My chunky Italian Giuliano Mazzuoli Manometro. I was all set to go Panerai when I was in Florence last winter, but then my wife discovered a designer/watch company headquartered just outside of Florence and who has the most interesting life . . . Descends from clock makers, has a business making high-end pens, former Alfa Romeo race car driver, and seemingly a very well connected and beloved artisan in Tuscany. Very low annual production. Tuscan leather. I like a story. This watch is the largest in my collection by far and it weighs quite a bit (including memories and the fact that my wife helped me discover it).
