What people say

Owners + reviewers, side by side

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

Christopher Ward C60 Sapphire Edge

Owners widely praise the Christopher Ward C60 Sapphire Edge for its slim 42mm case and the deep blue, translucent sapphire dial that emulates rippling water, with some finding its execution superior to other brands. The watch is also lauded for its innovative lume, including on the rubber strap, and its significant value. One owner reported their dial cracked internally and the brand denied warranty coverage. Overall, enthusiasts rate the Christopher Ward C60 Sapphire Edge highly for its visually striking sapphire dial and innovative lume at its price point.

From video reviewers

The sapphire dial is a standout feature, offering a unique visual appeal. The bracelet exhibits some rattle. Reviewers disagreed on the dial color, with one noting a deep blue hue and another a striking orange.

Oak & Oscar The Humboldt ExP-02

Oak & Oscar The Humboldt ExP-02 is a 39.5mm stainless steel tool watch featuring a unique, layered aluminum "ghost dial" for legibility and 200m water resistance, powered by a Sellita SW300 movement. Its appeal is limited by a US$2,550 price and an extremely limited production of 20 pieces, with its experimental dial construction done in Chicago. Overall, reviewers highlight the endearing dial and in-house bezel production as key features of the Oak & Oscar Humboldt ExP-02.
