Rolex Day-Date 36 Yellow Gold — Bulls Eye Diamond Dial | Ref. 118398

Reference 118398 stands as one of the more extravagant expressions of the Day-Date 36, deploying a bulls-eye dial — concentric rings radiating outward from the centre — rendered in materials that reward close examination. The 36 mm case is fashioned in 18 ct yellow gold, its characteristic warmth amplified by the bracelet's polished surfaces and the bezel set with 60 baguette diamonds whose precise channel-setting creates an unbroken perimeter of faceted stone. The screw-down Twinlock crown seals the case to 100 metres, maintaining the Oyster integrity that has defined Rolex since the 1920s.

The bulls-eye dial pattern — a decorative technique with roots in mid-20th-century Rolex artisanal production — achieves its visual impact through the juxtaposition of concentric enamel or lacquer bands in alternating tonalities. Hour markers here are set with a combination of round and baguette diamonds: 8 round brilliants occupy the primary hour positions, while 2 baguette diamonds punctuate the composition, their elongated rectangular forms contrasting with the round cuts to create rhythmic variety across the chapter ring. Together, dial and bezel present a gemological statement that few contemporary dress watches can rival.

Calibre 3155 — the movement underpinning the 118xxx reference family — is a Rolex manufacture self-winding movement with day and date complications driven by independent rapid-setting mechanisms. Its paramagnetic blue Parachrom hairspring provides stability against magnetic disturbances and temperature variation, while the bidirectional Perpetual rotor maintains continuous mainspring tension during wear. The reference 118398's Oyster bracelet in yellow gold, a departure from the President bracelet more commonly associated with Day-Date references of this era, lends a sportier character to what is otherwise the most jewellery-forward reference in the 36 mm Day-Date range.
