Piaget have a rich history of producing some fine and beautiful watches, especially featuring stone dials, as well as stone-set cases. These Piaget pieces are becoming increasingly sought-after as collectors begin to finally appreciate their quality, rarity and value.

This stunning example is a Piaget "Tank" ref. 91505 from the 1970s featuring an original pavé diamond-set tiger's eye stone dial, housed in an 18k solid yellow gold diamond-set case. Inside is the thin, manual wind Piaget 9P calibre movement. The watch is twinned to its original Piaget brown leather strap and gold-plated Piaget pin buckle. 

The watch is an excellent example, with a very well-preserved tiger's eye stone dial which is free of cracks and chips. The case is in very good condition with some light scratches commensurate with age, and has crisp hallmarks and numbering. The glass is free of marks.
