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.

Hamilton Khaki Navy Scuba Auto

Owners and reviewers widely praise the Hamilton Khaki Navy Scuba Auto for its exceptional value, robust construction, and distinctive dial designs, with many highlighting the 80-hour power reserve provided by the H-10 movement. The watch is frequently noted for its utilitarian dial, legible lume, and tactile bezel action. However, the 43mm case size is a recurring point of contention, with several sources deeming it large for everyday wear, though some owners find it comfortable and appreciate its substantial feel. One reviewer points out that the steel bracelet could benefit from a taper and a quick-adjust clasp, and another notes the unlumed bezel pip as a minor area for improvement. Overall, the Hamilton Khaki Navy Scuba Auto is highly regarded by owners and reviewers for its strong value and appealing tool-watch aesthetic, with the 43mm case size being the most significant consideration for potential buyers.
