Reviews

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

Edox CO-1 Carbon Chronograph Automatic

The Edox CO-1 Carbon Chronograph Automatic is a robust 45mm automatic chronograph with a carbon composite case, noted for its lightweight and scratch-resistant properties. Reviewers praise its excellent machining tolerances for the price and the unique, powerboat-inspired design. However, the substantial 45mm size and 16.8mm thickness, along with a heavy clasp, can lead to discomfort on smaller wrists, and some find the dial's shiny elements distracting. It is powered by the Caliber 011 (SW 500) automatic movement with a 48-hour power reserve. On balance, owners and reviewers appreciate the Edox CO-1 Carbon Chronograph Automatic for its unique materials and robust build at an accessible price point, despite some concerns about its size and comfort.

Tissot Seastar 1000

Owners widely praise the Tissot Seastar 1000 for its value, solid build, and 300m water resistance, with reviewers highlighting its comfortable wearability and affordable price point for a sporty diver. Some owners find the bezel difficult to use and note glare from the crystal, while others criticize the lume and bracelet quality, with one owner describing the clasp as flimsy. Accuracy figures for the quartz models are excellent, and the Powermatic 80 movement is considered reliable. Overall, owners and reviewers rate the Tissot Seastar 1000 highly for its strong value proposition as a sporty, affordable everyday watch.

From video reviewers

The 80-hour power reserve from the Powermatic 80 movement is a significant strength. Reviewers did not reach a consensus on any weaknesses.
