ryaku Posted April 11, 2010 Report Share Posted April 11, 2010 Hi all, i have a quick question regarding the exact crystal size for a Seamaster 300 2254.80 and Planet ocean 42mm. I just need to know the difference in diameter and thickness. To my knowledge: SMP 2254 Diameter 30.45 mm Thickness 1.5 mm is it correct? PO 42 mm Diameter ? Thickness ? Any clarification would be much appreciated. Quote Link to comment Share on other sites More sharing options...

ubiquitous Posted April 11, 2010 Report Share Posted April 11, 2010 One of these days, I need to pop it out so I can send it in for AR I should also do the gen crown/tube swap as well at some point... Quote Link to comment Share on other sites More sharing options...
ryaku Posted April 11, 2010 Author Report Share Posted April 11, 2010 Yeah, if i remember right it's the only missing mod your franken still waits for. It's well worth it. Quote Link to comment Share on other sites More sharing options...
HauteHippie Posted April 11, 2010 Report Share Posted April 11, 2010 If anyone has these crystals in my current run, I could tell you the dimensions as I have all crystal measurements recorded. I just don't typically know what watches they've come from. The 42 PO is >2mm I think. The 45 UPO is 3.3mm thick. Quote Link to comment Share on other sites More sharing options...
ryaku Posted April 11, 2010 Author Report Share Posted April 11, 2010 3.3 mm , holy [censored]!! SMP should have a 1.5 - 2 mm crystal thanks Chief Quote Link to comment Share on other sites More sharing options...
bosk Posted April 12, 2010 Report Share Posted April 12, 2010 3.3 mm , holy [censored]!! SMP should have a 1.5 - 2 mm crystal thanks Chief SMP crystals vary alot depending on the maker. I've seen SMP crystals that are interchangeable with the 42mm POs. Quote Link to comment Share on other sites More sharing options...
gavidoc Posted April 23, 2010 Report Share Posted April 23, 2010 Hi all, i have a quick question regarding the exact crystal size for a Seamaster 300 2254.80 and Planet ocean 42mm. I just need to know the difference in diameter and thickness. To my knowledge: SMP 2254 Diameter 30.45 mm Thickness 1.5 mm is it correct? PO 42 mm Diameter ? Thickness ? Any clarification would be much appreciated. I own a gen 2254.50 and a gen 42mm crystal. What I can tell you is that they are the same diameter. The PO crystal is thicker but I don't know by how much yet. I am having it installed on my 2254.50 as I modded it with a Gen PO bezel. What I can tell you is that a Gen PO bezel sits about .5mm higher then a Gen 2254.50 crystal but is flush with a PO crystal. To get that extra 300m of depth I'm betting that the crystal is thicker. I'll measure the PO crystal tonight to give you a thickness and after the swap can give you a SMP crystal thickness if you want it.. Quote Link to comment Share on other sites More sharing options...
