Only Watch is a stylish biennial charity auction filled with one-off timepieces created by the world's finest watchmakers with proceeds benefiting Duchenne muscular dystrophy research. This time around, Tudor stepped up in a big way with an all-black-everything version of their popular Black Bay timepiece.

The watch trades its 41mm stainless steel case for a ceramic version that's complemented by a matching matte black ceramic bezel, PVD-treated crown, PVD-treated caseback, and black alligator leather strap finished with a matte black PVD-treated clasp. It's powered by Tudor's in-house MT5602 movement with a special matte black PVD-treated rotor to really complete the stealthy look. 

Set to hit the block on November 9 in Geneva amongst dozens of other special editions, expect this to go for way beyond its meager $4,500–$5,500 estimate
