Reviews

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Casio MTP-M305L Moon Phase

Owners widely appreciate the Casio MTP-M305L Moon Phase for its surprisingly good moonphase complication at its price point, with one owner calling it the finest watch Casio has ever produced due to its accurate moon almanac function. The indices on the black dial with Roman numerals catch light well, and the brown strap is noted as smooth and not stiff. However, the analog date display is frequently criticized as impractical and difficult to read due to its small size and limited three-day labeling. Overall, owners rate the Casio MTP-M305L Moon Phase highly for its value and unique moon phase complication, despite its legibility issues with the date.

Seiko King Seiko Chronometer

Seiko King Seiko Chronometer 5626-7170 owners praise its rare grey and "Superior Chronometer" dials for their depth and sunburst finishing, which are best appreciated in person. The 36mm case is noted to wear slightly larger due to its lugs. The 5626 movement is recognized as a higher-grade chronometer-adjusted caliber than the 5606, keeping accurate time. A known issue with the 5626 movement is the quick-set date function's susceptibility to failure due to a plastic part, with no replacement part developments reported. On balance, owners value the Seiko King Seiko Chronometer 5626-7170 for its distinctive dial finishing and chronometer-grade movement, despite the potential date function issue.
