This 31mm mid-size Datejust with blue diamond dial is a beauty, and currently retails at Rolex for £7,300. The 18ct white gold fluted bezel and 10 scintillating Rolex-set diamonds really pop against the deep blue sunburst dial and complement the elegant (and supremely comfortable) Jubilee bracelet. Presented in fantastic condition with its original Rolex box and UK stamped certificate, this 178274 is waterproof to 100m and powered by the ultra reliable 2235 automatic calibre movement with date.
