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.

Seiko 5 Sports SNXS series

Owners widely praise the Seiko 5 Sports SNXS series for its attractive sunburst dials, vintage aesthetic, and excellent value, with many highlighting its comfortable wearability. Reviewers and owners consistently flag the stock bracelet as a significant weakness, often described as jangly, hair-pulling, and difficult to adjust, with a flimsy clasp. The Hardlex crystal is noted as being prone to scratching, and the caseback is described as thick, contributing to a bulky appearance. Accuracy with the movement is reported to be variable, ranging from +/- 1-2 seconds per day to +/- 20 seconds or more, and the movement itself lacks hacking and hand-winding. On balance, owners and reviewers rate the Seiko 5 Sports SNXS series highly for its stunning dials and value, despite significant criticisms of its bracelet and movement limitations.
