But first let me give a little back story on the brand name and logo. Typsim is a funny, well not that funny - more ironic play on architectural shorthand for “typical” and “similar”. The logo associated with the brand is a simple circle with a horizontal line thru it - basically an architectural reference bubble. While it started as a folly on architectural graphic standards, I like the name and simplicity of the logo. I believe the logo elicits other ideas and references - which gives it some viability.
Point of that quick aside was to help explain where the inspiration for my 12 lume index experiment came from.
I slimmed the crown by 1mm, cut 4mm off the lug-to-lug, scaled the 6/9/12 lume plots down a bit, revised the 12 plot shape, and continued to develop the typography.
RE: Chronometer. The term is not internationally registered nor prohibited from use. If I understood my research, it’s not necessarily trademarked in Switzerland but there is a gentlemen’s agreement in place regarding its use. Besides that, the term chronometer was invented in England...but maybe that’s another thread.
I intend to have the watch tested and certified by BESANCON Observatory, an internationally recognized ISO3159 testing agency. In passing that test the watch will be certified to perform as a chronometer, hence my plan to use the term on the dial.
