What people say

Owners + reviewers, side by side

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

Ferro Time Master 70

The Ferro Time Master 70 is praised for its distinctive 1970s-inspired polygon case and visually striking silver dial with orange accents and unique lume colors. Owners appreciate the retro design with unique touches, clean dial, and lumed markers, along with the smooth winding of the Miyota 9039 movement. Its 39mm diameter, 10.4mm thickness, and 47mm lug-to-lug dimensions contribute to comfortable wearability, further enhanced by a well-executed faux-single link bracelet featuring a practical on-the-fly micro-adjustment clasp. On balance, owners and reviewers rate the Ferro Time Master 70 highly for its retro design and comfortable wearability.

Yema Navygraf Marine Nationale Quartz

Owners praise the Yema Navygraf Marine Nationale Quartz for its well-made case, clean legible dial, and comfortable 39mm size, with one noting its thin profile for 300m water resistance. Accuracy figures vary, with one owner reporting +6 seconds per day and another seeing it keep within COSC time. Minor criticisms include a steel bracelet with a slight rattle and sharp edges, bent bracelet pins, and in one instance, crooked dial printing. On balance, owners find the Yema Navygraf Marine Nationale Quartz offers good value and wearability, with its French design and thinner case being key highlights.
