Finding a good replacement bracelet for your vintage 6139 is not easy. Many of the aftermarket offerings are made of light, cheap metal, and are hugely disappointing. This is a heavy-duty, solid-link bracelet you will be thrilled to wear. I find these to be better than the original Seiko bracelets, and in fact, I have used them to replace all of my originals! You won't be disappointed.
The listing includes the H-link bracelet and a pair of end-pieces to fit the 6139-600x chronograph. The end-links are a folded metal, but much stronger than the original Seiko end-links. Fits up to a very large wrist, with many removable links and micro-adjustments on the buckle. As always, it comes with a pair of spring bars.
