IWC Da Vinci 3754 Rattrapante Perpetual Calendar: So deliciously outdated.
And so deliciously charming.
Here are the rose gold,

And the two platinum versions.
I went for the platinum silver, some 20 years ago, and sadly lost it. But if I had to do it again, I would go for the blue, which adds an extra touch of fun and freshness which is very welcome.
Best,
Nicolas
