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.

Yema Navygraf Marine Nationale Quartz

Owners praise the Yema Navygraf Marine Nationale Quartz for its well-made case, clean legible dial, and comfortable 39mm size, with one noting its thin profile for 300m water resistance. Accuracy figures vary, with one owner reporting +6 seconds per day and another seeing it keep within COSC time. Minor criticisms include a steel bracelet with a slight rattle and sharp edges, bent bracelet pins, and in one instance, crooked dial printing. On balance, owners find the Yema Navygraf Marine Nationale Quartz offers good value and wearability, with its French design and thinner case being key highlights.
