According to https://developer.apple.com/videos/play/wwdc2018/239/, WebKit on watchOS 5 will override meta-name="viewport" content="width=X, initial-scale=Y" declarations, and present with a 320px-wide viewport (initial-scale=0.49) unless you say some new, magic words:
<meta name="disable-adaptations" content="watch">
With that, the watch presents using its actual, native, 156px-wide viewport.

According to the spec, new
name
values should be registered on the WHATWG wiki.And
disable-adaptations
should be specified...somewhere. Maybe in CSS Device Adaptation?
