What people say

Owners + reviewers, side by side

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

Lorier Olympia SII

Owners widely praise the Lorier Olympia SII for its excellent value and vintage aesthetic, highlighting the robust Seiko NE88 movement and crisp chronograph pushers. The 39mm case is noted for wearing well, with its layered design effectively managing the 13.8mm thickness. Some owners prefer the hesalite crystal for its aesthetic, while others would like a sapphire option. The bracelet is described as functional but can be a hair nipper. Overall, owners rate the Lorier Olympia SII highly for its execution of a vintage chronograph at an accessible price point.

Yema Wristmaster Slim CMM.20

The Yema Wristmaster Slim CMM.20 is widely praised for its compelling integrated bracelet design and comfortable 39mm wearability. Reviewers highlight its impressive value, featuring an in-house CMM.20 micro-rotor movement with a 70-hour power reserve, adjusted to -3/+7 seconds per day, all within a slim 9mm case. Some note the domed sapphire crystal can produce glare and the dial text is quite small. On balance, reviewers rate the Yema Wristmaster Slim CMM.20 highly for its integrated design and value proposition with a micro-rotor movement.
