Filmed on July 27, 2015 (Asian time): 3200-Series buttons. This elevator is also used as a service/freight elevator. This thing is SEVERELY BUSY! JimLiElevators Copyright 2015
This is actually a SPEC Alza because of the grey buttons, flashing arrow and Mitsubishi chimes. (3200 chimes sound more synthetic) SPEC Creces is the white buttons version and SPEC 90 is a common fan term for this kind of OTIS from the 1990s (3200 is 2000s version), plus 3200 only comes with white buttons and doesn't have flashing arrows (which is optional for SPEC Creces/Alza).
Just asking do you know Beijing Foreign Languages Bookstore in Wangfujing? They have two OTIS 3200 (but for some strange reason they are branded as U&E Lianheng) elevators and a Toshiba service elevator at the back. I went there in July 2011 and the employees were a bit grumpy.
