Description
Overview
The Ultrak 420 is a pool-deck stopwatch for swim coaches, water polo bench officials and PE teachers running aquatics blocks. It is water resistant, so splashes are expected rather than feared, and the large numerical display is easy to read while your attention stays on the water.
Cumulative split recording lets you clock each length of a set and review the pattern once the swimmer is back on the wall. Time, calendar and alarm functions round it out, and it sits alongside the Stopwatch Ultrak 340 and Stopwatch Ultrak 495 in the range we stock.
Key benefits
- Record each length as a cumulative split and review the set afterwards.
- Water resistant, so poolside splashes and rain are no concern.
- Large numerical display keeps times readable from the pool deck.
- Counts up to 24 hours for long training blocks and carnivals.
- Arrives with a lithium battery, ready for the first session.
Who it's for
Best for swim squads, water polo and school aquatics, though the same features suit any coach timing repeats on the track. It is also listed under stopwatches & timers for athletics and coaching buyers.
If most of your timing is athletics, the Stopwatch Ultrak 340 shares the listed feature set; our customer-service team can help you pick between the two.
Care, safety and set-up
Rinse off chlorinated splashes and dry it before storing. Covered by our 12-month guarantee.
Frequently asked questions
Can I use it at the pool?

A lithium battery is included.
Can we equip a whole squad?
