Yes, 30 days for manufacturer defects.

Eric self-funded Core Devices and likely doesn't want to take on what would effectively be personal liability. So I presume it will always be 30 days unless they get more leverage with their manufacturing contract (e.g. larger volumes)

Edit: Or I suppose if they earn back the initial investment and become fully sustainable, then maybe they'd be able to extend warranty and eat that cost themselves

That doesn't bother me at all given how inaccurate most smartwatches are for measuring heart rate. What does bother me is this uses glue while the Time 2 uses screws. It makes this much less repairable. Plus many apps and watch faces have better support for rectangular screens. I love the design enough that I switched my order, but I may still end up switching it back to the Time 2.
