose-gold capped bezel and dial accents, and is noted for its segment-leading finishing and solid feel. Owners and reviewers highlight the pleasing combination of precious metal with a rugged character. The watch is powered by the ETA-produced L844.4 automatic GMT movement, which is COSC chronometer certified and offers a 72-hour power reserve, visible through a sapphire caseback. Some reviewers flag the 13.5mm thickness as substantial, and the male endlinks may affect wearability on smaller wrists. The Longines SPIRIT ZULU TIME 1925 is priced at approximately $4,350 and includes a bracelet and an additional NATO strap. Overall, owners and reviewers rate the Longines SPIRIT ZULU TIME 1925 highly for its refined vintage-inspired design and excellent finishing at its price point.

From video reviewers

The Spirit Zulu Time 1925 features excellent finishing and a true GMT function. Reviewers questioned the value proposition due to the rose gold being a cap rather than solid.
