Longines MASTER COLLECTIONvsYema Superman Titanium Tourbillon CMM.31 Limited Edition

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.

The Yema Superman Titanium Tourbillon CMM.31 Limited Edition is noted for its in-house titanium tourbillon movement offering a 105-hour power reserve and 200m water resistance, alongside a unique asphalt-grained dial. Owners find the 43mm size wearable, with one describing it as a contradictory "toolwatch" with exceptional movement craftsmanship. A reviewer flags the bracelet clasp's extension system as crude. On balance, owners and reviewers highlight the impressive movement and dial as key strengths of the Yema Superman Titanium Tourbillon CMM.31 Limited Edition.
