i would imagine they’re probably pretty similar in the teardown procedure.
youd have to take care when heating up the screen so you dont get glass shards in your fingers and take it slow when you lift the screen up so you dont tear any cables. as for the screen you might have problems finding replacement screens out there that are reliable since the watch just came out.
i search around on Ali express and ebay and google searching places. from the looks of it i couldn’t find and SE replacement screens :(
