Sternkreuz DIA-C and DIA-CF Diaplan Crystals


Recommended Posts

Hi, Does anyone have any experience of using the flat crystals from Sternkreuz? I need to replace a crystal that is 32 diameter and 3.4mm total height. Not sure if DIA-C or DIA- CF(low profile) would be best suited. Does anyone know how the dimensions can be found? Thanks, Steve.

Well, Cousins in the UK were no help as usual. I had to go back to Sternkreuz after they first passed me onto Cousins.

 

DIA – C 320

Outer ø = 320 ±0.02

Inside ø = 305

External height = 3.6

Inside height = 2.1

Ring = 305 * 0.9

 

DIA-CF 320

Outside ø = 320 ± 0.02

Inside ø = 310

External height = 2.1

Internal height = 0.9

Ring = 310 * 0.9

I enquired again regarding the tension ring and was informed that 0.9mm is the height and the ring thickness is 0.75mm.

    • 🤔 leaving the EU meant that UK was no longer part of the convention and have already been turned down an independent reapplication. I'm pretty sure courts have to be held in Switzerland in this case. There will be a lot more watches stashed away in draws  tbh, folk wont be able to afford to maintain them. Cheap watches will be bought and top end watches by folk with plenty of cash that can pay for service and repair. The expensive once in a lifetime gifts and everything else inbetween will be at the forgotton when they stop working. I know i was being a numpty, get used to it 😄 Anybody that knows will boycott them, but besides repairers who will know. Nope will never buy one, i made that decision as soon as i learnt about this. 
    • although not in this case.  It was the Lugano Convention and its deficiencies that allowed a Swiss court decision in the first place.  This isnt really a Brexit issue at all.  A decision that affects both the EU and the UK should never have been heard in Switzerland. I bet the authorised service centres in the UK are pretty pleased.  It's a massive shame, though; I believe watch owners should be able to choose to have their watch serviced by whoever they trust.
    • Hi guys I think that old hippy is correct, it opens the gates for china to manufacture aftermarket spare parts. considering that they already do work on behalf of the Swiss I guess this decision gives the a little more legitimacy to tool up and I am sure they will take advantage of the situation either with or without the blessing of the Swiss watch industry  Having read about the protectionist machinations of the Swiss in the history of Europe they were the only ones to get fat at everybody else’s expense. I think the outcome could have been guessed at but ,  fair play to Cousins UK for standing up to them.  Now the question,  will everybody boycott Swiss watches and Swatch, no way they will still fill their coffers.  Me I stick with the Japanese once renowned for cheap shitty watches who came good through industrial effort and don’t for get the Russians that most dismiss as low grade crap. Wouldn’t buy a swatch product ever how about you all.? a
    • Hold the crown when in winding position, move the click away from the crown wheel, and then while holding the crown let it slowly unwind. I recollect that you must remove the automatic device bridge first, but maybe I'm wrong. You can first try without removing the automatic device bridge.
