Reviews

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

Citizen Promaster Diver Automatic

Owners widely praise the Citizen Promaster Diver Automatic for its lightweight titanium construction, comfortable wear, and good specifications for the price. One owner highlights its accuracy and dynamic dial made from recycled materials. Some find the bezel action spongy and the bracelet subpar, with the overall finish described as basic due to the brushed titanium. A reviewer notes a slightly misaligned bezel and chapter ring, expressing a preference for sapphire crystal and ceramic bezel. Overall, owners rate the Citizen Promaster Diver Automatic highly for its lightweight titanium build and value, despite minor criticisms regarding finishing and bezel action.

Edox CO-1 Chronograph Automatic

Owners widely praise the Edox CO-1 Chronograph Automatic for its robust build, scratch-resistant case and sapphire crystal, and well-assembled Swiss automatic chronograph movement. Reviewers and owners alike note the 45mm case's substantial presence, with some appreciating its modern materials like carbon composite and ceramic bezel, while others find the blue carbon fiber dial and shiny elements distracting. A common point of contention is the clasp, described by some as uncomfortable and by others as a source of wrist discomfort, though the vanilla-scented rubber strap receives positive mentions. One owner reports a minute hand issue that was a simple fix, while another notes six years of ownership with consistent accuracy and durability. Overall, owners and reviewers find the Edox CO-1 Chronograph Automatic to be a well-specified and durably built tool watch, with the primary trade-offs being its large size and divisive clasp design.
