OEM Diver's Fat Spring Bars 6 Piece Non-Magnetic Stainless Steel 22mm x 2.5mm x 0.8mm Double Fringe

These perform very well and keep my stainless steel watch band properly aligned with my Seiko diver watch lugs. Being a bit obsessive/compulsive, I like that. Their true beauty is in the double fringe which eases installation and makes removal possible without scoring my watch and greatly reduced frustration.

These are the thicker bars that are used in Seiko Dive series watches. I measured them and confirmed that they are 2.5 mm thick, and the tang (the part that that sits inside the lug holes) are .85 mmMost stock spring bars measure a wimpy 1.8 mm. As a habit, for greater security I usually replace all the stock spring bars with thicker ones on my sport / field style watches.I used these on my Seiko 5 SNZ field watch and they fit great, even with thicker Nato straps

I had purchased 22mm Jubilee band for my SRPD but it came with pins that were too big to fit in my .8mm post holes so I pulled the trigger on this and it fit great!

These are really heavy duty watch band pins. Unfortunately they will not fit my Seiko watch. They are too fat. A real shame since I can't find a pin that will last. The watch is heavy and if one does work such as digging with a shovel, a regular pin will bend and the watch ends up in the hole.

Not original seiko. The pin where it fits into the watch lug is half the thickness of the original. It wobbles and makes a clicking sound as it moves. Dont buy

Bought these for a Casio Dive watch I kept bending pins while Farming. They fit but a very tight squeeze through the band! They lasted all Yesterday, we'll see ;-)

Seller was very professional and I'm really happy with them. Awesome deal for the big fat sturdy spring bars. I'm converting all my watches and will be ordering more

If your watch has the factory fat bars then replace them with these. This design should be the default design for Seiko dive watches.
