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.

Seiko King Seiko KSK

The King Seiko KSK is widely praised for its refined finishing, with owners and reviewers noting its sharp case, faceted lugs, and well-executed dial indices, often comparing its polishing favorably to Grand Seiko. Enthusiasts appreciate its slim, retro design, with some stating it wears smaller than its official size due to the cushion case and close-to-the-wrist feel. The use of the slimline Calibre 6L35 movement is seen as an upgrade, maintaining the watch's slender profile, though some owners express concern over the price point and the perceived value of the movement. Accuracy figures vary, with one owner reporting +5 to +7 seconds per day, while another notes +15/-10 seconds per day. Some owners have noted minor quality control issues such as misaligned screws or a burr on a hand. On balance, owners and reviewers rate the King Seiko KSK highly for its exceptional case and dial finishing at its price point.
