What people say

Owners + reviewers, side by side

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

Longines MASTER COLLECTION CHRONO MOONPHASE

Owners widely praise the Longines MASTER COLLECTION CHRONO MOONPHASE for its beautiful and legible dial, offering significant complications for its value. Accuracy figures vary, with one owner reporting +8 seconds per day and another stating it is their most accurate watch. Some find the chronograph hour hand placement inconvenient, and the date hand can occasionally overlap the hour hand. The watch is noted as being thick, typical of Valjoux-based chronographs, and its 3 bar water resistance limits it to less demanding environments. One owner observed scuffs on the case of their example, and another found the blue on the band and numerals less vibrant than pictured. Overall, owners rate the Longines MASTER COLLECTION CHRONO MOONPHASE highly for its impressive complications and aesthetic appeal at its price point.

Yema Wristmaster Slim Small Seconds CMM.29

Owners widely praise the Yema Wristmaster Slim Small Seconds CMM.29 for its slim 9.5mm case, unique nature-inspired dial, and brushed steel finish. The micro-rotor movement is noted for its 4Hz beat rate and 42-hour power reserve, regulated to -/+ 10 seconds per day. Some owners report concerns regarding the movement and warranty process, while a reviewer questioned the value proposition at its price point and noted minor finishing inconsistencies on a prototype. On balance, the Yema Wristmaster Slim Small Seconds CMM.29 is highly regarded by owners for its distinctive design and comfortable wearability.
