Good eyes! But you missed the stars of the evening - a 5213G minute repeater perpetual calendar, the 5370P split seconds chronograph and a Simplicity!. They were the purpose of the gathering...
There are two watches with a blue dial - one is a Panerai Equation of Time (I don't think you mean that) and a de Bethune DB25 jewellery with diamonds depicting the Geneva sky and 44 blue baguettes around the bezel. It is mine 
The GTG took place in Hong Kong where I am based - my overseas dealer decided to hand deliver the 5370P to me and wanted to treat my collector friends to dinner. Next time we will invite you, if you would like to attend a similar function 
Best
