hmm.. That looks very similar to the cases on the Parnis B&R homages...
I think a good and cheap start would be to ask Jackson Tse as he has sourced me spare bars for my Parnis homages for $2 a bar with screws.
If you ask him if he can get some spare strap bars for the HW41 he stocks (his english is good but not that good, so keep it fairly simple! lol) he might be able to sort you out
Scroll down on here to find the HW41 reference he uses:

(hope it's ok to post the link, mods - I'm not sure if he's a trusted dealer on here but he is on RWG1.1, so please remove it if necessary )
And if they don't fit then, hey, what's a few dollars spent on testing? Cheaper than a whole new watch straight away, especially if they do fit and the problem is solved
(Oh, he doesn't sell the strap bar tool though - if you've not got one you might have to ask Topwatches2009 on ebay as they've supplied me before, but robbed me for $10 for each tool + $5 posting... )
