Call from AD ? Mistake ?

[Lever Escapement]

Had a strange call from my AD this afternoon.
I didn't recognise the number that came up on my phone as I didn't have the AD's number saved.I was busy with work and thought it was a colleague that I was expecting a call from.
When I answered and said my name there was a long pause and they seemed a bit perplexed. There was a little bit of stuttering and it was almost as though they had phoned the wrong number. They anounced who they were and stated "We were just checking up on the model that you had requested". When I confirmed the model (No Date Submariner), they said "No problems. Have a nice day and take care".
It has been almost a year since my expression of interest.
Will I be getting another call soon or did they make a mistake and I'm getting my hopes up for no reason ?
Thanks.
