I believe you are correct, sir, but simply because of grammatical errors or too-specific language. You assert that "a pot of boiled watches will never tell time, not even once a day."

1. A pot of anything will never tell the time, since pots do not tell time. If this is what you meant, then the "of boiled watches" is irrelevant and unnecessary information.

2. "Never" is an absolute term, and finding even one exception disproves your entire statement. I have several exceptions.

3. If you meant that the watches within the pot will never tell the time, you are sorely mistaken for three reasons.

3A. One cannot boil a solid (such as a watch) as the passing from solid state to a gaseous state is referred to as sublimation. Therefore, you must be using the term "boiled" colloquially to mean "subjected to heat in boiling liquid" (OED.com). Boiling liquid would not affect the mechanical parts of the watches, though it might stop a watch from working properly (which would still be correct once a day).

3B. Waterproof watches would still work properly in liquids with low enough boiling points (such as water). The waterproof watches will not stop working until the pressure becomes too great (which would only occur in extreme depth, which is extremely unlikely in a "pot") or parts of the watch begin to melt, which would not occur in water, since 100 degrees Celsius will not melt very many solids (http://metals.about.com/b/2005/09/15/free-melting-point-chart.htm).

3C. Watches with all of their display parts ALWAYS tell the time (not always the correct time), even if they are stopped or wrong. You should have specified if you were referring to watches telling the "correct" time.

4. If you meant the verb "tell" to mean "acknowledge or understand", as it occasionally does colloquially, then nether the pot nor the boiled watches would ever "tell time." But, this assertion would be obvious and common knowledge and would therefore not fit the category of "aphorism."

Thank you for your time. Please amend this aphorism until it makes sense, logically.

Perhaps by "tell the time" Msr. Butzbach meant that the watches will "convey the current time" - as in speaking the time aloud when someone asks you "Do you know what time it is?"
Also, I am thinking perhaps he meant to say 'boiling' watches - as in 'watches being boiled in water'(the pot implying a stove and household cooking) instead of 'boiled watches', as the original text makes no sense at all.
If we assume both points, I think he is correct, as I am sure that the level of pain a pot of boiling watches would be feeling would most likely make it impossible for them to discern the proper time - not only that but the steam would probably fog up their displays and make it very hard to read the time as well.
This reminds me of a joke.
Q: What will a boiling watch say when you ask it "What time is it?"

A: TIME TO GET ME OUT OF THIS BOILING WATER!

...in response to and in aid of my ramblings.

However, what you both (gentlemen you may be) fail to realize (the vicissitudes of your respective analyses notwithstanding) is that the lyrical, poetic rhythms and cadences of my so-called "aphorism" is simply meant to call to mind the gentle convection of the womb. It is there that humanity is at its most sacrosanct.

To wit:
Do we not all share the indomitable human spirit?
