Seiko S143 - 300-Lap Memory Stopwatch with Printer Port

The Seiko S143 is a professional 300-lap memory stopwatch built for coaches and officials who time large groups and want the option of printed results. It records split and lap times to 1/100 of a second, stores up to 300 of them segregated by event, and connects to the Seiko SP12 printer for on-site paper records. With a large three-row display and water-resistant build, it's a reliable workhorse for track, cross country, and swim programs.

Key features & specs:

• Measures up to 10 hours to 1/100-second resolution
• Split/lap time measurement with store and recall of up to 300 times
• Memory segregated by event, with multiple-event memory
• Memory recall during operation — review times while still timing
• Connectable with the SP12 printer for on-site printed results
• Large three-row display panel; time and automatic calendar
• Battery-life indicator and water-resistant construction

Coach's tip: the 300-time, event-segregated memory lets you clock an entire meet or training session without stopping to write anything down — then recall or print every split afterward. Pair it with the SP12 printer for instant results tapes. Care: keep it dry despite the water resistance, store in your meet kit with a spare battery, and check the battery indicator before each event.
