勞力士，非常精細及非常罕有，18k金自動上弦鏈帶腕錶，配中心秒針、日曆顯示及青金石錶盤，“Submariner”，“Lapis Sub”，型號16618，約1991年製

Reference 16618, the all-gold Submariner, was launched in the mid-1980s, fitted with the calibre 3135 movement and quick-set calendar functions. The model was available with a variety of dial versions, the present lapis lazuli variant being amongst the rarest, due to the challenges in manufacturing stone dials and the short production run with examples only appearing in the E, X and N serial ranges.

The present example is in excellent condition and is one of only a few Submariners with lapis lazuli dials to ever come to market. It can rightly be considered one of the rarest and most beautiful trophies for collectors of Rolex sports watches.
