Beautiful piece — that’s a classic **Girard-Perregaux manual wind dress watch**, likely from the **1960s to early 1970s**. Here’s what stands out about it:
- **Manual winding movement** (GP Caliber 12 series )
- **Steel case**, elegant slim profile
- **Applied gold baton indices** and **dauphine hands**
- **Minimalist design** with no date complication – a hallmark of pure dress watches
- **Domed acrylic or hesalite crystal**
- Clean, **"GP" logo** at 12 and full "Girard-Perregaux" text — typical of mid-century models
