I bought a bunch of Made In USA pencil depth gauges 30 years ago, pre-Interwebs. I eventually wore all but one out, which is still in the wrapper. After a few years, the plunger doesn't stay put in the cylinder. The ones they sell now are identical,,but Made in China.True, and there's a very good reason for that, which doesn't carry over to the gauge: The Seiko is purely digital with no moving parts.
I trust cheap electronics to have reasonably consistent precision over time. That trust doesn't extend to cheap mechanicals. I'd bet that my decade-old pencil-type depth gauges have developed at least 0.1mm (not 0.01mm) of slop by now. That digital widget is fundamentally the same design with the addition of electronic measurement of the pin's position. The cost and quality of that basic mechanism is probably similar between the two; I'd expect their reliability over time (or lack thereof) to be similar as well.
But as you noted, the trend's the thing, and the trends you're looking for are well above the 0.01mm noise anyway.
