BREGUET, master in the art of dial composition, and genius in the creation of complications, so much to choose from...
Tourbillon, equation of time, perpetual calendar, moonphase, minute repeater, rattrapante chronograph, gmt alarm, regulator, small second, ect... so much to choose from.
One of my favorite complication is the GMT-Alarm ref.5707 AKA "reveil du Tzar".
I love it for it's 2 time zones, useful when you are very international, and also for it's simplicity.
Setting up the alarm on this watch takes a couple of second, it is so simple and fast, that even a mobile phone or any other devise can't beat it.
Proof that a mechanical time piece can still have a useful and practical place in this modern world.
And it does make the world a lot more beautiful and enjoyable too.😉
