The numbers, the dial colors, the calibers — laid out so you can stop flipping between tabs.
Owners + reviewers, side by side
Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
The RGM Caliber 20 is lauded for its American-made, vertically integrated horology, featuring a manual-wind movement with a revived motor barrel inspired by classic railroad watches. Reviewers highlight its tonneau-shaped, well-finished 42.5mm x 38.5mm case, a pleasing 9.7mm thickness, and distinctive design elements like the partially skeletonized dial with engine-turned silver sections and blued keystone hands. The watch is water-resistant to 50 meters. On balance, reviewers consider the RGM Caliber 20 a good value for a hand-decorated, US-made mechanical timepiece, with its unique design and build quality being key strengths.
Owners widely praise the Garrick S3 Timepiece for its bespoke experience and spectacular finished product, with one owner finding it beautiful. Reviewers note the hand-frosted brass dial and open-worked dial options, as well as the high level of manual finishing. The manually wound UT-G04 and in-house DB-G07 calibres are regulated to less than 3 seconds per day and offer a 45-hour power reserve. One reviewer flags that the central hands lack sufficient contrast for quick time reading. On balance, owners and reviewers rate the Garrick S3 Timepiece highly for its impressive finishing and bespoke nature.
