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.

Tissot PRX Titanium

The Tissot PRX Titanium is widely praised for its lightweight titanium construction, impressive machining, and the 38mm size hitting a sweet spot for wearability. Owners and reviewers highlight the Powermatic 80 movement's 80-hour power reserve and anti-magnetic Nivachron balance spring. Some find the colorways and materials less appealing than standard steel options, with legibility noted as a potential issue, and one reviewer expressed a preference for different hand and marker tones against the anthracite dial. Owners discuss the Powermatic 80 movement's use of plastic parts, with some concerned about serviceability while others note Tissot offers movement replacement. On balance, owners and reviewers rate the Tissot PRX Titanium highly for its comfortable wearability and robust movement at its price point.
