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.

Orient 75th Anniversary RA-AC0Q12L30B

The Orient 75th Anniversary RA-AC0Q12L30B is widely praised for its classy, dressy aesthetic, beautiful periwinkle or light blue sunray dial with deep-relief radial grooves, and crisp engraved bezel numerals, all within a compact 39.9mm to 40mm case. Owners consider it a great value, with some noting it looks better in person and is destined to become a classic, punching above its price point. One owner finds the dial color too feminine for a dive watch and considered the dial craftsmanship inferior to the Presage Cocktail series, while another flags the lack of lume as a drawback. The bracelet clasp and end links are consistently considered a weak point, and the steel case is noted as less rounded than other Orient divers. The watch features 200m water resistance and a 46.5mm lug-to-lug measurement. Overall, owners rate the Orient 75th Anniversary RA-AC0Q12L30B highly for its stunning dial and compact size at the price.
