Adding, or better said, building a collection, is a fascinating thing.
Reducing a collection to the essential is as fascinating, IMO, than building a collection.
It obliges you to re think it all, to go to the Essential.
In this case, taking one among all the complications, like a GMT, an Alarm, a World Time, a Chronograph, a Minute Repeater, an 8 Days Power Reserve, a Perpetual Calendar, a Chronometer, a time only, a Tourbillon, is a very attractive solution.
Now, even more difficult is keeping only one.
That is what I call the holy quest.
Something irrealistic, but so tempting, at the same time.
In my case, this watch doesn't exist, yet.
It would be a Water Resistant To 100 meters, Alarm, GMT watch.
A watch I could bring with me in any part of the world, I would wear in any occasion, for all the styles of my life.
But, on another side, I perfectly understand that this passion may be tiring, and that reducing / summing to only one watch is a tempting exercize.
Best,
Nicolas
