Which highlights the great balance achieved by rolex with the explorer. I'm more on the tool end pf the spectrum but a few left field options such as the revised LV Tambour, Hermes H08, Breguet Marine (not in love with the way they did lumed indices but the wave pattern on the blue dial is stunning in person). A bit older I would consider a Blancpain Leman Aqualung, big date or regular, or even the flyback chronograph all of which are fairly easy to find. Good luck!
