Timex Ironman Essential 10 vs Timex Ironman Triathlon Classic 30

Both are Timex Ironman quartz watches with 100m water resistance, acrylic crystals and 100-hour chronographs. The Essential 10 is the better training watch: a 42mm case, 10-lap memory and a 24-hour countdown timer suit interval work and long sessions. The Triathlon Classic 30 is smaller at 38mm, carries 30 laps of memory and a rated 6-year battery, so it fits thinner wrists and people who want more lap storage. Owners of the Ironman line consistently praise the light resin case and simple buttons; the acrylic crystal scratches more easily than glass on either watch.

• Choose the Ironman Essential 10 if you want a larger 42mm face, a 24-hour countdown timer for long workouts, and a watch you can wear in the pool or shower.
• Choose the Ironman Triathlon Classic 30 if you have a smaller wrist, want 30 laps of memory instead of 10, and value a long-rated battery.
