What people say

Owners + reviewers, side by side

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

Horage Revolution 3 MicroReg

The Horage Revolution 3 MicroReg showcases an innovative external micro-adjustment system for on-the-fly regulation via electromagnetic pulse, a remarkable feat of micro-engineering. This proof-of-concept prototype is still in early development, with a projected launch in late summer 2026 and a founder's price of CHF 3,900. On balance, reviewers highlight the revolutionary regulation technology as the defining characteristic of the Horage Revolution 3 MicroReg.

Seiko King Seiko KSK

The King Seiko KSK is widely praised for its refined finishing, with owners and reviewers noting its sharp case, faceted lugs, and well-executed dial indices, often comparing its polishing favorably to Grand Seiko. Enthusiasts appreciate its slim, retro design, with some stating it wears smaller than its official size due to the cushion case and close-to-the-wrist feel. The use of the slimline Calibre 6L35 movement is seen as an upgrade, maintaining the watch's slender profile, though some owners express concern over the price point and the perceived value of the movement. Accuracy figures vary, with one owner reporting +5 to +7 seconds per day, while another notes +15/-10 seconds per day. Some owners have noted minor quality control issues such as misaligned screws or a burr on a hand. On balance, owners and reviewers rate the King Seiko KSK highly for its exceptional case and dial finishing at its price point.
