it's a un300 bb that's 68x107, they're 2013/ 2014 specialized langster oem cranks (which i do not believe to be rebranded suguino era) so a JIS BB - all information about the cranks lead me to believe it should be JIS as they're not euro cranks or particularly old
there is 0 markings on the cranks other than their legnth and this weird raised compass? which is impossible to make out
i left the old bb in the frame before giving it to a friend - so i do not know what was in there before and specialized just links 68mm sealed catridge square taper - no legnth indicated

Don’t want to open a can of worms, but is it ISO or JIS?
