The origin of the Sinclair Oxford was somewhat unusual. In November 1974, Sinclair, along with several other companies, was asked to design a table-top calculator for Gillette, who were at the time tentatively entering the consumer electronics market. Sinclair invested a lot of time and effort in the project but to no avail: Gillette got cold feet and decided instead to put the whole project on hold, nervous about economic and pricing uncertainties. Although the resultant calculator was eventually released as the Gillette GPA, it was a short-lived product.

The Oxford 300 was a scientific model with a limited number of functions (such as sin, cos, tan etc), which at £29.95 + VAT set a new price level for this type of calculator.
