GenTLe 1,493 Posted February 24, 2017 I have a couple of Noob subC, a hulk v3 and a black V5 (and also a BP PRoHunter GMT 2). Measuring the diameter of the crystal, without taking it out, I read around 30.4mm, so I suppose it is a 30.5mm as normal for a Noob one. May someone help me to get which is the right one 2.3mm tall to select? At cousins, if I check in the "Rolex non branded" parts, I can select up to 29.6mm (internal) size: https://www.cousinsuk.com/product/glass-gaskets-iso-swiss-additional-sizes or 29.5mm: https://www.cousinsuk.com/product/glass-gaskets I'm a bit lost... Thanks in advance! GenTLe Share this post Link to post Share on other sites
Rx4Time 1,472 Posted February 25, 2017 The Rolex part number is 25-295-C12 for a subc. The crystal gasket height is 2.3 mm. I unfortunately don't know the diameter. Are you just looking to lower the height of the crystal to match gen? Do you have a crystal press? Share this post Link to post Share on other sites
GenTLe 1,493 Posted February 25, 2017 IT's just to lower the height Share this post Link to post Share on other sites
GenTLe 1,493 Posted February 25, 2017 Thanks to botsyboy (RWI) I got the size: 29.5mm, on CousinsUK it's the R30520 THe fact is that the crystal of rolexes are smaller in the hidden part, so even if outside it is a 30.4mm, then below it's a 29.5. See a Milgauss one for example: Share this post Link to post Share on other sites
