I was relieved to open this thread and read "for my watch"... - thought AAM had taken a funny turn!
Jewellers don't seem to stock these as much as they used to, or else don't carry much of a range. Sounds like an ideal [broken link removed] item, if you ask me?
Try Vinny O'Neill aka Goldfinger Jewellers in an upstairs premises on South Anne Street, D2 near Sheridan's Cheese Shop. I've bought leather watch straps (and watch batteries, and jewellery repairs, and our wedding rings! from him in the recent past.
I got a decent leather strap for my watch last week, cost €15 and the jeweller said people often weren't willing to spend that much so i wouldn't worry about having to fork out €30 or more.........
