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

The Longines Master Collection is widely praised for its excellent value, with owners and reviewers highlighting its attractive finishing and classic, dressy styling. The L893 caliber offers a 72-hour power reserve, and the collection includes models with complications like annual calendars and moon phase chronographs at competitive prices. Some owners note that the bracelet lacks micro-adjustments for a perfect fit, and one reviewer found the case finishing homogenous with pushers that felt cheap. The Master Collection Chronograph is noted for its excellent fit and finish and vintage theme, while the Small Seconds variant's dial features engraved Breguet numerals but the subdial cuts off the "7" asymmetrically, and its case is considered slightly thicker than ideal. One owner reported the moon phase setting mechanism on their chronograph may require service, and the Annual Calendar variant has 30m water resistance.

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.
