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

Owners widely report the Tudor Black Bay One 31's polished case and bracelet scratch easily, though its wearability under gloves and robust movement are praised. Some desire more micro-adjustment options on the clasp, and a lack of contrast between the silver dial and hands is noted. The 31mm size may be a consideration for daily wear due to its 50-hour power reserve. On balance, owners and reviewers appreciate the Tudor Black Bay One 31 for its comfortable wearability and robust movement, despite concerns about case scratching and clasp adjustability.
