My love for the Rolex Big Bubbleback continues with this lovely Rolex 6105 in 18k gold from 1960. The indices are ‘arrow-markers’, and the hands are beautifully elegant ‘dauphine” style - even the fluting on the bezel (coin-edge’ bezel) just seems a little more subdued. This is perhaps the last batch of the Rolex Datejust using the semi Bubbleback movement and it is without the cyclops crystal but with the rudimentary Datejust wording on dial. It has the lovely classic red and black calendars.
Besides having a nice bezel, it has a nice Red Datejust wording on its dial. As per my direction for 2025, I shall focus on upgrading and I have traded in some watches for this. I have always thought that the Rolex 6105 only comes with bi colour gold and steel but it has the 18k version as well.
