16800 second hand length?

[dere]

Hello!

I am little confused about Submariner 16800 second hand lengths. How many different lengths are there?

For example from this thread: http://www.rolexforums.com/showthread.php?t=377473


Lume spot of second hand is over the "square" index


Lume spot is not even near the square index.

Also the total length varies, some have second hand as long as a minute hand and some have little bit longer second hand (hand reach the minute markers).

Sorry for my bad english.
