Where to purchase curved spring bars

Hi all,

There's not much a lot of info out on the web, but I am looking for 2 pairs of curved spring bars for my JLC RDM 21mm lug width.

I emailed a couple of dealers in AU and i've been told they don't supply spare parts, but only watches and accessories.

I am unsure if the ones from Ofrei will work, but if it does, what would be the correct ones?

Regards,
