Swiss made TESA micrometers are undisputably among the finest available. They have a friction sleeve which lies a bit better in the hand, making one handed operation easier for some. They also have slanted lines on the barrel and that may be a deciding factor when investing in these. Some people can't tolerate those slants. Others have found out that they're easier on the eyes. If you're not sure on this point, select another micrometer such as [Etalon Series 260], made by the same manufacturer.
Metric models are available up to 300 mm. They are almost never in stock in the US. If you place an order online, delivery has to be assumed to be 4-6 weeks.
Inch reading models were discontinued in 2016. Repairs may still be possible. Refer to page 30 for details.

Manufacturer suggestions (paraphrased): Check your Tesa micrometer periodically to see that the zero lines up. Use a gage block to verify readings.
After heavy or prolonged use, it is recommended that the micrometer be cleaned as follows: unscrew the quick-drive end cap, as well as the thimble. Clean each part with an appropriate liquid (alcohol, naphtha) and reassemble. Lightly lubricate the spindle with a high quality oil. Eliminate any play in the thread by using the supplied setting key.
A more detailed maintenance brochure comes with the micrometers.
