What people say

Owners + reviewers, side by side

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

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.

Grand Seiko SBGA427

Grand Seiko SBGA427 owners widely praise its extensive Zaratsu polishing and the "hall of mirrors" effect created by its diamond-cut indexes, complemented by a subtle, reeded dial and a striking green seconds hand. The 39mm case is noted for its comfortable, tapered bracelet, and the 9R65 Spring Drive movement is visible through the caseback. Some owners report the highly polished Zaratsu finish is prone to scuffs and scratches, with one mentioning a scratch near 1 o'clock. The Grand Seiko SBGA427 sold for $3750. Overall, owners rate the Grand Seiko SBGA427 highly for its exceptional finishing and the unique visual appeal of its dial and indexes.
