The humble, ubiquitous yet legendary Casio F91-W – a digital watch worn by virtually everyone from middle-school students to world famous celebrities – utilizes a lot of text on its case that quickly describes its features and controls.
Most of this text is set in Eurostile Extended Regular and Medium. “Alarm Chronograph” is set in the regular-wide Medium weight and the “F91-W” text seems to be using Neue Helvetica Extended Black. The Casio logo itself appears to be in Microgramma, judging from the counter in A. The heavy usage of large, wide text on such a small case makes it very readable and easy to follow the watch’s controls. The watch’s descendants, which mainly fall under the “F-91W Series”, reuse the same case design with some minor alterations.
