What people say

Owners + reviewers, side by side

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

Oak & Oscar The Ashland

Owners widely appreciate Oak & Oscar The Ashland for its handsome design, symmetrical dial layout, and good timekeeping, with one owner reporting -4 seconds per day. Some pre-owned examples show minor marks on the lugs, bezel, and case, along with strap wear, consistent with normal use. On balance, owners value Oak & Oscar The Ashland for its attractive design and reliable performance.

Grand Seiko SLGA001

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.

From video reviewers

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.
