My favourite aspect of the 5817 has always been the subtle wave theme across the rotor, deployant, crown guards, and guilloche dial. The designers achieved this while still keeping the classic Breguet fluted case. Lovely stuff; thanks for the reminder, Jack.
I think the Marine is a good suggestion for the clinical environment, Rory. You will require a watch with an easy to read second hand (and possibly a date, as the long shifts can get a bit disorienting). Those early years as a doctor are very memorable and the watch which accompanies you is an important decision.
Best wishes for your career.
