Could anyone confirm that a Speedy 1450 bracelet would need 20mm long spring bars with 1.8mm diameter? http://www.ebay.co.uk/itm/4-8-12-X-...hash=item35faf5a58d:m:m-5iUMrMd1Kn1G7fEmEJHqAPurchases made through these links may earn this site a commission from the eBay Partner Network Would these do the trick? Much appreciated
