Frequently asked questions

Is the U-Boat Classico Ceramic Chrono 48mm nickel-free?

No. At least one part that touches the skin is steel, usually the caseback or the clasp, and steel carries nickel, so the guide does not list it as nickel-free.

The case is black ceramic. The guide has not yet confirmed it on the maker's own page. The caseback is ceramic (sapphire window).

What size is the U-Boat Classico Ceramic Chrono 48mm?

The case is 48 mm across. It is water resistant to 100 m.

How much does the U-Boat Classico Ceramic Chrono 48mm cost, and is it available?

It is no longer made, so the only way to buy one is used.
