Perfect Fit and Secure Solution for My Casio Duro
These spring bars were exactly what I needed to make my Casio Duro work seamlessly with a Seiko Jubilee metal band. The 2.0mm size provided a snug, secure fit with no more annoying spacing or wobble at the lugs. Installation was straightforward, and they locked in firmly without bending or slipping. The bars feel strong and durable, built to handle the daily wear that comes with a dive-style watch. It’s a small, inexpensive upgrade that makes a big difference in both appearance and confidence when wearing the watch. For anyone pairing aftermarket straps or bracelets, these fat spring bars are an essential accessory—reliable, sturdy, and worth every penny.

It’s supposed to be tight
I used these on a “Rolex” style rubber strap for my Bulova diver. Perfect fit! Pro tip: if the bars are tight going into the rubber strap holes, use a tiny bit of soap on the bars, and they will slip right in.
