Watch display type is the user-interface fundamental split. Analogue watches (with hands) run a mechanical or quartz movement, and the dial shows hour, minute, and second hands. About 95% of traditional watchmaking sits in this category. Digital watches show numbers on an LCD or OLED — Casio entered the category in 1974 with the Casiotron; today the G-Shock DW-5600 is iconic. Ana-digi hybrid combines both — an analogue dial plus a small digital subdial.
Analogue's advantage is intuitive reading — hand position reads 'half an hour from now' fast, while digital numbers read a specific time. Mechanical analogue carries horological tradition plus craftsmanship plus zero battery dependence. Digital brings multi-function features (stopwatch, alarm, world time, calculator). The G-Shock DW-5600 with 200m WR plus 20-bar shock plus a 7-year battery is the pure tool watch.
Ana-digi (analogue-digital hybrid) combines both worlds. The Casio AE-1200 'Royale' at £40 is the entry — analogue hands run the 12-hour indication while the digital LCD shows secondary time, alarm, and stopwatch. The G-Shock GA-2100 'CasiOak' has the ana-digi structure under modern iconography. The Tissot T-Touch is the luxury tier — an analogue dial plus a touch-sensitive sapphire crystal LCD subdial. The smart watch (Apple Watch, Garmin) is the technological evolution of ana-digi; an OLED full-colour display with sensors and connectivity.
