About 316L Stainless Steel OEM Fat Spring Bars
Our fat spring bars are made of 316L stainless steel -- Rolex uses the same 316L stainless steel for their spring bars. That's good enough for us, and our fat spring bars are virtually identical to the original Seiko spring bars.

Note: The ends of the fat spring bars are 1.1mm in diameter. These will NOT fit all watches. You need to make sure the lugs on your watch will accommodate a pin size of 1.1mm.
