I've seen this kind of pictures several times in WRUW and in Omegaforum blog, I wonder how they could do it. This morning somebody teach me through whatsapp. Turn out very simple thing to do with simple free mobile apps.
This maybe my first post, I took this pic whilst visiting the tourbillon dept at Omega in Switzerland.
Oh wow, that watch second from the foreground is the cool one of the bunch. Possibly the most subtle yet special tourbillon wristwatch ever made by any brand. Welcome btw!
