Rolex case part numbers for pendant tube and crown ?

[CYCLOPS]

you could maybe find a suitable spring bar spring to work in the crown, a lot of times both the crown and tube are worn and will not function, especially when you put the flat gasket in the crown, if you have some tapered reamers you can use those to remove the damaged tube, after-market tubes are everywhere, use the 5.3 crown and tube,  there are different 5.3 tubes, you should get the style that uses the tube wrench, there are endless tube tools on eBay for you to look at for reference......there are also taps to fit the case

It seems that the springs breaking is a common occurrence in these crowns. If you don't realise you can disassemble and change the spring, you can waste a lot of money on a new crown.

I measured the spring as : Outer dia 1.35mm, Inner dia 0.85mm, length 3.5mm, wire thickness 0.25mm.

I managed to find a close match on https://www.leespring.co.uk/compression-springs

Outer dia 1.4mm, wire diameter 0.25mm, length 3.5mm

Just remember about my post from above showing the 7935 as 24.5300

Parts just arrived

The 24.5300 fits perfectly. I need to ream out where the splines are for the stem to fit. It does mention this in ads for generic parts.

The springs I ordered for the stem fit perfectly too , as do the case back gaskets.

Cousins list the Rolex acrylic as restricted, but I found a good match in the Sternkreuz catalogue - XS178.198 which fits nicely

Thanks for your help

Thanks for the update.

I think that answers the question that it should have been the 24.5330 with top splines.
