About the 1966 family
The 1966 collection takes its name from the year Girard-Perregaux introduced its first high-frequency automatic movement, the Gyromatic HF. It is the brand's classic round dress line, with slim cases, sober dials and simple lugs, in steel, pink gold and white gold.
The references in this catalog cover time-only models with the automatic GP01800 and GP03300 calibers, as well as calendar and other complicated versions, some with diamond-set bezels. These watches are understated and practical, and buyers mostly look at dial condition, case size and whether the strap and buckle are original.
