For some years now, serious collectors have looked beyond the headline sports Rolex models, and are snapping up rare precious metal Day-Dates; just look at the world records for vintage "Stella Dials" at the Day-Date 60th Anniversary auction.

Quite remarkably, this solid 18ct white gold Rolex Day-Date ref. 118239 is in 'new old stock condition', retaining its green Rolex hologram sticker. One meticulous owner from new, only worn a handful of times since it was purchased in Edinburgh in July 2006.

The rare diamond-set (with baguette 6 & 9) salmon dial is as aesthetically appealing as it is rare. Note the 'solid' white gold hands, correct for a diamond-dial – plain models have a luminous fill. The Rolex finish to the President bracelet, 36mm body, and sharply-fluted white gold bezel, give this watch importance that cannot be ignored. Despite the discreet colour, white gold has a unique warmth that radiates quite differently from that of stainless steel.

From the era with sequential serial numbering and pre-rehaut engraving, this sapphire glass Day-Date is solidly a classic. President bracelet with concealed coronet clasp; fully waterproof to 100m, and complete with its original lined presentation case, swing tags, and holographic Rolex certificate of authenticity.
