What people say

Owners + reviewers, side by side

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

Citizen Series 8 831

Owners widely praise the Citizen Series 8 831 for its finishing, with one owner noting it exceeded expectations. Reviewers highlight the textured Ice Blue dial and the bracelet's play of light, contributing to a comfortable and luxurious feel on the wrist. The watch features a 40mm ion-plated stainless steel case, a sapphire crystal, and 100 meters of water resistance. It is powered by the in-house Miyota Caliber 9051 automatic movement, which has a 42-hour power reserve and an accuracy range of -10 to +20 seconds per day. On balance, owners and reviewers rate the Citizen Series 8 831 highly for its impressive finishing and dial design at its price point.

From video reviewers

The case finishing, with its contrasting brushed and polished surfaces, is a notable strength. The 40mm case size and comfortable fit are also consistently mentioned. Reviewers did not reach a consensus on any weaknesses.

Eone Relay Bradley

The Eone Relay Bradley is widely praised for its unique, tactile time-telling design and lightweight titanium case. Owners and reviewers highlight its innovative magnetic ball bearing system as a conversation starter and a reliable way to tell time in the dark. However, some users report that the ball bearings can be dislodged or hang after a battery change, and opinions on its value at the $285 price point are mixed. One owner suggests avoiding full retail. More size and color options would be desirable. Overall, owners and reviewers rate the Eone Relay Bradley highly for its ingenious, accessible design and comfortable wearability.
