Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
Owners widely praise the Corniche Chronograph for its premium look and finishing, often highlighting its elegant and classy appearance and attractive dial depth, especially considering its price point around $400-$455. The 39mm case size is frequently cited as a positive, though some find it too small. The Seiko VK64 meca-quartz movement is noted by some as basic, while others are unbothered by it. One owner flagged a poorly mounted plaque on the case side, and another pointed out a potential misstep with a "mile" marking on the tachymeter scale. Overall, owners rate the Corniche Chronograph highly for its noble and high-quality appearance at the price.
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.

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.
