I finally visited the GO boutique in Singapore few days ago.
A small and cosy boutique with very warm and knowledgable staff.
The watch that seduced me the most in the boutique is the GO Senator Perpetual Calendar boutique edition. 
The case is in steel and that blue dial is simply amazing! It's not like any other blue dial I have ever seen.
I love high complications in steel cases and especially with blue dials and this ticks all the boxes.
Some other interesting parts of the boutique I captured. My phone settings had some issue that evening and many of my photos had to be deleted.

Swan neck door handle. How cool!
Took this pic as I was walking off so didn't ask the boutique staff about this watch. Seems like it can read multiple time zones - anyone knows this watch?
I am so new to GO. I didn't know they were related to Lange initially . So much to research and read!
Cheers
