1. Materials is full efficient and reliable


Military-grade circuit board, advanced patch technology, seckill in-line design. Adopting high-quality components, DC power supply is more efficient

2. Simple design but not simple functions

Ultra-simple shape design contains 20 years of rigorous and precise production technology to maximize portability and achieve maximum application with small machines.

3. Metal plastic, Rugged pressure

The selection of sturdy and pressure-resistant hardware material body, thickness is about 2mm. The fuselage vents conform to the airflow principle. Reject all counterfeit materials and refurbishment.

4. Super movement, Multiple protection.

The small model has a big effect. Compared with the large-volume power supply, it has the same protection function and performance. The performance linear power supply is higher, overload, over-voltage, over-current, current-limit, multiple protection, and be relieved to use.

Used Watch?
Color: Black/Gray/Digital
The watch is great but the watch had been worn. The protective film was removed and it was loose in the watch box and not on the plastic holder. I bought a new watch not a used one. Joe

My last Timex and why.
Color: Black/Gray/Digital, Color: Black/Gray/Digital
New edit. Upon further reflection, I’ve only had, a couple of exploratory years with Swatch excepted, Timex watches. My first one was when my mother replaced the Chicita Banana “tickity tock” sticker with a real Timex wind up watch before my first Cub Scout camp. In addition to many other Timex products, I’ve had these Ironman watches for the past 25+years. Usually the band wears out and can’t be replaced after three or four years. This particular watch fell apart less than six weeks old. It wasn’t hit by impact. It just came apart while I was driving down the road. I wonder if they’ve changed their manufacturing process. See photo for details. What is truly infuriating is that rather than replacing it, because it is truly a warranty issue, the told me to ship it to their offshore repair facility (which could take 3-5 months) and pay what might be half the value of the watch. Things happen, but the intentional friction they have created to avoid their obligations borders on malpractice and speaks to their indifference toward customer experience and subsequent lifetime value.

As expected
Color: Gray/Gray/Digital
Just an old school digital timex. Tried and true. Has both 12hr and 24hr function on the time setting. Has a standard stop watch and timer. The battery is great, just as it always is on a timex. Good water resistance and very easy to use. Overall very good watch for the price!
