The timer works. I was doing it wrong, sorry. I was pushing all the keys at the same time. When I push RCL and after CHS-7-8 it works.
In the other hand I insist, it is a HP-45 and the model doesn´t appear in the front label :-)

I have never seen an HP-45 without the timer function, and I have played with some very late model ones.
I would suspect that your machine either has had the front label replaced from a '35 or an old style label was left hanging around in the HP parts bin and was used when the machine was built. I have seen quite a few flukes like this (particularly very early in the production cycle) like HP25C machines with HP25 front labels, or keyboards that did not have "Continuous Memory". I also have an HP25 with an HP22 front label (known to have come that way from the factory).
