Sorry, I missed that you had already mentioned the date above, but it helps to see your departure time.
There is no EuroCity departure from Spiez at 7:30. Are you perhaps connecting to it from the 7:29 train from Interlaken Ost to Spiez?
If so, the EuroCity leaves Spiez at 8:05, and occupancy in both 1st and 2nd class is predicted to be low, so you should be fine without a reservation.
It would be good if you could let us know how it worked out after you get to Domodossola :-)
