Reviews

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

RGM Watches Model 455 Classic Chronographs

Owners widely praise RGM watches for their American craftsmanship and special, unusual designs, with one owner finding the tele and tachy scales brilliantly done and perfectly colored. The 38.2mm case size contributes to a diminutive appearance for some, while others find the brand's designs mesmerizing and aspirational. Owners report that RGM watches wear well and garner compliments, with watch experts recognizing the brand's quality. On balance, owners and reviewers rate RGM Watches Model 455 Classic Chronographs highly for its unique American craftsmanship and vintage-inspired dial details.

Longines Avigation Bigeye

Owners and reviewers widely praise the Longines Avigation Bigeye for its vintage military aesthetic, legible dial with a unique "big eye" subdial, and tactile chronograph pusher action. The 41mm steel case wears well, and the boxed sapphire crystal is a notable feature. However, some find the 14.45mm thickness typical for its movement, and the 30-minute sub-dial's three-minute hash marks can compromise reading speed. The stock strap is generally considered unremarkable, and the lack of drilled lugs makes strap changes less convenient. Some owners report minor QC issues with chronograph hand alignment and a loud rotor. Overall, owners rate the Longines Avigation Bigeye highly for its cohesive vintage design and appealing chronograph functionality at its price point.

From video reviewers

The titanium case offers exceptional lightness and balance on the wrist. Reviewers did not reach a consensus on any weaknesses.
