About the Rolex Day-Date 40 228345RBR
The Rolex Day-Date was introduced in 1956 as the first watch to display the day of the week spelled out in full, cementing its reputation as the ultimate symbol of achievement in fine watchmaking. The modern 40 mm generation, reference 228345, is crafted entirely in Rolex's proprietary 18k Everose gold, an alloy developed in-house for its lasting warm rose hue that resists fading over time. The RBR designation in the reference confirms a factory-set diamond bezel, with baguette-cut and brilliant-cut diamonds carefully selected and set by Rolex craftsmen, elevating an already prestigious timepiece into true haute joaillerie territory. Dial options within this reference span understated elegance to bold luxury, from the earthy warmth of chocolate and olive green to the luminous shimmer of sundust and the classic brilliance of diamond pavé.
What to Look For
When shopping the 228345RBR, pay close attention to the dial suffix, as variations such as RBRP for diamond pavé, RBRC or RBRCDP for chocolate, RBRO for olive green, RBRS and RBR-SUNDDP and RBR-SUNDSMSP for differing sundust configurations, and RBR-WHTRP for white each represent distinct aesthetics and can carry meaningfully different market values. Diamond pavé dials and meteorite or exotic-material dials within the Day-Date 40 family tend to command premiums, while dial condition, box-and-papers status, and proximity to full retail production drive secondary market pricing across all variants.
