Makers of this type of slide rule were usually makers of conventional items, who then decided to add a 'slide rule-ized' version to their line to interest engineers and similar techno-types. Watchmakers included Seiko, Pulsar, Breitling, Citizen and Selectron, and Breitling, Seiko and Citizen still make numerous slide rule models today, mainly for pilots and race car drivers. Slide Rule tie clips and cufflinks were made by Swank, and some additional makers that have been hard to identify, since the orignal packaging is now long lost for many of these items.

At least K+E, Pickett and probably other slide rule makers had custom tie clips made for them as promotional items, usally for their own sales staff. These are fairly rare items, and seldom seen.
