Watch holds up in saltwater!
Color: Black/Gray
I bought this watch to use for my trip to the Galapagos Islands. I read two reviews that the watch does not hold up in salt water. I went snorkeling in the ocean 6 times, about 45 minutes each time. The watch did not leak. I did take precautions by keeping the watch under my rash guard and lowering myself slowly into the water. I also rinsed off my watch each time I snorkeled. I also bought this watch for the multi time zone feature by saving the time on the west coast, east coast and Galapagos time since I cannot change the time on my Fitbit until I land in an airport. I did not use any other features of the watch because I generally use my phone or Fitbit for an alarm or timer. The only complaint I have is that Timex now discourages changing the battery by the consumer. I changed the battery myself on my old Ironman watch. The new Ironman watch is fitted with triangular head screws. So I will have to purchase screwdrivers with triangular heads when it comes time to change the battery.

Reliable and durable, even in harsh conditions
Color: Black/Gray
This watch has served me very well. From Arctic waters to long distance races, it has held up to everything except one task I asked of it, which was my fault.
This watch can handle repeated free dives to 12 ft deep. It cannot handle scuba diving at the same depth for an hour straight without needing to have the battery shorted to reset it.
It fits well, lights up consistently and brightly enough to read without being blinding, keeps accurate time, and generally does everything I want it to.

The Ironman logo is a serious distraction.
Color: Black/Black/Digital Neg Display
A wonderful watch, with one serious problem: for me at least. The big Ironman Logo at 9 O'clock position is a very confusing element in this otherwise nice design: it competes and completely overwhelms the two Hands read-out. The Logo can give you misleading time: because one confuses it for the Minutes Hand. In a hurry, one is bound to make such mistakes -- call it a human error, but this one can have serious consequences, i.e. reading the wrong time.
I have a couple of digital Ironman watches, and Timex does a great job with their usability and quality. This watch is of very high quality too. I love the dual display, and it is very practical.
All this watch needs is a removal of the white Ironman logo. That would also make reading the digital readout easier. Please leave the Minute and Hour hand to their exact shape/design -- i.e. don't mess it up. This watch has the potential to be a much more user-friendly watch. I hope the next gen has a simple dial with hopefully even an easier digital readout. Please color the 'Start' Button Orange. I love the Orange Seconds hand.
Overall: Size is good. Strap is good. A very good concept digi-ana. Very practical.
