Query regarding the Lange 1 Time Zone 'Singapore' Sincere Limited Edition

I have an opportunity to acquire a Lange 1 Time Zone in rose gold, black dial, with 'Singapore' in place of the usual Hong Kong on the city ring.

While this is by no means a deal-breaker, I would really appreciate it if an enlightened one can shed some light on this. Thanks.

.... The kind folks from Lange were kind enough to look into this matter, and have advised that 30 pieces of each version (one with 'Singapore' and one with 'Kuala Lumpur') were crafted. It is, strictly speaking, not a limited edition as the numbers were ...
