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.

    • Oh well, if Master @nickelsilver says it's the way to go, then it is the way to go! I stand corrected! 🫡 Are there any other places where you're supposed to remove the epilame from the contact point of rubbing? I don't think so! Thanks for the effort @Neverenoughwatches, much appreciated! 🙂👍
    • If you're seeking advice for your "Harvard GSD" MArch II application essays, I'd recommend taking a thoughtful approach. Reflect deeply on your experiences, passions, and goals, and tailor your essays to showcase your unique perspective and potential contributions to the program. As for resources, I recently stumbled upon a gret platform for essays, and I must say, it's been quite helpful. Their selection of pre-written essays covers a wide range of topics, and their professional writers can also assist with custom essays tailored to your specific needs. Check out their offerings here: https://essaypro.com/essays-for-sale. Remember, authenticity is key in your application essays. Good luck!
    • For clarity and ease of testing, I redid that diagram, flipping the circuit to match the layout of the physical watch.
    • Hello, Thanks for the reply. The old jewel will get pushed out from the "outside" which is the dial side. The new jewel will get pressed in from the inside (shown below) which is the movement side, correct?     And the old jewel and spring will get pushed from the is the "outside" which is the dial side. Thank you very much for the information. I will take out the KIF spring and save it. Will update when the new jewel is in place!   Regards, Joe
    • It's a little circlip style retaining clip to keep the pinion from riding up out of position.
