The Rolex Datejust 31 (Reference 178274) featuring a pink diamond dial and an 18k white gold fluted bezel is a highly sought-after mid-size luxury timepiece. For a model produced around 2010, it embodies classic Rolesor styling (combining robust 904L stainless steel with precious white gold) and sits perfectly between traditional ladies' sizes and larger unisex models.

• Case Size: 31mm ("Medium" or "Midi" size), offering an elegant, contemporary presence on the wrist.

• Bezel: 18k White Gold Fluted Bezel, which catches the light dynamically and differentiates the 178274 reference from all-steel variants. 

• Dial: Pink Dial adorned with Factory Diamond Hour Markers (10-point diamond setup encased in 18k gold settings). The pink shade ranges from a subtle, soft pastel to a radiant pink sunburst. 

• Material: Rolesor (a signature blend of 18k white gold and premium Oystersteel).

• Movement: Rolex Caliber 2235, a self-winding mechanical movement known for its high precision, reliability, and roughly 48-hour power reserve.

• Crystal: Scratch-resistant Sapphire Crystal with a Cyclops magnifying lens over the date display at 3 o'clock.

• Bracelet Options: Usually paired with either the elegant 5-piece link Jubilee bracelet (often featuring a concealed Crownclasp during this production era) or the sportier 3-piece link Oyster bracelet.
