What people say

Owners + reviewers, side by side

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

Garrick S3 Deadbeat Seconds - Power Reserve

The Garrick S3 Deadbeat Seconds - Power Reserve is praised for its striking design, exceptional finishing, and extensive customization options, featuring a visually arresting open-worked dial and a unique deadbeat seconds complication. Reviewers note its in-house movement is regulated to less than +3 seconds per day, with a 45-hour power reserve. Some find the 42mm size too large and certain movement finishing details lacking relative to its mid-five-figure price. Overall, reviewers highlight the Garrick S3 Deadbeat Seconds - Power Reserve's impressive finishing and customization as key strengths.

Seiko Prospex Sea 1968 Heritage Diver's GMT

The Seiko Prospex Sea 1968 Heritage Diver's GMT is widely praised for its build quality, finishing, and comfortable wearability, offering good value for its price point. Owners and reviewers highlight the attractive silver/white sunray dial, blue ceramic bezel, and the premium feel of the improved bracelet clasp with excellent micro-adjustment. The Caliber 6R54 movement provides a 72-hour power reserve, and real-world accuracy often exceeds its stated range of +25 to -15 seconds per day, with some owners reporting figures around +3 to +5 seconds per day. However, the caller-style GMT functionality is a point of contention for some, who find the GMT scale difficult to read and prefer a flyer GMT at this price. Some also find the crown position at 4 o'clock undesirable, and a few note a lack of dial contrast or illegibility of the inner bezel.
