New to the forum but not to the Vintage HP world + HP-01

[Massjmo72]

Here some pictures of the full set. It comes with foam inserts and besides all the original paperwork it has the original receipt of sale from HP being an employee purchase, registration receipt and HP service center letter from 12/20/79 were it states that the module was changed. Serial number is low, being 00231 and production code 1912A. The watch is running 2 minutes behind, I don't know if it's because it needs fresh batteries or some oxidation. It looks very good cosmetically, I would rate it at 8.75/10 and the extra papers from the original owner are bonus.
