    What kind of spring bars are these?

    They measure 1.77 mm in diameter across the tubes, the ends are 1.18 mm. Second question if the first is answered, do they come in 1.50 diameter? Thanks!

    Otto Frei (Otto Frei Call 1-510-832-0355 For Watch Parts) has numerous spring bars, including different widths.

    Yes, you should be able to get them in 1.5mm Frei.com or esslinger.com

    Thanks for the replies. Does anybody have a direct link? I'm not sure what I'm looking for.

    Those look like thin springbars with fat tips for using aftermarket straps on seiko divers that come with the fat bars. I have not been able to find them at Otto Frei or esslinger. I get them from eBay seller twente(o) who lists them as 1.78mm with 1.1mm tips. I have not been able to find 1.5mm ones, although it seems that would be a better fit for some rubber straps. Some other sellers list dimensions as 2mm with 1.2mm ends.

    Thanks taike, that's exactly what they are. I bought an aftermarket clasp to replace the cheap stamped steel clasp on one of my watches. I was unaware at the time the pins would not work in the bracelet. Even if I could find 1.5 mm bars, I think I'd be hesitant to use them, I'd think the tube would be much too narrow/thin in relation to the tips. I guess my only option would be to have the 1.5 mm hole in the bracelet end links drilled out to 1.8, though I'm not sure where I'd get that done.

    I guess my next question would be where would I take this to get the hole for the spring bar enlarged from 1.5 mm to 1.8 mm?

    probably a machine shop that specializes in micro machining, like for aerospace.
