The Timex T5J631 Solar Ironman 50 Lap Shock Watch is a great watch! I bought it when i started running and needed to time myself, which I found hard to do with the analogue. The solar power factor intrigued me, and I bought I bought it when I saw it had 100-hour chronograph and 30-lap memory recall.
Its features are: Alarm, Chronograph, fifteen reminders of occasion, Indiglo(light up screen) shock resistant, and Water Resistance (up to 200m). This Ironman watch is great for timing yourself and you will never have to buy a battery thanks to the solar panel, which uses artificial and natural light as a source of energy that recharges its batteries. It has a blackstrap, three alarms and and energy level that will tell you how the solar battery is doing and if you should put it in sunlight. It even goes into sleep mode to save energy.
I have always found Timex watches reliable and after a few months this one is yet to fail me, so I would recommend it as a great watch .
