Hello,
My no.13 also has not been delivered yet. However, I also know that 10xx has been delivered. Production of the cases is in numerical order, but assembly is most likely not in numerical order and delivery surely isn't in numerical order. However, I have been notified that production and deliveries are still on schedule. Omega is not able to produce all 2012 pieces all at once of course, as they also need their production lines for other watches.
I hope this explains a bit.
If you want to wear it on a bracelet, it is a matter of taste what you prefer. I think a 1171 or 1450 would look nice, as always, followed by a 1479 and then one of the newer references.
