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.

Seestern S456 GMT

Owners widely praise the Seestern S456 GMT for its exceptional value and finishing that exceeds expectations, with one owner noting its accuracy surpasses that of their Seiko 5. The dial displays a pearl-like rainbow effect. Some owners would prefer a bidirectional bezel over the current unidirectional one. The Seestern S456 GMT features an NH34 movement, a 39.5mm case, sapphire crystal, and an adjustable clasp. On balance, owners rate the Seestern S456 GMT highly for its impressive finishing and value proposition at its price point.

From video reviewers

The watch features stunning, detailed finishing that is difficult to top. Reviewers did not reach a consensus on any weaknesses.
