But it was only in 1925, when the construction of the factory in Via degli Orbi was completed that ''Officine Meccaniche Armando Simoni'' was born, and the acronym [[OMAS]] become the brand under which fountain pens were marketed. The first [[OMAS]] major model was the ''[[Modelli iniziali OMAS|Penna del dottore]]'', patented in 1927. It was a [[lever filler]] hard rubber model having a compartment inside the barrel that contained, in addition to the filling mechanism, a thermometer to measure temperature, kept separate from the rest by a metal partition. In the same year [[OMAS]] got another patent for the metal joint used for the realization of desk pens, for which the company was one of the main Italian producers.
