What people say

Owners + reviewers, side by side

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

Grand Seiko SLGB003

Grand Seiko SLGB003 owners widely praise its lightness and comfort, with a dial that offers a shifting character in different lighting conditions. Reviewers note its compact case size enhances wearability and versatility across wrist sizes. However, one owner found the dial underwhelming, and another reported a date disc issue with lower numbers not changing correctly. Some question the value proposition at around $10,000, citing the bracelet and dial as potential drawbacks, while others highlight the movement and smaller dimensions as significant positives. On balance, owners rate the Grand Seiko SLGB003 highly for its movement and compact dimensions, despite some reservations about the dial and bracelet.

From video reviewers

The watch's exceptional accuracy is a notable strength, with both reviewers highlighting its precise timekeeping. A weakness is the relatively high price point compared to other Grand Seiko models. Reviewers disagree on the ideal case size, with one reviewer noting it's relatively small at 37mm, while the other doesn't mention case size as a concern.

Zelos Spearfish Dual Time

Owners widely praise the Zelos Spearfish Dual Time for its attractive design and the well-executed big date complication. The watch is described as a non-attention-seeking option that looks awesome, with a thickness of 12mm including the crystal and 10mm without. One owner found the $1900 price tag too expensive and uncharacteristic for the brand. On balance, owners rate the Zelos Spearfish Dual Time highly for its attractive design and the well-executed big date complication.
