These are authentic Rolex Datejust models featuring iconic two-tone construction with stainless steel and 18k yellow gold. Each watch showcases a sleek black dial adorned with diamond hour markers (including Roman numerals at 6, 9, and 12 o’clock), a date window at 3 o’clock with Cyclops magnifier, and the signature Rolex crown logo. The fluted bezel is crafted in polished gold, complementing the Jubilee bracelet—a five-piece link design combining brushed steel and gold links for refined comfort and durability. Both timepieces are self-winding mechanical chronometers, certified by COSC, with Oyster Perpetual movement ensuring precision and water resistance up to 100 meters. The larger model appears to be the classic 36mm Datejust, while the smaller is likely the 26mm or 31mm Lady-Datejust—ideal for elegant daily wear, business settings, or formal occasions. Their timeless design blends luxury, heritage, and functionality, making them enduring status symbols for discerning collectors and professionals alike.
