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.

Borealis Watch Co. Estoril 300 GMT

Owners widely praise the Borealis Watch Co. Estoril 300 GMT for its excellent value, robust build quality, and crisp dial, with reviewers highlighting its exceptionally bright BGW9 lume and dive-ready ceramic bezel. Some owners appreciate the brushed and polished finishes, though one owner noted a desire for a white-painted second hand. The included NATO strap is considered too thick with a loose weave, and the sapphire bezel insert is seen by some as a minor aesthetic departure from its inspirations. Overall, owners rate the Borealis Watch Co. Estoril 300 GMT highly for its impressive build quality and value.
