  1. Ran across this next store , never saw it posted here. Good stuff! Memeber ALE7575 did this great work, all hail! Posted 07 December 2014 - 07:38 PM KW PAM382 Bronze material – Official Chemical Analysis We all would like to know the chemical composition of PAM 382 reps bronze material. Therefore in order to get the answer I contacted some months ago with KW owner Mehmet and Puretime’s Angus asking them for case samples of KW and ZFac PAM 382 respectively. In parallel I contacted with official Spanish laboratories trying to get a free but reliable chemical analysis of the samples. KW’s Mehmet was immediately willing to send me the sample when the Laboratory was ready. But it was not able to get ZFac sample, because Puretime told me that he had already sent a sample from ZFac to another member (Pete M) in order to make the same official analysis as I wanted. In August 2014 I got, through a friend of mine (an engineer colleague), the possibility of a free chemical analysis from a first class Official Spanish Laboratory. I ask Mehmet for the sample and in some days I received the sample of KW PAM 382 case from Kuvarsit. The sample was an unfinished KW PAM 382 case before machining, taken directly from the current production as I asked to KW. You can see the sample received in below pic. SAMPLE OF KW PAM 382 CASE BEFORE MACHINING At that moment my fried was just starting his summer vacation and I had to wait until the end of September to send him the samples In October my friend got the sample to start the chemical analysis of the bronze. I have the results from about 20 October, but I have not found time to prepare this thread until this moment. TECHNIQUE OF ANALYSIS I wanted to get a chemical analysis by an Atomic Absorption Spectrophotometer, because that was the analysis method I was used to using when I worked in metal alloys. But my friend told me he liked to use a more modern system. It was used one of the most modern, reliable and precise techniques available at this moment: Scanning Electron Microscopy (SEM) See below link for more info: http://serc.carleton...niques/SEM.html http://www.labtestin...g/sem-analysis/ To get an idea about the sophistication of this method, you should know that the cost of the equipment to make this kind of analysis is about 3 million Euros. Of course SEM is a very reliable method of chemical analysis and there is no doubt about the precision of the results. PREPARATION OF THE SAMPLE It was necessary to cut a part of the case to make the analysis. The Laboratory cut a lug of the case to prepare the final sample to be analyzed. This lug was slightly polished to be introduced in the SEM device. You can see in below pics the lug detached and prepared. SAMPLE OF KW PAM 382 CASE WITH THE LUG DETACHED AND PREPARED TO BE INTRODUCED IN THE SEM ELECTRON MICOSCOPE THE RESULTS In the figure below showed you can see the results of the chemical analysis extracted from the SEM Electron Microscope. The square marked in yellow is the chemical composition in Weight%, which is the composition we were looking for. CONCLUSIONS As we can see from above Figure the bronze of the sample KW PAM 382 studied has a chemical composition about as follows: Cu (Copper)- 93% Sn (Tin)- 6% Zn (Zinc)- 1% Therefore, KW bronze is not exactly a CuSn8 like gen, but it is very close to this material. Mainly we can state without doubts that KW bronze is a TRUE BRONZE (it is not at all a Brass, as many people have commented) I have knowledge about this matter because I have worked many years (many time ago) producing Bronzes and Brass and another alloys. KW bronze is actually a CuSn6Zn1 bronze. It is really very similar to CuSn8 and the colour and properties are almost identical to gen bronze. In below Figure you can see the differences between a gen bronze CuSn8 and the CuSn6Zn1 and KW bronze. As you can see differences are a little less content of SN, but a bit more of Zn (less than 1%). Differences between KW bronze and CuSn6Zn1 are almost non existent. Indeed both are the same material. In practice and bearing in mind the application in a watch case, we can say the materials are actually equivalents. In other words: We can expect from KW bronze the same properties and behaviour regarding appearance and patina creation that we will get from Gen bronze PAM 382 Besides, as you can see from the chemical analysis, KW bronze has no impurities. That means that this alloy is made from almost pure metals and using no recycling materials. Therefore KW bronze used in KW PAM 382 is a very good quality alloy. To get a better idea of above statements, you should know that we are using Stainless Steels for super reps much more different from the gen SS than the differences observed between CuSn8 and CuSn6Zn1. To illustrate this matter read my thread about Stainless Steels in watches: SS 316L vs. 316F vs. 904L- The final VERDICT- A technical study http://www.replica-w...ead.php?t=82263 As you can see in above thread the differences between SS 316L and 316F and mainly with SS 904L used by Rolex are way bigger than differences found between CuSn8 and CuSn8Zn1. See below figure where the differences of three SS are showed and compare these differences with the bronzes table differences. Despite above showed differences of composition, we are using SS 316L in some watches made of SS 316F and vice versa. And we are always using either PAM 316L or PAM 316F to make the super reps of Rolex, which the gens are made of a very different SS 904L as you can see in above table. Being the KW sample unfinished and not machined, polished or brushed I was not able to make a reliable comparison between the KW sample and the bronze of my KK PAM 382 V1 from May 2014. But cleaning and brushing a little the surface of the sample, and using my experience in these alloys, I would say that my KW PAM 382 V1 and the sample are made form the same material (it is almost impossible to get a reliable comparison by pics, because some pics seem identical and other different, just a direct visual comparison can show the materials are very close in appearance) Unfortunately we have not the same analysis of ZFac bronze. Some people is saying, and some reviewers and reviews (remember NCcheff reviews http://www.repgeek.com/showthread.php?t=234018 & http://www.replica-watch.info/vb/showthread.php?t=187564 ) that ZFac material is more reddish than KW bronze. From the pics I have seen, I have to agree with these observations. That just means that ZFac material, most likely, has higher content of Copper (Cu) and less Tin (Sn) and other elements, what goes against the quality and properties of the bronze alloy and detaches Zfac bronze from the gen. But that is just a speculation from pics and comments. Anyway, forget the colour on the pics, the false comparisons, the patinas, the speculations… Now we know what we are actually getting when we buy a KW PAM 382: a true bronze CuSn6Zn1 of very high quality, from which we can expect the same colour, properties and behaviour than a gen CuSn8 bronze ************************************************* I would like taking this opportunity to say many thanks to KW’s owner Mehmet for being so kind (and even brave, why not to say it) sending me the sample of the KW case to make the analysis, and congratulations to KW for the good results of this chemical analysis.

  2. My 5517 slapped together ? 702 crown on the way, I just got too excited to get it together. Also working on another custom dial with someone as I'm not quite pleased with this one.

  5. So it's my first time ordering a Rep. After being a longtime lurker on these forms, I have finally decided to pull the trigger. The watch I am looking to get is a noob v4-v7 Hulk sub. I was wondering if anyone knows of any promotions or good deals on a TD's site or profile. Any advice helps! Thank you!!

  7. What meds are you? The bipolar disorder, is it type 1 or 2? Regarding addiction, you have a huge predisposition due to your bipolar diagnosis, and you will be inclined wether you like it or not to alter your state of mind with behaviors and if that is too complicated with chemicals. My tip to you, speaking from experience. Don't try to drink less, ergo don't try to limit your consumption, cut it fully. And it will be hard, relapses are part of it. If you need someone to speak with, send me a PM and I will do my best to aid you from both a professional and personal experience. Admitting the problem and asking for help is the hardest obstacle. Congratulations! Now starts the rest of your life!

  10. Some good piece of advices here. I'd corroborate with [mention=34236]altesporsche[/mention] on LHR prices, and would add Paris if you know the right people for 30% eligible "VAT" discounts on current Rolex and Cartier.

  20. It is and it works fine for 3135. But I'd suggest this one. He's a watchsmith from CA and machines these himself. They're reps of the real Rolex holders and are AMAZING! He's also making me one for eta 28XX and custom mainspring winders. https://www.ebay.com/itm/112283564583

  21. Aha, good to know @TickleShoes Is that red movement holder a Horotec 09-010-25? Been looking for a 3135 movement holder, and can only find this one, it states for a 3035 Rolex movement?

  22. Hey buddy. I feel your pain, I myself have struggled with addiction for 19 years. I wouldn't call it a struggle anymore though, but I'll always be an addict. Let's get to you. I'm going to give you some advice, and then I'm going to contradict that advice , kind of. The forum is great for sharing and for a sense of belonging. That being said don't expect appropriate or good advice about this topic here. Now I'm going to give you a little advice, seek professional help. The guys on this forum are not professionals and if they are this is not a professional setting. Another piece of advice, put alcoholism on the back burner. You suffer from.a mental illness, let that be your focus. Are you taking your medication? Are you managing your lifestyle ? Including sleep, stress, exercise, nutrition? I can tell you aren't because you shouldn't be drinking, period. My advice is focus on your mental health. Seek professional help for the management of your mental illness and to promote your mental well being. You may be an addict but addiction is a symptom of poor mental well being.

  23. I have worked in Behavioral Health for over 20 years. I am in recovery. Some good advice given here. AA is free and highly effective for millions of people. Great place to go and find support. If you are not comfortable with AA, I might suggest that you seek an addiction professional for a screening/assessment and get some feedback from them. I do know alcohol and/or drugs will exacerbate co occurring conditions. So for folks that have other mental health diagnoses, using either can be problematic. See a specialist though as most of the healthcare system is not experienced in dealing with addiction and co occurring disorders. It is a specialty and takes specific education and experience to be effective. Good luck.
