Owners + reviewers, side by side
Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
The Grand Seiko SLGA001 is praised for its impressive technical achievements, including a new, slimmer Spring Drive movement with a five-day power reserve and exceptional accuracy of ±0.5 seconds per day. Reviewers note the 47mm titanium case, despite its substantial dimensions, wears more comfortably due to its titanium construction, short lugs, and virtually scratch-proof finish. The watch features a 600-meter water resistance and is limited to 700 pieces, priced at $11,100. On balance, reviewers consider the Grand Seiko SLGA001 a highly capable dive watch, with its technological advancements in the Spring Drive movement being a key highlight.
The watch's Spring Drive movement, specifically the Cal.9RA5, offers a 120-hour power reserve. A notable trade-off is the watch's relatively large size, with a case diameter of 46.9mm and thickness of 16.0mm, which may not suit those with smaller wrists. The high price point may be a trade-off for some buyers.
Owners widely praise the Spinnaker Fleuss for its retro design, textured dial, and good value, with many noting it looks better in person than in photos. The watch is appreciated for its robust construction and finishing, especially when found at a discount. Some owners report good timekeeping and a decent power reserve. However, the Spinnaker Fleuss GMT is criticized by some for its large case size, which can affect proportions and numeral legibility. One owner experienced a broken crown after a fall, while another noted concerns about the acrylic bezel's durability. The lume is described as adequate but not exceptional. Overall, owners rate the Spinnaker Fleuss highly for its retro aesthetic and value proposition, particularly when purchased on sale.
