36mm Rolex Day-Date “Tridor” model 18039B in three-colour 18ct gold from approx 1986 on matching white, rose and yellow gold President 8285 bracelet. Comes with brown “luggage” Rolex box, genuine 1986 Day-Date booklet (both being increasingly valuable accessories), our own warranty card and a certificate from the ALR Watch Register confirming that we checked it with them. The silver / diamond dial has been added later – it is a genuine Rolex part, but the yellow coronet betrays the fact that it was intended for an all-yellow gold Day-Date. The white gold winding crown, however, IS correct for the TRIDOR model. We note some signs of wear to the bracelet and that the glass is generic, not from Rolex. All such factors are reflected in the price. There is no current NEW equivalent, but the TRIDOR Day-Date was traditionally more expensive than the plain, white gold version, whose new equivalent today is £31,200.
