What people say

Owners + reviewers, side by side

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

Straton Daily Driver MKII

Owners praise the Straton Daily Driver MKII for its AR-coated sapphire crystal and reliable Miyota 6S21 quartz movement at its price, with the comfortable Barton band fitting well for daily wear. The watch features a clean white dial with double panda chronograph subdials, stick indices, and a thin black bezel that owners find visually appealing. One caveat is availability — the watch is difficult to find for sale. Overall, the consensus is that the Straton Daily Driver MKII offers strong value through its sapphire crystal and quartz reliability, marred primarily by scarcity in the market.

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.
