alterego Posted May 2, 2012 Report Share Posted May 2, 2012 Hi dear fellow members: I have a doubt. This came as s result of a comment made to me via PM regarding origin of a Sub that I may be selling. I bought the watch as a MBW a few years back from a reputed fellow in the forum. I never asked myself the authenticity (MBW) of the watch until now. Can someone with experience in this area tell me if the watch is a and MBW version of the classic Rolex Sub. Here are some pics so as to facilitate the identification. Thank you all for your valuable help. Alter Quote Link to comment Share on other sites More sharing options...
rosnik Posted May 2, 2012 Report Share Posted May 2, 2012 IMO : from MBW , Mbw peculiarity is the 'no date' 5512 number in the inner case back engraving, I correct it with 1680 engraving on mine one. Helping wil be to have case lugs picture. Quote Link to comment Share on other sites More sharing options...
Akira Posted May 2, 2012 Report Share Posted May 2, 2012 L342XXX serial? Quote Link to comment Share on other sites More sharing options...
alligoat Posted May 2, 2012 Report Share Posted May 2, 2012 It would be a good idea to check out the SN between the 6 o'clock lugs, although the old MBWs had an L341,xxx SN and the newer ones are more correct- with a 2-3 million # SN. Dial looks MBW like as well as the pearl- the flat white pearl. Does it take gen parts, like a crystal and a bezel insert? But bear in mind, the chinese copied the MBW around 4-5 years ago. MBW red sub (as well as white) dial measures 26.2mm which is smaller than the 26.5mm of a gen 1680 dial. Quote Link to comment Share on other sites More sharing options...

superlative Posted May 3, 2012 Report Share Posted May 3, 2012 CGs look a little too stunted. Quote Link to comment Share on other sites More sharing options...
highoeyazmuhudee Posted May 3, 2012 Report Share Posted May 3, 2012 looks like an MBW to me Quote Link to comment Share on other sites More sharing options...
alterego Posted May 3, 2012 Author Report Share Posted May 3, 2012 The watch dial looks smaller than the gen, so the dial must be 26.2 mm, instead of 26.6mm, which would lead me to conclude that this is an MBW watch. How about the "octo" movement ? is this a variant of the ETA or is it a different type ? Is there a thread in the forum(s) where to read about MBW watches ? Hope you can bear with my curiosity.

alligoat Posted May 3, 2012 Report Share Posted May 3, 2012 Looks to me like you're in pretty decent shape. You can't really date the watch by the SN, but it appears to be one of the early ones. Serifs on the date font are another tell, nice bevel on the lugs and the Octo is a Swiss made watch with an eta movement and if it is a 2846-2, all the better- it says 21 jewels on the rotor so it probably is. I think the entire run of 2836s from the beginning were 25 jewels. Now it's on to trimming the crown guards! Quote Link to comment Share on other sites More sharing options...
Star69 Posted May 3, 2012 Report Share Posted May 3, 2012 not sure guys - CGs look too short for an MBW Quote Link to comment Share on other sites More sharing options...
woof* Posted May 3, 2012 Report Share Posted May 3, 2012 not sure guys - CGs look too short for an MBW If that's true, could it be one of the cartel MBW copies? I know the copies have "Polex" but I don't know about serial numbers. Quote Link to comment Share on other sites More sharing options...
alligoat Posted May 4, 2012 Report Share Posted May 4, 2012 (edited) not sure guys - CGs look too short for an MBW No, it's that the crown is too big. The first thing RBJ69, Joe Butts, did to my red sub was swap in a smaller 'rep' crown. Of course he also trimmed the CG's and did a decent job of it also, I might add. This ain't much of a pic and the cgs are faded out, but at least I've got the RBJ crown. This crown is even smaller than a gen 703 OK, my SN is L341062, Orig Polex Design, 5513 on the 12 o'clock end and the inside of the case back says 5512. Joe was buying these from Watchmaster, but they're MBW all day long- old school! Edited May 4, 2012 by alligoat Quote Link to comment Share on other sites More sharing options...
