2 Pair OEM Fat Spring Bars 316L Stainless Steel 22mm x 2.5mm x 1.0mm - Seiko Dive Watch

Two pair (4 pieces) of our high quality, 22mm stainless steel, OEM "fat spring bars." These are an absolute requirement for your Seiko Dive Watch. Standard spring bars are a much smaller diameter, anywhere from 1.5mm to 2.0mm. Our OEM fat spring bars are ~2.55mm in diameter.

About 316L 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! Our fat spring bars are identical to the original Seiko fat 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.
