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 mesmerizing dial and value, offering numerous complications at its price point. However, its 3 bar water resistance limits wearability, and some find the dial busy with the chronograph hour pointer obscuring the moonphase. One owner noted it is a "thick boi" and the blue is less vibrant than pictured, while another mentioned scuffs on the case and discrepancies with the rotor weight and column wheel compared to the website. The consensus is that the Longines MASTER COLLECTION CHRONO MOONPHASE is a gorgeous, high-horology offering for its price, despite some functional limitations and aesthetic critiques.

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.
