Mitutoyo has always been Asian, personally I have never been impressed with any of their tools especially their dial calipers (I have an 8" Mitutoyo dial caliper it was cheap I needed one). I must admit I kind of walked into Mitutoyo with a bad attitude, first shop I worked in it is a pretty good size job shop, I packed all of my tools in to the building, most of them were pawn shop tools or estate sale tools. The guy that hired me asked me if I had any Mitutoyos in my tool box, I said I had a few and his response was "Take them home we don't make scrap parts here" He was a little old man ( well old to me at the time) In a blue shop coat that kept all of his tools in a Gerstner and had been machining since the Korean war.
I have had to use Mitutoyos for years depending on the company, most of the ISO 9001/ AS9100 certified companies provided their own tools because they could keep track of them and maintain constant calibration to meet ISO standards. The large companies would buy Mitutoyos because they were cheaper then the Brown & Sharpe/ Starrett counterparts and they were on the traceable manufacturers list so from a bean counters perspective it is a better choice when you are buying 100+ micrometers at a time to buy the ones that are 5% cheaper. Also and somewhat ironically in my dealings several of those companies I have had the pleasure to work for have banned digital gauges for the simple fact it is to easy to accidently rezero the readout and make bad parts. When your average part is $1000+ USD and you find you scrap out 20+ parts a month because someone re-zeroed the micrometer .005 off of zero and they ran 10 parts before they checked it again, yes even old machinists made this mistake.
That being said, I do have new Starrett micrometers in my classroom, and I have old Starrett micrometers in my toolbox, I like my old micrometers a lot better, not because the quality, because the quality is just as good between the two, I like the older design better then the new ones, I know why they changed designs because it is cheaper/easier to produce. That being said, the same quality is there, between the two, they still have the same weight and feel just as rigid. I have a set of Mitutoyos and a set of Fowlers in my classroom and the Fowlers are exactly the same as the HF ones you can run down and buy, they even come in the same plastic case, they just have a premium price over the HF ones. The Mitutoyo micrometers still have the same stupid plastic spindle lock that always gets broken off, and the same craptacular ratchet mechanism, they are not brand new, they are about 4 years old, but the new ones you look up in the tool supply are the same as the old ones. I have seen the same problem in Mitutoyos I have for years, its kind of sad when you buy a dial caliper from them and it comes with a dial reset tool in the box because it will loose accuracy.
But I think it is what you are comfortable with, I use Starrett micrometers, Hexagon metrology calipers and finger indicators (hexagon owns Brown & Sharpe, Eatalon, Interapid, Tesa and some others). A lot of it is the feel of it. if you don't like the feel when you pick up the tool you wont like the tool no matter how high quality it is. Look at Brown & Sharpe micrometers, they are great micrometers, maintain good accuracy and are well built, but I hate the feel of them so I wont buy them.
