The watch hardware is waterproof (but not submergeable), it works for 1 day without special optimizations (all-disabled-low-power-mode on original firmware about 2 months), it has a sunlight-readable display which should work with GPS for at least 6 hours without any optimizations. That's enough for a trip. It only has 8MiB storage space, but that should cover a couple hours worth of GPS track. It's the same device as used by Bangle.js 2. The web site was put up before I started the firmware work, so obviously no pictures :) They will come once the project becomes more useful.
