1.8mm Curved Spring Bars

These fit the bill. I purchased a Bonetto Cinturini Italian Rubber watch band. The bands holes for spring bars were a touch sloppy and looked like they could handle the 2.5 mm spring bars. It was a tight fit, but worked really well!

Beautiful, nice strong fat spring bars . I'll never loose a watch now. Thanks

Heavy duty. Great for Seiko dive watch

Fast Shipment, took all the play out of my leather strap on my Seiko. Thanks!

Fantastic item. Perfect for padded straps.
