Spring bars with 1.1mm tips that are 1.8mm thick in the center, allowing fat tip spring bars to be installed in standard straps. Includes 2 spring bars. While all of our straps fit safely and securely on Seiko and Citizen watches with fat lug holes such as Prospex and Promaster, some customers don't prefer the slight wiggle that is present when installing them on Seiko and Citizen divers. The quick-release spring bars standard in our straps feature 0.8mm tips, while Seiko and Citizen diver spring bars use 1.1mm tips.
Seiko and Citizen fat spring bars also often can't be installed in standard straps, as they are too thick to fit.
This is why we've developed a new spring bar! It has 1.1mm tips but is 1.8mm at the center. This allows it to be installed in StrapHabit straps and Stainless Steel bracelets, as well as any of your other favorite straps.
