The Royal Oak Offshore 26195ST is a limited edition of 200 pieces created in 2009 in collaboration with Japanese kickboxer Masato Kobayashi (魔裟斗). It features a stainless steel case. The black/red dial is inspired by his fighting colors. At 1:00 the dial features a diamond-set three, which is said to be Mr. Masato's lucky number. The 14 found at 2:00 is that of his wife.
