劳力士，极罕有，18K金镶钻石及红宝石自动上弦链带腕表，配中心秒针、星期及日历显示，DAY-DATE，型号18068，约1984年制

The present reference 18068 is part of a very limited number of such jewelled "Day-Date" models, furthermore distinguished by its unusual day and date windows. The date is red burgundy coloured with the calendar indications gilt printed to match the ruby-set numerals and bezel. Highly attractive, it is one of Rolex's most famous models but with an added flare.
