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 Lock Chronograph

Owners widely report AVI-8 watches offer a compelling design and are decently well made for the price. The AVI-8 Spitfire Lock Chronograph features a 42mm stainless steel case with curved lugs, a bi-compax meca-quartz movement, and a mineral crystal, with design elements inspired by Supermarine Spitfires. One owner notes that AVI-8 watches are "something different" and "decently well made," though not of "insane quality." On balance, owners and reviewers appreciate the AVI-8 Spitfire Lock Chronograph for its unique design and value proposition.

Longines PrimaLuna Moonphase

The Longines PrimaLuna Moonphase features a fluid case design and a 72-hour power reserve from its automatic movement. Owners note its accuracy averages 1.3 seconds lost per day across six positions, and 3 to 4 seconds on the wrist, performing within COSC standards. Previously, moon phase models utilized quartz movements, a detail that may not appeal to mechanical watch enthusiasts. Overall, owners rate the Longines PrimaLuna Moonphase highly for its updated automatic movement and reliable timekeeping.
