RGM Watches Model 455 Classic Chronographs

Owners praise RGM Watches for its American craftsmanship, rarity, and old-school quality, with some finding the designs mesmerizing and aspirational. The tele and tachy scales are noted as brilliantly done with pure vintage coloring, though the smaller time-register contributes to a diminutive appearance. Some owners find RGM watches special and unusual, appreciating direct interaction with the maker, while others find many designs boring. One owner reported a negative experience, finding their RGM diver "horrid," while another "loves" their RGM 801-COE SW. On balance, owners rate RGM Watches highly for its unique American craftsmanship and bespoke potential, despite a high price point.

Grand Seiko SLGW003

The Grand Seiko SLGW003 is praised for its comfortable, lightweight Brilliant Hard Titanium case, meticulous finishing, and a clean, modern dial. Reviewers highlight the new 9SA4 manual-wind movement, noting its attractive finishing, 80-hour power reserve, and accuracy of -3/+5 seconds per day. It is considered a versatile dress watch blending vintage and future Grand Seiko spirit. The €11,700 price is noted as expensive, with some questioning its value. Overall, reviewers rate the Grand Seiko SLGW003 highly for its elegant design and impressive manual-wind movement at its flagship price point.

From video reviewers

The slim profile of the Evolution 9 case is a key strength. Water resistance is a weakness, with figures of 50 meters and 30 meters cited. Reviewers disagree on whether the manual-wind Hi-Beat movement is a rarity or a notable addition.
