Owners + reviewers, side by side
Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
The Hamilton Jazzmaster Power Reserve Auto is praised by owners and reviewers for its value and history, featuring an 80-hour power reserve caliber H-13 movement. Owners note poor lume, easily scratched polished bezels, and a mineral crystal on the movement display. One owner suggests the 80-hour power reserve is difficult to achieve without manual winding. On balance, owners and reviewers rate the Hamilton Jazzmaster Power Reserve Auto well for its value and history, despite noted drawbacks in finishing and crystal material.
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.
