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 8 870

The Citizen Series 8 870 is praised for its compelling value proposition and modern Japanese design with a sporty edge. Reviewers note its 40mm steel case, glossy dial with applied markers, and the in-house Calibre 0950 automatic movement offering 50 hours of power reserve and enhanced magnetic resistance. The flat sapphire crystal is noted to collect fingerprints, and the solid caseback omits a view of the movement. The limited edition variant features a 40.8mm black DLC-coated case, a carbon fiber dial, and the 0950 movement regulated to -5/+10 seconds per day. Overall, the Citizen Series 8 870 is viewed as a strong offering for its blend of design and features.

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.
