Certina DS Action ChronovsEdox CO-1 Chronograph

Owners widely praise the Certina DS Action Chrono for its immaculate finishing, build quality superior to similarly priced competitors, and impressive accuracy, with one owner noting it did not lose a second in a week. The 1/100th second capability of the Precidrive quartz movement is highlighted as a standout feature, and its overall look and comfortable rubber strap are also appreciated. Some reviewers and owners desire polished chamfers on the brushed steel case and find the "action" text on the dial unnecessary. A few owners note that the similarity between the hour and minute hands can hinder quick time reading, and one owner mentions free play in the quartz movement can require a few attempts to align the second hand. Overall, owners and reviewers rate the Certina DS Action Chrono highly for its exceptional finishing and accuracy at its price point.

Owners widely praise the Edox CO-1 Chronograph's unique carbon-ceramic-resin case for its distinctive striped look and lightweight feel, even with its 45mm diameter. However, wearability is a point of contention; reviewers and owners note the 45mm case size and bulky clasp can be uncomfortable, particularly for smaller wrists. Some find the dial's shiny elements and the single Arabic numeral distracting, while one owner reports trouble-free ownership for six years with good accuracy and a durable build. Overall, owners and reviewers find the Edox CO-1 Chronograph to be a robustly built watch with a distinctive aesthetic, though its substantial size and clasp design present wearability challenges for some.
