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 C1 Moonphase 40

Owners widely praise the Christopher Ward C1 Moonphase 40 for its captivating aventurine dial and photorealistic, luminescent moon, with many receiving compliments and finding it a stylish, lightweight, and comfortable daily wear. The in-house Calibre JJ04 module's 128-year moon tracking is a notable feature. However, multiple owners find the lack of dial indices and bezel markings, along with unlumed hands, makes precise time-telling difficult, with some describing it as more of a jewelry piece than a functional timepiece. One owner experienced a movement issue requiring warranty repair within the first year, and another noted frustration with customer service. The 40.5mm case size is considered sporty by some, and the design is described as "shouty" by a few. On balance, owners highly rate the Christopher Ward C1 Moonphase 40 for its stunning moonphase display and aesthetic appeal at its price point, despite legibility concerns.

From video reviewers

The aventurine dial and Globolight lume are praised for their realistic starry night effect. The 3 ATM water resistance is a significant limitation.

Sternglas Naos XS

Owners widely praise the Sternglas Naos XS for its simple, awesome design, domed sapphire crystal, and clean hands, with one owner highlighting the beautiful blue mother-of-pearl dial and top-notch build quality on a special edition. It is recommended as a durable, refined daily wear watch for around $270, suitable for casual and formal occasions. However, one owner found the Sternglas Naos XS to have a cheap feel and a face resembling a toy, noting it wears smaller than expected, while another described the automatic movement as a bit noisy. On balance, owners rate the Sternglas Naos XS highly for its refined design and value, with specific praise for the mother-of-pearl dial on special editions.
