username here Posted August 1, 2011 Report Share Posted August 1, 2011 I've got two gen inserts- neither will work on my MBW case: Gen insert measurement: inside Diameter -- 30.70 mm Outside Diameter - 37.57 mm MBW case: This is an older MBW 'Polex' 5513 case. in bezel for insert has a diameter of 36.6mm The crystal Outside Diameter is around 30mm From these measurements it looks like the diameter of the insert is over 1mm too large and the inside diameter is enough oversize that there would be an unsightly gap between crystal and insert. Has anybody else run into this problem when modding an MBW? Possible solutions? Quote Link to comment Share on other sites More sharing options...
alligoat Posted August 1, 2011 Report Share Posted August 1, 2011 You've got the wrong inserts! The 5513 insert is smaller and the ones you have are the 16800/16610 inserts. The 315-5513 will fit the 5513/5512/1680/1665 watches and the 315-16800 is for the later model sapphire date subs. There's also different inserts for the 14060 and the 16660/16600 SD's.

praetor Posted August 1, 2011 Report Share Posted August 1, 2011 ^ ditto... the size you're looking for is 36.6 outside and 30.3 on the inside. My 5513 case fits a 16800 insert though hahahha =D that's what I get for buying cheap. Quote Link to comment Share on other sites More sharing options...
username here Posted August 2, 2011 Author Report Share Posted August 2, 2011 Thanks. if anybody has the correct insert- i've got 2 16800's to sell! Also have a gen 7mm crown, gen DJ gold crown (came out of a 16223), gen DJ dial- prob a few other things that I could trade for the correct movement. LMK!

woof* Posted August 2, 2011 Report Share Posted August 2, 2011 The smaller gen 5512/1680 inserts are usually more $ and harder to come by in good condition than the modern saphire inserts Keep checking VRF and eBay ..good luck! Quote Link to comment Share on other sites More sharing options...

panerai153 Posted August 2, 2011 Report Share Posted August 2, 2011 what does everybody use normally for a franken 1680 with an MBW base? Mine has a genuine 1680 w/ tritium pearl. bought it off the VRF a couple of years ago. Fits the old MBW bezel fine. Quote Link to comment Share on other sites More sharing options...
username here Posted August 2, 2011 Author Report Share Posted August 2, 2011 Mine has a genuine 1680 w/ tritium pearl. bought it off the VRF a couple of years ago. Fits the old MBW bezel fine. yeah- it's probably the smaller size- they apparently fit fine. Just purchased a new insert- we'll see. The DW is having some issues- it's a ubi DW and not quite flat. I'm going to have it glued onto the ETA DW as an overlay. Should i be worried? Quote Link to comment Share on other sites More sharing options...
