Swiss watchmaker Audemars Piguet and the Tony Awards have partnered for "Time to Give," a benefit for Broadway Cares/Equity Fights AIDS that will feature one-of-a-kind watches bearing the signatures of such Broadway stars as Antonio Banderas, Kristin Chenoweth, Alan Cumming, Edie Falco, Whoopi Goldberg, Kelsey Grammer, Sean Hayes, Neil Patrick Harris, David Hyde Pierce, Hugh Jackman, Catherine Zeta-Jones, Jay-Z, Jane Krakowski, Nathan Lane, Angela Lansbury, Cyndi Lauper, John Lithgow, Sienna Miller, Bebe Neuwirth, Cynthia Nixon, Chita Rivera, Anika Noni-Rose, Liev Schreiber, Meryl Streep, and Vanessa Williams.

A highlight of the event includes a men's and women's Royal Oak Offshore 57th Street watch each signed by Daniel Radcliffe and Scarlett Johansson. Each watch in the collection features the celebrity's signature visibly recreated on the back or side of the timepiece.

The benefit will culminate in a live, invitation-only auction (conducted by Christie's) and cocktail reception at New York's Four Seasons Hotel on Monday, May 17.

Opening bids starting at $2,500. The collection can currently be viewed and bid on by the public at www.charitybuzz.com/audemarspiguet.
