Signetics NE5516 (1983)
If you need a bunch of 555 timers for your project, the NE5516 has you covered with 16 individual 555 in a single package. Unfortunately the chip is no longer in production and is getting quite hard to find.

@anthony_berndt @CASIOJapan At the moment it's just a guess as die is much more complicated than needed for "simple" digital watch. We will see more after comparison to old version.

Yes, quartz crystal will have slightly different frequency at different temperatures: https://onlinedocs.microchip.com/pr/GUID-7084EBB9-C955-4749-8739-6C52B858DEEB-en-US-3/index.html?GUID-99D73706-A33D-4F55-80C9-BBEA97A1FA4D

@jms_embedded I am not sure it would qualify for an article... For old nodes I measure width of smallest trace. Around 180nm I measure area of SRAM cell and compare to published data on SRAM density... All this is very approximate, as this "Xnm technology" thing is not very well defined.

This looks like war. At certain point there will be retaliation from China. I afraid many leaders see restraint as weakness. World does not end if you cut stuff <90nm. But China do have capacity to end convenient tech world as we know it.
