The company, the had wisely piled stock in the good period, continued to invest in research, testing new materials and new filling systems, up to the realization, in 1933, of the wonderful [[Vacumatic]], with the arrow clip drawn from ''Joseph Platt'' (patent {{Cite patent|US|D088821}}, who has since then become the company symbol) with a transparent tank thanks to the [[Sistemi di caricamento#vacumatic|new filling system with the same name]]. The new pen reported the company at the top of the market.

Nel [[1939]], seguendo una tendenza inaugurata dalla [[Sheaffer]] con il suo ''[[White dot]]'' e seguita poi da altre marche, anche la [[Parker]] adottò un simbolo per indicare la garanzia a vita, ponendo in testa alla clip delle proprie penne il ''[[Blue diamond]]'', un piccolo rombo smaltato in blu. A differenza di quanto accaduto per le altre marche il simbolo fu introdotto in ritardo ed ebbe vita relativamente breve, andando a sparire dopo alcuni anni.

In [[1939]], following a trend initiated by [[Sheaffer]] with his ''[[White dot]]'' and followed by other brands, also [[Parker]] adopted a symbol to indicate the lifetime warranty, putting in the head of their pens clips the ''[[Blue diamond]]'', a small diamond in blue enamel. Unlike what happened for other brands the symbol was introduced late and for a relatively short period, going to disappear after a few years.
