Two days and one sleep tracking is probably doable, but two tracking sessions probably not. It was all fine on the previous Wear OS version, but not after the update.
If you are choosing between 1+ and Ticwatch, the Ticwatch is still slightly better in terms of Sleep-friendliness

Once we get the Pebbles, we will let you know, how it performs and how long the battery lasts. It should be delivered in July.
