It is early and later version. I would say the evolution of the Nina configuration is something like this
1) earliest execution (1.1 execution), applied logo dial, thin sub hands, cal 130
2) early execution (1.2 execution), same as above but cal 85
3) 2nd gen early (2.1 execution) applied logo dial, baton subhands, cal 85
4) 2nd gen last (2.2 execution) flat logo dial, baton sub hands, cal 85
