Serviced in December of 2025 by a professional watchmaker. Runs and keeps time. Will include service receipt upon purchase. The caliber 666 is a very slight (if any) variation on the caliber 663, the world’s very first microrotor movement alongside the Buren 1000. This movement is the reason that Universal Geneve had to put “patent pending” on their own microrotor for a while.
Overall good condition. Some loss to the chapter ring printing along the outer edge of the dial. Darkened, original lume. Hands are likely relumed at some point as they look a bit lighter. Otherwise original. Original Hamilton and Automatic dial text well intact. Replacement crystal. Original crown.
A chance to own a very horologically important timepiece, when Hamilton was at their peak. Polerouter looks and movement tech for a fraction of the cost :)
