Features
Everything you need in a boxing timer.
No filler. Just the controls that matter for round-based training.
🔔
Bell Sounds
Authentic bell at round start, round end, and a warning bell at the 10-second mark — so you never have to watch the timer.
🟠
Fight / Rest Colour Modes
The display shifts to orange during rounds and dims during rest — readable from across the gym without squinting at numbers.
⏳
GET READY Countdown
A short countdown before the first bell so you're in position and gloves are up before the round starts.
⏸
Pause & Resume
Stop the clock mid-round and pick up exactly where you left off — useful for injury breaks or equipment adjustments.
