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.

Sternglas Naos Automatik

The Sternglas Naos Automatik is praised for its stylish Bauhaus design and solid build quality for its price, featuring a sapphire crystal and elegant case. However, some dial text is too small and slim for easy readability, and the Milanese strap and clasp are considered lower quality, with the quick-change system also not meeting the brand's advertised standard. One owner found the 38mm model lighter than expected and preferred it over a Seiko SRP703 and an Apple Watch. Overall, owners and reviewers highlight the Sternglas Naos Automatik's attractive Bauhaus design and good value, despite some criticisms of dial legibility and strap quality.
