1966 Annual Calendar and Equation of Time REF : 49538-52-231-52A

A model following the design spirit of the watches of the 1960s and a tribute to Girard-Perregaux’s technical advances in the field of chronometry, crowned by the Neuchâtel Observatory Centenary Prize.

A timeless design

A classic timepiece with extremely useful complications: annual calendar (date and month indications), equation of time and small second. A thin, entirely polished, round case, softly domed with curved lines (lugs, bezel, sapphire crystal and case-back), strap perfectly integrated to the case for maximum wearing comfort.

The Calibre GP03300-0010

Reliable in-house manufactured movement made of 287 components. The see-through case-back reveals the gold oscillating weight decorated with Côtes de Genève. The Equation of Time indicates the difference between mean and solar time. In reality, the solar day varies in duration from day to day. While the two reference times in question coincide exactly four times per year, the accumulated difference between them can be as much as, for example, 16 minutes in November.
