Speedmaster Professional 750

[Simonja]

Hello,
I am usually in the Rolex forum but I have recently been fascinated with looking at Omega models, especially the Speedmaster etc. A lot to learn I fear.
I am partial to gold (I know I know) and have recently seen on one of the known sale sites a Speedmaster Professional 750 gold from 1995 limited edition number xx/250.
Can anyone pleas give me any insight into this piece, I.e. Why it was manufactured, or for what anniversary etc.
I appreciate that Speedmaster have a long and varied rich history and indeed it was the launch of the CK2998 recently that caught my eye to Omega.

The code is 319 450 00

Any information would be grateful and helpful

Best
Simon
