That won't help. You'll always be behind, late, and taking too long.
signed. All were assembled the same way, using a "reputable" source for the crystals."
A crystal that low maqy be more susceptible to mechanical damage. Normally this should make the resonant frequency go high. If everythng is just barel y marginal for the task maybe the divider chain is missing some pulses.
If it is missing seconds mechanically it would either be constant every min ute, or totally at randon. It would highly be unlikely to lose the same amo unt of time per day. On the other hand if it missed one second per minute i t wold be losing 24 minutes per day. (there are no doubt crazier failure mo des related to the gear train but those are beyond the scope of this text)
Therefore your fault is illogical. As such an illogical solution might be a ppropriate. Have you any firearms at hand ?
Actually, most likely is that the crystal itself was off spec from its manu facturer (low) in the first place and either they do sample checking or in this case no checking at all. Of course checking the accuracy of a clock ta kes a little bit of time (dammit, if I knew more words I could make that rh yme) so therefore they most likely use the hillbilly approach to quality co ntrol.
This varies from "the markup is so damn high we can replace it three times before losing money" (which is what Sears does and the reason I do not buy their tools anymore), to the real hillbilly way of doing it "they are so ch eap, people won't even bother taking them back to the store or shipping the m in".
Given the delicate and intricate nature, as well as the high cost and intri nsic value of the unit, I would guess the latter.
So, I guess a small caliber will do. If you got kids you could let them sho ot it.
Just swap crystals. Really. I actually have solved this same problem several times by replacing the crystal. (I found a transparent clock I liked, in one case.)

One of my Asian clients had a factory that made those things, his were cheap and good, but he complained of cutthroat competition with 25% defect rates, and customers who knew how bad the stuff was and thought it was still a good deal.
