What people say

Owners + reviewers, side by side

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

Spinnaker Hass Automatic

The Spinnaker Hass Automatic is a 43mm watch featuring an NH35 movement and sapphire crystal, with owners highlighting its beautiful dial. Some find Spinnaker watches, including this model, to be on the thicker side, with one owner describing the Hass X MCS Blue Fade variant as comically large and chunky. The Spinnaker Hass Automatic was offered at $445 USD as part of a special collection with customized elements, and a limited edition of 200 pieces was also available for $195 shipped. On balance, owners and reviewers note the attractive dial as a key positive, though some express reservations about the watch's thickness.

Longines HYDROCONQUEST GMT

The Longines HYDROCONQUEST GMT is widely praised for its excellent finishing, with some comparing it favorably to higher-end dive watches, and its attractive blue sunburst dial. Owners note its practical true GMT complication and robust 41mm brushed case with ceramic bezel, powered by a movement offering a 72-hour power reserve. Some in the community find the round markers at 6 and 9 disrupt dial symmetry, though others appreciate this design element. A common criticism is the difficulty in reading the tiny GMT text beneath the hour markers, and the absence of a quick date adjust feature. One owner reported a sharp feeling on the bracelet's clasp, and another flagged mismatched date wheel colors on certain dial variants. Overall, owners and reviewers consider the Longines HYDROCONQUEST GMT a strong value proposition for a traveler's dive watch, citing its build quality and GMT functionality as key strengths.
