FxrAndy Posted December 10, 2009 Report Share Posted December 10, 2009 Excelent info. I run the mangnetic test on serveral watches i have at my work. Breitling BCE v1: Bracelet: magnet wouldnt stick. case: magnet sticks although not very solid a bit of a shake and the magnet drops. WM9 yachtmaster: case and bracelet same as the BCE case, sticks though ever so slightly DSN PAM 27b: Same as with the WM9 and BCE case. The buckle however would not know nothing from the magnet. Looking forward to the next episode of mythbusters. This is very interesting! Now we're talking, I love threads like this! I have a very strong magnet here with me at my desk at work, and I'm wearing my Skyland V3. Bracelet (links) No magnetic attraction at all. Bracelet Buckle- light attraction, barely sticks. Watch case- no magnetic attraction at all watch case back- STRONG magnetic attraction. IWC INGY light attraction to the bracelet, stronger attraction to the case back Quote Link to comment Share on other sites More sharing options...
Bike Mike Posted December 11, 2009 Author Report Share Posted December 11, 2009 Now correct me if I am wrong here, but just touching a caseback with a magnet to test attraction, I would imagine, is no good for a watch. However, since some casebacks are exhibiting magnetic properties, I would think that these watches would exhibit all kinds of weird problems even without being near a magnet. Think of it, your caseback is a magnet, and right up close to the movement 24/7, with no Faraday cage or shielding. Your case back is not Quote Link to comment Share on other sites More sharing options...

Katerchen Posted December 11, 2009 Report Share Posted December 11, 2009 Then it dawned on me that my chrono avenger is made of titanium. I'm just a f__king idiot sometimes Excellent Info!! ------------------------------------- @andreww concerning titanium and magnetism i found this on the net: "...Titanium is Paramagnetic. This is a form of magnetism which occurs only in the presence of an externally applied magnetic field. Paramagnetic materials are attracted to magnetic fields, hence have a relative magnetic permeability greater than one (or, equivalently, a positive magnetic susceptibility). However, unlike ferromagnetic which are also attracted to magnetic fields, paramagnets do not retain any magnetization in the absence of an externally applied magnetic field."

upland Posted December 12, 2009 Report Share Posted December 12, 2009 The iron-carbon diagram on the way..? Great info,thanks Sir! Quote Link to comment Share on other sites More sharing options...
FxrAndy Posted December 12, 2009 Report Share Posted December 12, 2009 Good point about the bracelet pins Mike. Still on the same point, someone was asking the while ago as to whether the farady cages in out watches like the milgause and ingy actually works. Well they don't because i was able to stop all my reps with a STRONG magent but not my gen, so "just for looks" gents on that point. Quote Link to comment Share on other sites More sharing options...

Bike Mike Posted December 12, 2009 Author Report Share Posted December 12, 2009 The iron-carbon diagram on the way..? Great info,thanks Sir! Not a problem I have nightmares over this diagram. Had to memorize it and sketch it, label it, and discuss each transformation phase in detail for my metallurgy final! Then sketch the micro-structure for each phase transition! So who wants a lesson in eutectoid temperature and Austenite-Ferrite transformation? Thanks everyone. I will try to get a update posted tonight. My work serves seem to be having issues, so I am not able to pull down the micro-structure images of the bracelet. Might only be able to do a minor update.

mad dawg Posted December 15, 2009 Report Share Posted December 15, 2009 Fantastic article! In my profession, certification of materials is a big deal. Thus I was alway REALLY wondering what the PMI/Spark test would yield for so called 316 watches. Well done!! Quote Link to comment Share on other sites More sharing options...
