We assumed it might have been a local squaddy's watch ( you know, all that LOA they get ? ) but nobody wanted to claim it.
Follow on crew got no better luck in tracing an owner.
Later we tried a Google on 216 Sqn and got a website that looked promising . . but that's all it was . . promising but nothing else. Turned out to be dated and defunct ( the website that is )
Then someone suggested old Pruney. Worth a shot we thought.
If no joy then we can always try e-bay I guess !
Happy Flying
