The timer would run on a solid core, no-frills design: a 10‑inch LCD screen, single button, and a 1‑second increment dial. The code runs a real‑time clock, so the timer stays accurate regardless of power hiccups. It would store presets for 5, 10, 15, 20, and 30 minutes, plus a user‑set custom value. When you press start, it counts down visibly and emits a sharp, non‑nagging beep at zero, then a short chime if you keep the button pressed to avoid false alarms. A quick swipe of a side lever will pause or reset, keeping the interface clean. The casing is stainless steel with a non‑stick coating so you can wipe it easily. That’s precision, no guesswork, and you can trust the timer to keep you on schedule.
