I'll have to disagree with you on the TI failure rate (you sort of zigged and then zagged). The TI's have an extremely low failure rate, imo lower than the Hughes by a small margin. They (TI) are very well sealed. The real problem with a TI is that the button contacts are thin, flimsy, easily bent little pieces of "stuff". And of course, a fair number are sold as none working by people who don't understand that most TI movements don't start
actually running and moving forward in time until you have gone through the setting process once. Like the Litronix, TI wanted to be able to ship with batteries in, yet not have the batteries getting drained. The show time when you press the command, but the clock isn't running until it has been set.

I've bought dozens of both from people claimed "it shows the time but the time doesn't change."
