What people say

Owners + reviewers, side by side

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

Citizen Promaster Diver Ecozilla

The Citizen Promaster Diver Ecozilla is widely praised for its reassuringly solid, overbuilt feel and excellent value, especially when on sale. Owners note that the second hand hits its markers well, with one owner reporting all nine of their Citizen watches exhibit proper alignment. The watch features robust 300m water resistance and vibrant lume. However, its substantial 48mm size and 18.6mm thickness create a massive wrist presence, and some owners question its wearability due to its chunky dimensions, with one noting the stainless steel version weighs a ton. On balance, owners and reviewers rate the Citizen Promaster Diver Ecozilla highly for its robust build and excellent value proposition.

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.
