Ty's original post needs some updating. Yellow + blue dial 6139-600X's originally came with red second hands. The JDM 6139-6000 with the Sunrise dial came with a yellow second hand. The 6139-603X JDM speedtimers had orange second hands.
It always possible that during service or repair someone didn't have the correct second hand and just used what they had available.
The second hand is dedicated to the vertical clutch and can not be swapped from one movement to another without broaching it to fit. Otherwise it needs a new hand.
