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.

Baltic Hermétique Summer

Reviewers highlight the Baltic Hermétique Summer's compact 37mm brushed case with a polished bezel and 150 meters of water resistance. The watch features glossy dials in bright colors with raised BGW9 Super-LumiNova indices that emit a strong blue glow, and it comes with color-matched FKM rubber straps or Baltic bracelets. The Miyota 9039 movement supports hacking and hand-winding. However, the recessed crown can be difficult to manipulate if fingernails are not long enough, and the movement has a stated accuracy of -10/+30 seconds per day. Overall, reviewers praise the Baltic Hermétique Summer for its well-balanced, colorful dials and strong lume at an affordable price point.
