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.

Tudor Black Bay One 31 S&G

The Tudor Black Bay One 31 S&G is praised for its quiet luxury, combining brushed steel and warm gold accents for understated charm. Owners appreciate the brushed gold for a casual two-tone look and the champagne dial's surprising legibility. Some find the case sides too thick, and one user expressed a desire for a smaller S&G variant. The watch features the MT5612 movement with a 70-hour power reserve and a date function, within a 200-meter water-resistant case. Overall, owners and reviewers highlight the Tudor Black Bay One 31 S&G's balanced two-tone aesthetic as its primary appeal.
