Description
Seiko Compatible Premium Spring Bars
Reinforced spring bars, also called pins , designed for Seiko watch straps and professional diving watches. Available in 2.0 mm or 2.5 mm diameter, they provide ultra-stable fixation, reduce strap play and offer optimal comfort on the wrist.
We manufacture these spring bars to a higher standard than the original Seiko parts ( ref. C220FS ), using Premium 316L stainless steel , the same alloy used in high-end watch cases. Our customers have noted a higher quality and a firmer spring than the original models, providing better bracelet retention, even in extreme conditions (diving, sports, humidity).
