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.

Sugess Seestern S434 Pro Diver

Owners widely praise the Sugess Seestern S434 Pro Diver for its impressive finishing and craftsmanship at its price point, highlighting the applied indices that play with light, excellent BGW9 lume, and attractive color options. Specific positive notes include the domed sapphire crystal, short lug-to-lug, and on-the-fly clasp adjustment. However, some owners report quality control issues such as misaligned bezels or indices, while others with V2 models experience no such problems. Caveats include slight bezel back play, light AR coating on the crystal, and a clasp that could be smoother, with one owner desiring a color-matched date wheel. On balance, owners rate the Sugess Seestern S434 Pro Diver highly for its exceptional value and build quality, particularly the dial finishing and lume.
