About this product
Dark grey with diamond markers under a flat diamond-set yellow gold bezel, the sharper of the two settings Rolex offers here — 278343RBR carries the same dial on a domed bezel. Charcoal gives the stones nothing to compete with, in either version. In 31mm Yellow Rolesor on the Oyster bracelet. Calibre 2236 runs at roughly fifty-five hours with Paraflex shock absorbers.
This watch comes with the manufacturer's warranty card, backed up by our own Alan Furman & Co warranty.
