  1. Yes, AR can get scratched, and even damaged by chemicals. And rep "AR" is even pathetic on this side.

    On the other hand, good AR like chieftang's and k2222's are pretty hard. Chieftang's AR (and I suppose also k2222's) meets military specs, i.e. it can be hitten with 20 strokes of pumice-stone without showing any sign of damage.

    This classifies it as more scratch resistant than mineral glass, even if lesser than sapphire.

    Rolex is smarter than that :1:

    An even smarter solution is putting the AR only on the inner surface of the crystal.

    Panerai style. :1: :1:

  2. you can use also a stem adapter to make a 0.9mm stem 1.2mm

    but hey... contact me via PM... i am sure i will know a way brother ;)

    Really thanks, t, but no problem here. I took both 0.90 and 1.20 crowns. :)

    My post was just a suggestion to 7750 owners to check their stem diameter before choosing which crown to order.

    BTW, if you are going to make t48 crowns too I will take them as well. And if you are going to also make them PVD, I will take two of those too.

  3. I ordered all my T-crowns in 1.2 size, so I can use them for HW and auto.

    ???

    The only auto movement where you can use a 1.2 crown is the 7750, and if it is a rep 7750 then you still have to replace the stem as the "original" stem is 0.90.

    All other auto movements in PAM reps (2892-A2, 2893, 2836, DG3809, DG3886, ST2530) have 0.90 stems.

  4. You can get both sizes of stems for 7750 - 1.2 and 0.9. Thing is, most rep makers use 0.9 - probably 0.0002 cent cheaper :)

    Thanks, Z3.

    Actually, the ESA 7750 stem (ref. 51.010.23) is 1.20, but, as you said, the 7750 reps rather seem to often use 0.9 stems.

    What leaves us 7750 rep owners quite unsure on which t crown to order -- unless we open our watches, remove the crown+stem, and measure the stem diameter. :black_eye:

  5. that's all true...but is it worth the 3/4/500$ or like a member is asking in the FS section 1500$ w/o the arrow PR hand ?

    3/4/500$?... 1500$??

    Wow! :blink:

    When I said it's worth, I did not suppose such figures.

    Uhm... Considering that gen 028 go @10-13 k$ on auctions, and that a 2892-A2 028 rep is a 99.9% rep once it is re-PVDed, new cyclops, new DW, and new crown installed (all in all well over 1k$), I think that I might accept to spend up to 300$ more for the sake of bringing it to 99.99%.

    On a 027, that cannot go over 99% accuracy due to the lack of recessed PR scale, and that is less expensive to mod as it is not PVD, even 300$ weigh more on the total cost and are less effective on the final result. So I think in this case I would pass.

    Still, that watch is a beautiful watch. ^_^

  6. Tested the fit of t crowns on DSN 44mm auto cases -- a SS case and a Ti case.

    They fit. The outer diameter of the crown tube (I mean the tube attached to the crown, where the stem gets screwed in) is 1.92 - 1.94mm on the t crown, 2.00mm on the DSN crown.

    Those 6-8 hundredths of mm are not enough to make a misfit. The t crown enters into the case tube and it stays firm enough.

    But the lever of the DSN crown guard just touchs the t crown center, it does not firmly press on it. Evidently, the inner thickness of the t crown is lower than that of the DSN crown.

    The result is a floppy lever in the closed position. On the Ti case it was just slightly floppy, on the SS case it was definitely floppy -- differences due to tolerances, I suppose.

    ----

    Also, verified the diameter of the 7750 stem (t recommended 1.20 crowns for 7750 movements).

    It is 0.90mm, not 1.20.

  7. "yeah this skyland is about 2800"

    Whther the watch is a rep or not you specifically said THIS watch cost 2800.

    I disagree. Rxus did not say "this watch", he said "this skyland". As his watch was not a skyland, it was a rep, he could as well being meaning "this model of watch", "a skyland of this kind".

    Actually, Rxus did not undoubtly affirm that his watch was a gen. The matter is on the meaning of "this", whether it was a specific "this" (this watch) or a generic "this" ("this model"). Noone else than himself can know it, and maybe not even himself.

    I would consider it a lack of precision rather than a blatant lie and would live with it at no or very few conscience problems.

    Making the whole thing bigger than it actually is might make the other part wonder about Rxus' mental health more than about his honesty.

  8. E-F-G series decorated movements (paneraipaneraipanerai) with dagger swan neck are out of production and they are getting rarer (and costly, if you can find one) each day.

    Btw, doc, sausage vs sandwich and G decoration vs H decoration are a lot of difference in PAM models. You fill find different PAM models with very few differences than that.

  9. So I tried and installed the stem. I found that the correct depth for winding the stem into the crown is just 1 to 1 1/2 turns from the inner end of the stem thread.

    Please forgive my poor English understanding. Do you mean that the stem should get almost entirely screwed in?

    Do you know if this crwon will fit a DSN 088

    I doubt it. DSN crown and case tubes are quite peculiar in diameter.

    But my t-crowns already are on their way to me, and I'll try one of them on my DSN 104 -- same case as DSN 088.

    Just, I'll be able to test it only on early September due to incoming holiday time.

  10. P8B, you'd better brake your enthusiasm and start reading, or you may end up with wasting your money.

    The 1st watch you linked in your latest post has exactly the same recessed pin, and needle and non-swan-neck regulator that jitai warned you about. Did you make a search about these issues?

    The 2nd watch... logo models and PVD models have their special issues... better searching about them too.

    I am not suggesting that price is not fair for those watches. It actually is.

    Just, you may lately discover that those were not the watches you actually wanted, if you jump on them with no preparation and without even listening at the hints you asked for.

  11. Great! I love them! :clap:

    Anyway, those are better -- and they write better -- than most physicians in my country. :g:

    Just, the one on suicides is absolutely true. Actually, 90% of suicides don't work -- i.e., 90% of suicides really do not want to put an end to their life. :smartass:
