The rectangular Ref. 2441 with sculpted lugs is also known as the “Eiffel Tower” due to its fascinating case geometry. Beneath its snap on caseback, the timepiece is powered by Patek Philippe's Cal. 9'''90, a tonneau-shaped mechanical movement with 18 jewels. The Ref. 2441's silvered matte dial is finished with an interesting mix of applied gold baton, dagger and Roman numerals, with a subsidiary seconds dial.
