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 STGF359

Owners widely praise the Grand Seiko STGF359 for its elegant pairing with an engagement ring. Some owners find the 29mm case size too small for a man's wrist, while others suggest it can be worn by men with smaller wrists, recommending an in-person try-on. One owner notes potential date wheel misalignment requiring servicing. The bracelet has a maximum perimeter of 185mm, with extra links available. On balance, owners value the Grand Seiko STGF359 for its elegant aesthetic, though its small size is a point of consideration.

From video reviewers

The Grand Seiko STGF359 features a 9F quartz movement with exceptional accuracy, deviating by only +/−10 seconds per year. A drawback of the watch is its 40mm case size, which may be a concern for those with smaller wrists. Reviewers disagree on the type of movement, with one praising the 9F quartz and the other highlighting the spring drive movement.

Zelos Spearfish 3

The Zelos Spearfish 3 is widely praised for its exceptional finishing, with razor-sharp polish and flawless brushed transitions that owners feel exceed its price point. The 40mm case is noted for its wearability, and the La Joux-Perret G100 movement offers a 68-hour power reserve, with reported accuracy averaging +2.6 seconds per day. Reviewers highlight the exceptionally smooth bi-directional bezel and a tool-less micro-adjustment clasp described as best-in-class among microbrands. The sapphire sandwich construction and lumed bezel are also cited as desirable features. Overall, owners and reviewers rate the Zelos Spearfish 3 highly for its outstanding finishing and value at its price point.
