Titanium perpetual calendar watches

The Titanium Field Guide lists 23 titanium perpetual calendar watches, from $595 to $232,000, from 10 brands. Every entry is verified for titanium content, sourced against the maker, and dated.

Titanium perpetual calendars track the date, day, month and leap year correctly for decades with no adjustment. It is the most horologically ambitious end of the titanium catalog, and the light metal keeps an otherwise serious watch comfortable.
