Huh
I'm confused, are you saying that watches don't use Tritium
Not to argue, but I'm confused by what your saying. However I'm no Nuclear Rocket scientist

Because tritium in particular is an integral part of certain thermonuclear devices (though in quantities several thousand[citation needed] times larger than that in a keychain), consumer and safety devices containing tritium for use in the United States are subject to certain possession, resale, disposal, and use restrictions. Devices such as self-luminous exit signs, gauges, wrist watches, etc., which contain small amounts of tritium are under the jurisdiction of the US Nuclear Regulatory Commission, and are subject to possession, distribution, import and export regulations found in 10 CFR Parts, 30, 32 and 110. They are also subject to regulations for possession, use and disposal in certain states. They are readily sold and used in the US and are widely available in the UK and are regulated in England and Wales by environmental health departments of local councils. Tritium lighting is legal in most of Asia and Australia.

Just on google search alone I found over 50 watches with Tritium painted faces.
Again, I'm not saying that this poses a deformed baby issue because the quantitiies are small and Tritium in small quantities have been deemed as safe.
But the original argument though a little misguided does stand from a certain point of view.
