The present watch is a very rare and probably unique example of the celebrated reference 5513. The reason for this uniqueness of this reference is the engraving on the back highlighting the Licancabur expedition led by Charles F. Brush in 1984. Furthermore this piece is preserved in excellent overall condition.
In one of the expeditions to the world's highest lake in the crater of Volcano Licancabur, Charles F. Brush established an unofficial world altitude record (19,300 feet) for scuba diving in 1984. Licancabur is a volcano located on the border between Chile and Bolivia. The summit is one of the highest crater lakes in the world, and despite air temperatures which can drop to -30 C, this lake harbours planktonic fauna.
