Slide Rules You Wear
and do other odd stuff with...

* Not every slide rule is a lofty and significant piece of scientific equipment, some are just for fun, and some you wear one place or another. There are slide rule watches, cuff links, moneyclips, lighters, keychains, and tie clips. These items add some spice to the process of collecting that might otherwise get pretty stodgy and dry.

* 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.

* As we get pictures of these various items, they will get added into the archive for your pleasure. If you have pics or more information to provide, please send them to me HERE, and I will add them in. Thanks to many who have furnished pics to fill this archive, espeically Craig Kielhofer, who searched out many examples, and provided photos of all his own items.
