Dear Oliver,
This year, 2015, is my Gerald Genta year. I will be wearing 365 days of four creations of GG: AP 15202, RO QP, Nautilus 3712 and 5711. First I will wear each watch a bit longer time and follow also their time keeping. After each session I will make notes and compare the watch with the one I was wearing earlier. This stage will take half a year.
I have always three wathes on a winder next to my bed and the one I was wearing one the previous day next to these three. Every morning I will pick up one out of these four and mark it to my diary. In the end of the year I will see which one was my favourite.
I will also take a lot of pictures during the year and always travel everywhere with at least two of these watches.
Sometimes in January 2016, I will try to give my verdict: simple RO or Nautilus or complicated RO or Patek.
I started my journey on 1st January @ 00:00 with my 3712. I guess it's a decent replacement of 5712... On 20th January I changed to 15202 and in about 10 days I will change again.
I started this "project" for the simple reason: I can't really tell which watch is my favourite steel sporting watch. For sure it's one of these. I hope that one year of wrist time will give a clear answer. Another good reason for this project is that my other watches can rest and those will probably feel like new love affairs in 2016.
In other words; I accept your challenge.
Best, Kari
