The Rolex Datejust reference 6104 is one of the rarest Datejust references as it is one of the rare models that came with a smooth bezel. These early series are recognisable be the Swiss Made signed on the dial as well as the correct cut-off Rolex crown logo on its dial. Featuring the much less prominent pink gold case and still fitted with its original dial (with the word officially written in red), hands, bezel and a clean and deep punch mark on the case, these rare and early Datejust are still extremely good value considering their rarity.
