nnomad Posted March 20, 2009 Report Share Posted March 20, 2009 (edited) Hello Guys, Once again, its been a pleasure to read almost all your posts for the last month..its been a trully amazing experience, and my understanding of watches, has stepped up to a level where im no longer a plain idiot..just ignorant in a less insulting level.. Thanks to you guys, I just made my first "decent" and serious purchase, a beautifull UPO from PT (by the way..great communcation and fast as bullet giving answers to my rather stupid questions..A++ seller! ) White numerals, rubber strap .. oh..he's a beauty indeed......and, to be honest, its been 2 days since i ordered it and the waiting is already killing me, go figure...( and the ironical part is..i actually never cared all that much about watches..until now). Is there anyone right now available in EU for the double AR treatment?... I've read that some watches have somekind of restrictions when setting the date (which if done incorrectly can damage the movement) .. how does the UPO works regarding that subject? One last question that i wasnt able to find the answer for.. Is there any replicas being made with the 314L steel?.. or the only one used is the more common and less expensive 316L? .. is there any obvious difference between both? (visually speaking) Ill post pics of my new UPO once it arrives.. again, thank you all so much for great support! cheers guys A.

Guest Sql_pl Posted March 20, 2009 Report Share Posted March 20, 2009 There was one great european based AR master k2222 but something went wrong and he dissapeared. I do not know if there is anyone doing it in Europe now. Date change restrictions apply to 7750 movements only. You should not change date between 8 pm - 4 am because date change gears are engaged and you can damage it. No worries about your UPO, unless it's chrono PO. As for steel - I think By-Tor had a take on this subject when he was comparing his gen Rolex and a rep. These differences are barely noticeable so no worries. Have fun with your UPO!

coolfire Posted March 20, 2009 Report Share Posted March 20, 2009 I can only answer on the steel question dude. there is no 314L, only 304. though the dealers always claim our watches are made from 316L. gen Rollies are made from 904 steel.

castlemountain Posted March 21, 2009 Report Share Posted March 21, 2009 I can only answer on the steel question dude. there is no 314L, only 304. though the dealers always claim our watches are made from 316L. gen Rollies are made from 904 steel. I am a mechanical engineer, also a noob, sticking my head out.. 304L is a lower grade to 316L, 316L will actually stand for acid, at least some of them and for some time. 904L I think is equivalent to 316L, it has some other components and might be better in some areas. I do not think it is a big difference. I would think the Rolex engineers says 904L is best for Rolex and watches. And others, perhaps Omega engineers says that 316L is best for watches. Strenghtwise they will be the same, also 304L. It will not be worse to have a watch of 304L. Normally we do not get our watches in contact with water, so not a big chance of get in contact with acid. I am in no way a metallurgy specialist, so others might know more about this, just a common mechanical engineer 304 & 316 can be both 304, 304L, 316 and 316L - not a big difference there either. I guess it is the same with 904L. Also all these steels are what we all call stainless steel, which is quite a big category. Quote Link to comment Share on other sites More sharing options...
