[iMore Question]

Do all apple watches show the series number at the back? Buying one from depop and can’t see the series number, is it fake?

My Series 3 does. Here's a photo...

Without seeing the watch in question, I can only make a guess that it has worn off, or if it only says Apple Watch that it is a first generation, before Apple introduced the Series’.

From the watch, go to settings / general / about. You will be able to determine from there what model it is.

I found this link:

From the link:

The engraving on the back of the watch will tell you. The original Apple Watch just has ‘Watch’ engraved and is sometimes called “Series 0” since it is one generation earlier than “Series 1”. All subsequent watch models have ‘Watch • Series x’ where x is the series of the watch.
