New SS GMTII worth $1,500 over the SD?

[dnnaudio]

A few weeks ago after days of pondering I was set to purchase an SD from my AD. However when I was ready to go for it I learned they were no longer on stock, especially the one I tried on. And other ADs in the country did not have it either.

Since then i've seen the many praise and pictures of the new SS GMTII at this forum and have become undecided between the two. Yesterday I learned that fresh stocks will be coming in soon which includes both SD and new SS GMTII.

In here the new GMT is US$1,500 dearer than the SD. To those of you who have seen and worn these watches side by side do you feel that extra $1.5T is worth it regardless of watch tool functionality? Thanks.
