What people say

Owners + reviewers, side by side

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

AVI-8 Spitfire Smith Automatic

Owners praise the AVI-8 Spitfire Smith Automatic for its dial depth created by elevated numerals, a deeply signed buckle, and detailed case sides. The watch is also noted for being practically mark-free with no dings found, and comes with a barely worn brown leather AVI-8 OEM strap. On balance, owners rate the AVI-8 Spitfire Smith Automatic highly for its detailed finishing and pristine condition.

Sternglas Naos Solar

Owners widely praise the Sternglas Naos Solar for its elegant Bauhaus-inspired minimalist dial, slim profile, and value for money. The scratch-resistant curved sapphire crystal and functional date mechanism are noted as durable features, with one owner reporting good wear over a year. The solar power and accuracy are highlighted as practical advantages over automatic movements, which some find loud. However, opinions are split, with some owners finding the watch underwhelming and cheap-looking, like a toy, while others love its appearance in person and its clean, appealing design as a smartwatch alternative. The stock leather strap is described as decent but basic and potentially short for larger wrists, with one owner advising a third-party replacement for durability. One owner of a different variant noted the date font is too small to be useful.
