Wow, Bill, you are going fast in the Patek World. Bravo, mon ami. Very happy for you. On another note, I was on to post something about the Aquanaut... In a slightly different register... ;)
The 5164 is my go-to travel watch for its easy and intuitive GMT function and it’s a very comfortable piece to wear on long flights. Plus you can take it for a swim! Enjoy it in the best of health, my friend! ...
