Reviews

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

Ontic Utility 40

Owners widely appreciate the Ontic Utility 40's 40mm titanium case, which is hardened for scratch resistance, and its functional dial with ample Super-LumiNova. The solar-powered quartz movement is seen as a practical choice for reliability, though some prefer mechanical movements for tool watches. Some owners find the price high compared to other titanium solar dive watches. On balance, owners and reviewers rate the Ontic Utility 40 highly for its durable titanium construction and practical solar-quartz movement.

Yema Superman Slim CMM.20

Owners and reviewers praise the Yema Superman Slim CMM.20 for its appealing retro design, balanced 39mm case, and in-house CMM.20 micro-rotor movement, with some finding the fish scale bracelet attractive. Concerns exist regarding its $2500/€2,490 MSRP, with some owners questioning its value and noting the potential for QC issues or a "jittery" seconds hand attributed to the new movement. The bracelet's articulation and stamped clasp draw criticism, though some owners report it improves with wear. Overall, owners and reviewers appreciate the Yema Superman Slim CMM.20's vintage styling and unique micro-rotor movement, but its value proposition and some finishing details are points of contention.

From video reviewers

The upgraded CMM.20 micro-rotor movement is a significant enhancement. Reviewers noted the slim profile and redesigned case. One reviewer indicated a significant flaw was discussed, but the nature of this imperfection was not specified.
