It’s silly how easy it is to repair Xronos Clock if anything goes wrong!  There are no proprietary tabs or permanent adhesives. Almost everything is held neatly by set of machine screws and can be taken apart in less than 30 minutes!
Most electronics are thru the hole, so any of them can be de-soldered and replaced.
Main processor is not soldered and can be removed with IC extractor or just plain flat screwdriver.
All cables can be easily unplugged from the main board
Speaker is probably hardest part to replace, because it’s held with hot glue, but it can be fairly easily detached with simple heat gun or hair dryer!
