Rare & Important: Officially Certified Chronometer

Citizen Officially Certified Chronometer: Chrono Master, Important Japanese


CHF 5,900

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.

This cal920 powered Chronometer was part of the Citizen Chrono Master series -- the finest and most precise movements made by Citizen. The Chrono Master series is comparable to Seikos Grand Seiko grading: placed significantly above the regular Seikos and in finishing, accuracy & adjustment on top of the product-portfolio. This came at a price and this Citizen "Chrono Master" Chronometer Officially Certified was priced more than 4-times the best steel variant: JPY80'000 in 1967.

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.
