So far so good! Used them on two NATO watch bands and they are holding up great.For some reason, Casio makes it tougher to find band pin sizes than nuclear codes. . .variety pack has you covered, with a great installation tool as well.These are just standard size spring bars. The quality is average and mediocre. They worked just fine for me but I expected better quality. I would not get these again nor would I recommend them.I ordered these because I was unable to get replacement bands that fit my Garmin Venu 2. This fixed the issue, and while it annoys me that I can't use the pins that came with the bands I ordered, this at least allowed me to use a velcro strap that I prefer over the band that comes with the Venu 2.They work perfect, thats why i gave it a 4They arent as durable as one would hope, if your strap isnt full width, i thought they would look a bit more rigid, thats why i gave it a 4. the bent one i replaced, was the exact same looking pin. however, this time i have the right band in there...I just finished installing one of these bars as a replacement for one that I broke by accidentally dropping my watch on my bed. The watch I installed it in is an Invicta Pro Diver Chronograph (photo included for scale) which for anyone not familiar with the brand/model is a fairly heavy watch.The bars support the watch well and have a nice amount of tension on the springs. They also don't appear to be any larger than the previous bars I had installed, but definitely seem to be more sturdy.They were packaged well (photo included of the package minus the bar I had already installed) and arrived earlier than originally projected.Their customer service also seems to be top notch as they went out of the way to send an email to ensure everything went well during the buying/shipping process.I would highly recommend this product and seller to anyone looking for good quality spring bars. I definitely plan on ordering these again in the future as I will likely need more spring bars for this and other watches in my collection.Watch shops did not carry 38mm so resorted to looking on line and found these - perfect fit. So after 5+ years I can finally wear my favorite (and most expensive) watch again!I purchased the 26mm, 1.8mm spring pins. It fit perfectly into my Invicta strap. The OEM spring broke as I removed it from the watch because Invicta often makes it difficult to remove. Too much force, and I was left with a 26mm spring from a watch repair kit. It was far too flimsy and once detached when I picked up the watch from the table.These pins are perfect for invicta watches. The flanges make them easy to insert and easy to remove. And if you compare them to a spring from a repari kit, these DURA SPRING pins are far superior. They are well-machined pieces.Right size. Expected to be a little more heavy,but works well,time will tellMontre
