In 1957, the company launched the T-Ball refill, which contained reformulated ink and a textured tungsten carbide writing ball. One year later, the company added an arrow to replace the ball-clip design. The arrow has remained on all production Jotters since then. When introduced the arrow was without quills. Shortly thereafter, the quills were introduced, making the plain arrow models somewhat rare and commanding a premium in the market place. These pens are not to be confused with the 50th anniversary pens introduced in 2004. At some point, the interior diameter of the Jotter was reduced and a new refill introduced. There are two barrel variations, the large diameter version and the smaller diameter version. Some pens have been found with early caps fitted to the later small diameter barrels and represented as rarities. Additionally, there are several cap variations resulting from changing the imprints on the cap. The period from 1958 to 1973 saw many slight design changes, making it difficult for the collector to obtain a representative example of each production specimen. In 2000, the plunger was modified to illustrate the new company logo. This is to be found mainly on UK versions, although a few pens manufactured in the USA have these buttons. In 2004, the Jotter's Golden Jubilee, the company released a number of special editions. The flat button was restored to its original rounded shape that it had prior to 1973 and was imprinted with the number '50' signifying the pen's fiftieth anniversary of production. This button was used for only one year. Several new colors were introduced and the special edition pens were attractively finished in sterling silver and lacquer or a new process, the name of which is unknown. The plain anniversary clips have been seen attached to later barrels, and earlier and later plungers attached to later caps, creating even more variations. Earlier colors have been found with later caps indicating that Parker was cleaning out their old inventory. In 2009 Parker again changed their logo to resemble the older arrow logo. Plungers were revised and they were no longer imprinted with the corporate logo.

With years of experience and innovation, Parker’s commitment to quality has ensured that each pen delivers the best writing experience for when it matters most. This commitment has received royal recognition with Parker being awarded two Royal Warrants. The first in 1962 by Queen Elizabeth II making Parker the official supplier of writing instruments to the Royal Household and the second in 1990 from His Royal Highness the Prince of Wales. There is a series of 24K gold-plated versions with plastic barrels. They have been found in several colors. There is another variation from England that has gold clips attached to stainless caps and plastic barrels with chrome tips. These are in addition to the traditional versions with a gold clip and tip referred to as the 'GT' or Gold Top. The factory also issued a number of variations using left-over inventory.

If a production run called for blue and the staff had been running gray barrels, the last of the gray material would blend with the blue, producing a blended color barrel. At one time, the company explored the idea of producing these blended barrels, but the concept was never introduced. In April 2016 Parker significantly updated the line, introducing a new core range and premium range. Both feature metal barrels, in a variety of colours, named after London Underground stations. Both ranges feature a new clip with an updated arrow design, while the premium range complements this with more intricate designs on the cap portion of the pen.
