Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
The Olech & Wajs Watches NAVICHRON is praised for its comfort and sleekness on a strap, making it sharp for casual wear. One owner notes the ticking is a bit loud. Overall, owners rate the Olech & Wajs Watches NAVICHRON highly for its comfortable wearability on a strap.
Owners widely praise the Yema Rallygraf Meca-Quartz II for its cool retro 70s vibe and car dashboard styling, with its faithful reissue of a small, thin vintage design and tactile pushers noted as strengths, especially considering its price point. The Milanese strap is described as top-notch, and the watch has a substantial, weighty feel that wears smaller than expected, with well-aligned indices and no play in the movement when setting the time. However, some find the meca-quartz ticking not very smooth, the left subdial a "useless" 24h indicator, and the watch overpriced compared to similar models. Owners are split on Yema's quality control, with some reporting no issues and others experiencing or hearing about crooked indices, dial rotation when pushers are depressed or time is set, and a fixed strap loop that limits adjustment. Yema's customer service and communication regarding shipping and strap availability are also criticized by some owners.
The watch's vintage-inspired design and value at its price point are consistently praised. The meca-quartz movement is mentioned as a feature by multiple reviewers.
