Franken 1680- MBW case- gen insert won't fit!

[username here]

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?

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.

^ 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.

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!

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!

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?
