Rare & Important: Officially Certified Chronometer
Citizen Officially Certified Chronometer: Important COSC
CHF 4,800
WHY WE LOVE IT? Well, the Seiko Astronomical Observatory Chronometer (ref4520-8020 or ref4580-8020) is a known icon and has its place in the halls of horology for a very good reason. Citizen to my knowledge never participated in the Astro-Obs competition but obviously wanted to demonstrate it is technically on par with many of the Swiss brands as well by an Official Chronometer-Certification. Et voila, encased in 18K solid gold.
It was serviced and is in technically and optically very good condition. Delivered with a high-quality Ostrich-strap (black), that repeats the color of the hour-indexes & hands.
