How SensorSafe™ Works:
Originally developed to help prevent the rising number of infant hot car deaths, SensorSafe will chime through the installed vehicle receiver to alert when a child is still secured in the back seat after the car has been switched off. This reminds the caregiver to act quickly, but if the child is still secured after several minutes an alert will be sent to the caregiver’s cellphone through the downloaded app. If the situation is still not remedied, the designated emergency contact will receive an alert with the GPS coordinates of the vehicle’s last known position. This state-of-the-art safety technology is designed so there is no need to reinstall each time you drive - just keep the receiver plugged into your car’s OBD port to drive with that extra peace of mind.
- Chimes through the installed vehicle receiver if child is still secured in the seat when the car is switched off
- Alerts through the caregiver’s cell phone if the child is left behind in the vehicle and then alerts the designated emergency contact if the situation is still not remedied
- Emergency contact receives GPS coordinates of the vehicle’s last known position
- Alerts through the vehicle receiver and caregiver’s smart phone when the child has unbuckled themselves while the vehicle is in motion
- Monitors the back seat temperature to alert through the vehicle receiver and the caregiver’s smart phone when the back seat appears to be too hot or too cold for the child’s comfort
- Provides warnings to the caregiver when the child may have been seated for too long and needs a break
- Receiver plugs directly into your car’s OBD port and syncs with the caregiver’s cell phone
- Only one install needed if receiver is kept plugged into vehicle’s OBD port
- Helps to prevent misuse by providing guidance on installation, how-to videos, FAQ’s, direct link to customer service and more through the SensorSafe app.
- App can monitor up to 16 chest clips on a single platform
- App download available for Android and IOS
- Anti-rebound design reduces car seat rebound movement by nearly 30%

Reliable watch, bad shipping
Color: Pink
I have had a couple other Timex watches. My 1st lasted many years before it quit working. This watch is my 3rd. My 2nd Timex still works but was smaller than I prefer so I bought this one. I'd have given this one 5 stars if it had arrived on time and not had made my subscription order arrive late as well because my items ship to arrive on a set day. My auto ship happened to be when I ordered this watch. I was given a tracking # for USPS at first, to arrive on October 27. Then got notification it would arrive the 28th, THEN got an email saying November 2nd and coming by UPS. It arrived 4 days after it was supposed to. The watch is good, but the shipping was not.

Nice looking, easy to read, comfortable silicone strap, hard to buckle.
Color: Black
This watch has all the features other Ironman watches have plus a 100 lap interval timer. The interval timer is possibly the reason this watch is slightly more expensive than the other IM variants with the same size and general appearance. I find this watch to be nicer looking when going out to dinner than the more common multi-colored IM watches, though most of the functions are available on the others.
My previous Ironman watch had a resin strap, which was somewhate stiff when putting it on. It was comfortable enough wearing on the river, but later in the day I sometimes took it off for comfort. This watch has a soft, stretchy, more comfortable silicone strap, that, sadly, is hard to buckle and tuck-in.

Longtime Ironman Wearer -- I Hate This Watch
Color: Black
I've worn the old Ironman 100 Lap Watch for Years
I would still be wearing those watches if the Indigo on them didn't consistently fail.
My main requisite is large, easy to read digital display, and the ability to turn the Indiglo on 20 seconds a day once or twice to see time in dark.
If I could have found a simple watch with a large display made by any other reputable manufacturer I would have bought it instead. I have truly come to dislike Timex because their Indiglo fails so consistently, on (5) different Ironman's I've owned. Doubt this one'll be any better, viewing it a disposable purchase after a year. Unsurprisingly, Timex is an American company, all marketing no quality, and yes I'm an American, looking at something Casio Seiko, Swiss or Japanese made. They get fundamentals right in terms of quality.
The band on this is redesigned. Grippier. Tougher to adjust or put on, but more apt to stay on and not slide once on. I'm used to the old band, don't love or hate this new one. I will usually take my watch off while typing for a long time, not as easy to do with this, not a dealbreaker, can see the sense in making a swimming and exercise watchband a bit tougher.
I hate the branding on this watch. Bright red Ironman logo on both ends of the band near the watch. Even worse is the Timex and Ironman words ATOP the glass on the watch. This means they throw shadows down onto the watch face below the glass. This effect gets even worse with the magnification underwater. Inexcusable design flaw, simply so some corporation can self-advertise its products. The combination of these two sets of branding make the watch look cheap, gaudy, and inappropriate for any remotely formal wearing. This would not have been the case if it was understated in color scheme. Without the two red marks on the band, and the absolutely moronic decision to place the branding on the watch glass, you have something understated you could get away wearing all the time. Not with the branding. There are also two lines running horizontally above and below the time. I hate these when I'm looking at it underwater. Haven't tried the lap functions yet, I usually open lake swim, maybe the lines help with that, but for my use I hate them.
I'm 6'4" tall, people complain the watch is big, it feels to me if anything a bit undersized or the proper size, others may find it big. I would rather have a slightly larger size with bigger numbers.
Biggest plus is time SUPER easy to read. I'd love to be able to turn date off and only have time display and nothing else in some mode. I don't need to check the date 6 times a day. Love to have mode where I press one button, upper left say, and date shows for five seconds or something.
Indiglo about the same as old big Ironman 100, excellent--when it doesn't break which it almost always does. I have many of these watches where the time still shows but Indiglo never works, Timex themselves admitted to me this is a known problem.
The rounder face, versus rectangular, better looks, but wonder if it is optimal way to make most readable.
I would pass on this watch. I have always liked Ironman watches, but the branding is so bad, glass especially, and the absymal quality of Timex Indiglo, are unacceptable.

Cool & functional
Color: Pink
Attractive watch. Simplistic, yet cannot understand everything without not having instructions. Watch did no come with instructions, which became hard to figure out all its functions.
