Firstly, its an Asian 2836 copy, not ETA.
Secondly, if you own an UPO, you will immediately recognize the inferior quality of the Silix model when it arrives. Most notably the cheap, sloppy, 90 click bezel.

The date font is wrong, and the date wheel is glossy, not matte as it should be.
Other than that its pretty accurate
