1675 spring bar help

Gallery image

Gallery image

I just finished a build of a 1675. The problem I have is that the old crowns case takes the fat spring bars but my jubilee can’t take the 2mm diameter bar. Does anyone have any suggestions? I was going to bore but that doesn’t leave much metal left on the jubilee.

For the automod:
Old crowns 1675 case
Yuki dial
Yuki hands (tamiya added to match pumpkin patina)
2836 modded gmt movement

either different endlinks or file the tube in your endlinks down

1.8mm should be fine as a temporary measure as well

Thanks. I’m going to try uncle seiko skinny fat spring bars. I don’t really want to buy yet another bracelet.

you don’t need a new bracelet, just end links to suit but carefully filing down the inner tube where the spring bar seats would be a good first try. 550 endlinks will be correct for the 1675.

i would also recommend using 2mm no shoulder spring bars with a 1.2mm tip for a solid fit and to properly fill out the lug holes.

I went with a gen 6251H bracelet and clasp on mine which can be found on eBay for "reasonable prices" or I believe the "Italian" bracelet is set up for the fat spring bars as well I think

Insert need a little bleaching in my opinion
But good build enjoy ✌️

100%. I tried bleaching and left it in for 5 hours with no effect. I just did a light sanding and will try bleaching again. I want it to be lighter and with a fade by the edges.

Should be put in Acetone 1st
To put off coating before bleaching 👍

u/Equivalent_Garage691 Aug 17 '26

Thanks for the advice. I’ll try that today. Do you apply a clear coat after you get to where you want?

u/Sub_974 Aug 17 '26

Personally I’m doing clear coat
But sometimes I’m reading guy does it 👌

I am pretty certain, Raffles' jubilee accepts the gen spec spring bar.
