    Help with vintage spring bar sizes!

    I have an old bulova that I need new spring bars for. The size I need is 9mm bar and 2mm thick. I was looking at some on the bay in little bottles but the sizes on them vary but with formats like 20" / 64. Not sure what these numbers mean. Any help? Thanks!

    Hi Bobby,

    Plenty of springbar charts to look at on the interweb. This might help...



    Regards,

    My Bulova came back today from the watchmaker, cleaning of the dial and a new wristband (18mm/19mm/width for the band). I cannot believe you need a 9mm springbar (length), that must be a mistake. Don't worry about the 2mm thickness, 1,8mm will do fine.

    Do you still have the old bars and if so, can you supply an image?

    Re: Help with vintage spring bar sizes!

    I figure the 2mm is so there is a constant flow from bar to lug. This is why it's 9mm having the curved lugs. I bought some gold plated 9mm for a rolex but they wound up having too big of ribs on the end and wouldn't go inside the lugs. I have one original in right now but would like to find new ones to replace both.

    I now see what you mean, couldn't believe the 9mm. You also need the 2mm to be in line with the rest. It now depends how wide and deep the holes are on the lugs and if single or double sholder (see image above) would be right or even single or double flanged to be in deep enough. I see there is a bar still in there, if thats the original, one could see what is need if you take it out and take a picture of it.

    Be careful with the width! Your lugs have no holes outside to insert a pin. So your bars have to be somewhat smaller than the width of the lugs, otherwise you will never get them out again.

    Those jars are in Inches. So (for example) the first jar there is 18/64" (odd number, that, roughly 7mm).

    Re: Help with vintage spring bar sizes!

    Do you need the total bar length then to be 9mm, or just the fixed bar? I have plenty of these that are 9mm in total length and all sizes upward. Let me know...
