Comments about Timex IRONMAN 100-Lap 5E231:

i am a runner and i have been running with this watch for years. The best feature of this watch is the split time. Since i run for 9 minutes and i walk for a minute, this option helps me to train the way i want. The only thing that i don't like about this watch is that the strap wears quickly. That is, I have always had to comunicate with Timex in order to order new straps.

  • Q:

    Is it safe to use this watch while swimming? It says that is up to 100m water resistant

      With watches being water resistant and not water proof, Its hard to be 100 % sure of how it will hold close the recommended water resistant depth. If it doesn't stay completely submerged and not close to those depths, its safe to say that it will withstand swimming.

      To change the time zone, simply hold the SET/RECALL button, then press the + or – button to select Time Zone 1 or 2. Then press the NEXT button to select hours and use the + or – button to change the hours. Press NEXT again and use the same procedure to change minutes and seconds.
