I've also heard it called the "top side" and the dial side the "bottom side", which should make any non-repairer very confused. There are many examples and sometimes it comes down to personal preference. Personally, I like to say "dial train" whereas most other people would use the term "motion works". -
Is magnetism such a major problem that we (as home hobbyists) need to spend $$$ on a fancy demagnetiser? I use one of the cheap blue Chinese demagnetisers (£10 from ebay). It works, and has never failed to demagnetise a movement, or my screwdrivers. Magnetometer - who needs one? Take a very small screw. If it sticks to the clean part, it is magnetised 🤣 -

My overall preference is to use traditional names and terms, that became my habit when i was taught joinery by old boy chippies 2 generations older than me , that had their time in the 40's. But what i often do is adjust the names and terms i use according to who I'm talking with. Sometimes i will say trainside and occasionally watchmaker's side. I try to find a balance between accommodating other folk ( there's no point speaking a foreign language to someone who doesn't understand it ) and using a name that appears to me to be more relevant as to its use or description. But using the name lever can be quite confusing, some watches might have parts that are also levers, release levers, which in effect is what the pallet fork is, an escapement release lever. -
Then put the case number in here https://www.cousinsuk.com/category/filter/search-seiko-case-parts and it should give you the crown

I come across to replace the crystal of a 7734 chronograph. What make it special there a printed chapter ring which fits inside the recess of crystal before inserting into the case. I am thinking of a high dome crystal such as Sternkreuz ATCH, fitting diameter OD332/ID320. For this purpose, tension ring will be removed and fit in the chapter ring. I understand the crystal size may not perfectly fit these two dimension. Should aim to find the right ID, then OD can be grinded to reduce without much difficulty. To find the right crystal, the easiest way is to get know of the OD/ID relationship of Sternkreuz ATCH/ATCG (otherwise the OD of the crystal and tension ring). I hope you are able to help to minimize the trial and errors.
