What people say

Owners + reviewers, side by side

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

Oak & Oscar The Humboldt GMT

Oak & Oscar The Humboldt GMT owners widely praise its exceptional accuracy, often running at or near 0 seconds per day, and its comfortable wearability with subtle design details. The construction quality for the price point, sandwich lume, and anti-magnetic properties are also highlighted.

Overall, owners rate the Oak & Oscar The Humboldt GMT highly for its accuracy and comfortable wearability.

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.
