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.

From video reviewers

The dial's recovered marine plastic construction with textured finish provides distinctive material differentiation at the entry-level dive watch price point, and the sapphire crystal with anti-reflective coating ensures strong on-wrist legibility. The 300m water resistance and automatic movement deliver capable specifications, though bracelet quality and fit remain underspecified across reviews.

Unimatic Modello Quattro UC4 Classic Time Only

The Unimatic Modello Quattro UC4 Classic Time Only features a robust 40mm black DLC case, 13.7mm to 13.9mm thick, with drilled lugs and a fixed steel bezel that balances beefiness with wearability. Reviewers note improved crown action and refinement over earlier models, with a flat sapphire crystal. Its sandwich dial reveals Super-LumiNova BG W9 beneath cut-out indexes, paired with a Seiko NH35A automatic movement. While the movement is considered robust and reliable, one reviewer expressed a preference for a Sellita caliber given the watch's heft. On balance, reviewers find the Unimatic Modello Quattro UC4 Classic Time Only to be a well-refined and wearable tool watch with a distinct military character.
