"197" is an oval shape with a thin metal rim.
Due to the medium-sized lens diameter and plump shape, the sharp atmosphere with reduced vertical width that is imagined when imagining a general oval is softened.

Metal Color: Light gold with vintage finish (The official color name by the brand is VINTAGE SILVER, but the actual impression is not silvery.)

Size:

Front width: 136mm
Front height: 36.5mm
Lens width: 48mm
