automatico Posted February 27, 2016 Report Share Posted February 27, 2016 ...or did anyone else notice the MBK 5512 and 5513 currently pictured for sale have sea dweller bezels? The 5512 I got from Reppin last week has the thicker bezel...3.0mm vs 2.15mm for regular MBK 5512/13/1680 and 2.10mm for Clark/ST. This is for the bezel only, no insert. No foul on this because SD type bezels are very hard to find compared to regular 5512/13/1680. Link to comment Share on other sites More sharing options...

No foul on this because SD type bezels are very hard to find compared to regular 5512/13/1680. I haven't noticed. I'll take a look The one I received has correct bezel. In the original thread from last month he had pics with both bezels shown. I knew something was off Bc of difference In xtal height. Didn't even notice the bezel.

automatico Posted February 29, 2016 Author Report Share Posted February 29, 2016 "well lets see. here are two MBKs i had from 2012" Here is a picture of a 5512 exactly like the one I got, same serial number and all: https://rwg.cc/topic/183042-vintage-rolex-5512-5513-5514-1680-red-or-white The 5512 I got has the thicker bezel...3.0mm vs 2.15mm for regular MBK 5512/13/1680 and 2.10mm for Clark/ST. This is the bezel only, no insert. Looks like the 5512 and 5513 pictured in the link above have thicker SD type bezels and the 5514 pictured below them has the thinner bezel. I wonder if MBK used the same mid case and case back for the 5512/13/1680 along with the 1665? Maybe the 1665 just has the thicker bezel and SD lettered 5512/13/1680 case backs. I have MBK 5512, 5513, and 1680 cases apart and the mid cases are 5.0/5.02mm at 9 o'clock (just the case) and average 6.5mm thick including the case necks. The case backs are 5.45/5.5mm thick overall measured in the center including threads and 4.0mm thick not counting the threads. The cases with the case backs screwed all the way down are 10.75/10.8mm thick including the case necks and 9.0mm/9.05mm not counting the case necks. All the cases are very close to the same, just a few hundredths mm difference one way or the other. The 5512/13/1680 cases are all the same size on the outside and from my experiences r/r a few dozen movements in them, the insides are also all the same. The 5512/5513/1680 all have 25.46/25.5mm dial openings, the 5512/13 have proper 26.0mm od dials and the 1680 has what probably started out as a 26.5mm dial cut down (roughly by hand it looks like) to 26.0mm plus or minus. Anyone who has an MBK SD can compare these sizes to see if maybe the main cases and backs are the same. The SD mid case may he a hair thicker, I can not tell from the pictures. I do know this though...after comparing these cases with genuine cases there is very little difference in overall machine work and finish quality. Same goes for my 5512/13 Yuki cases along with one IG44 1680 case and one Phong 1655 case. If anyone took the time to detail finish these cases along with exact numbers/letters they would be very hard to tell from genuine after a couple years of daily wear. They are probably already out there, some with 'official replacement' 444 case numbers. Edit: I just remembered that genuine and many replica 5512/13/1680 cases have gaskets mounted in case backs and SD have them mounted in the cases...if MBK SD cases have the gasket mounted in the case, it means the MBK SD case backs are in fact different from 5512/13/1680.

UmpaHimself Posted March 1, 2016 Report Share Posted March 1, 2016 Just from eying it my 5512 and 5513 have the shorter, "correct" bezel Link to comment Share on other sites More sharing options...
highoeyazmuhudee Posted March 2, 2016 Report Share Posted March 2, 2016 On 2/29/2016 at 10:34 AM, automatico said: ... there were a lot of inconsistencies between MBK cases, some had better crown heights than others, some had better inserts than others (better numeral print and black finish), some had better 93150 bracelets than others (thicker, with brushed sides instead of polished sides). all within the same batch. i would buy 15-30 at a time back in 2012 and resell them. i even had some come with clone movements that were nickel plated with a pearlage finish back then.
