This one ...

 

I'm starting to warm up to slowly.


It was not love at first sight. Didn't quite like the Venn diagram style dial, and reading the time is probably a bit difficult. 

But, later found the historical connection with Seyffert pocket watches, and find it quite unusual and interesting.

[Seyffert pocket chronometer, from ALS website: "In 1799, German natural scientist Alexander von Humboldt embarked on his legendary expedition to Latin America. One of his most important scientific instruments was a chronometer built by Saxon precision watchmaker Johann Heinrich Seyffert. Its precise reading of time helped Humboldt calculate the co-ordinates of his locations and perform many scientific measurements. In the interest of good legibility under poor light conditions, he chose a model whose displays of hours, minutes, and seconds were separately arranged in a triangular geometry. This so-called regulator dial also graces the RICHARD LANGE TOURBILLON „Pour le Mérite“ and the RICHARD LANGE PERPETUAL CALENDAR “Terraluna”, for example."]
