What people say

Owners + reviewers, side by side

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

Sartory Billard SB10

The Sartory Billard SB10 features a unique jumping hour and perimeter hour ring design, with functional grater plates that are not practical for actual grating due to a blocked-off side. Owners note the absence of a seconds hand, minute tick marks, and a conventional crystal. On balance, owners appreciate the unique design elements of the Sartory Billard SB10, despite its impractical features.

Yema Superman Titanium Tourbillon CMM.31 Limited Edition

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.
