Monday Mystery

Last week's mystery was difficult to identify exactly



Most people could see it was a buckle, but of what?
Dave hedged his bets but did include the right answer



part of a watch strap.
My thanks to all who had a go.

This time I have a full picture of the mystery object but from an unusual angle.



Whatever can it be?

If you would like to make a guess please leave it in the comments.
They will be revealed, along with the answer, next Monday.
