勞力士，罕有，18k金鑲鑽石自動上弦鏈帶腕錶，配中心秒針、星期、日曆顯示及孔雀石錶盤，“Day-Date”，型號18348，約1990年製

The present reference 18348 is crafted in an 18k gold and diamond-set case and features a highly attractive malachite dial, showing various very fine and subtle shades of green. Most of the hard stone dials, such as the present one, are free from scales or numerals: Rolex probably realized that the material in itself achieves a mesmerizing aesthetic result, and decided to leave the dial without further decorations.
